Background Methods Results Conclusions One of the hereditary syndromes associated with multiple early‐onset basal cell carcinomas (BCCs) is basal cell nevus syndrome (BCNS), of which a minority is caused by germline SUFU mutations. Germline SUFU mutations show a spectrum of phenotypes, of which multiple hereditary infundibulocystic basal cell carcinoma syndrome (MHIBCC) is one. Patients with MHIBCC develop multiple basaloid skin tumors from middle age onwards.Three patients presenting with an MHIBCC phenotype were tested for a germline SUFU mutation. Skin biopsies were assessed by two dermatopathologists.Our study adds three new pathogenic SUFU variants, including a mosaic, to the current literature. Literature suggests a spectrum of phenotypes of patients carrying the same SUFU mutation, which ranges from the MHIBCC phenotype, to BCNS, to patients that develop life‐threatening brain tumors. This last risk is significantly higher in germline SUFU mutation carriers when compared to BCNS patients carrying germline PTCH1 mutations.Germline SUFU mutation carriers should be recognized as a distinct group of patients carrying specific health risks, independent of meeting the BCNS criteria. Phenotypic prediction based on the specific SUFU mutation seems unfeasible. It is of utmost importance that the less apparent MHIBCC phenotype is recognized, to provide (second generation) germline SUFU mutation carriers appropriate healthcare. [ABSTRACT FROM AUTHOR]

Managing advanced basal cell carcinoma (BCC) in patients with Gorlin-Goltz syndrome presents unique clinical challenges due to the tumor's aggressive nature and potential for widespread metastasis. This case study details a sequential treatment regimen for a 68-year-old female patient with an extensive, inoperable BCC. Employing a multimodal approach that integrates radiotherapy, the Hedgehog pathway inhibitor vismodegib, and High-Intensity Focused Ultrasound (HIFU), we demonstrate the potential for nearly complete remission in a patient with advanced BCC. Initial treatment with radiotherapy and vismodegib reduced tumor size significantly, but the largest mass displayed resistance over time, signifying the need for innovative therapies. Subsequent HIFU treatment targeted individual lesions, showcasing a non-invasive method that provided precise treatment while mitigating systemic side effects. The case emphasizes the necessity of continual adaptation in treatment plans to address the development of resistance and underscores the importance of incorporating new technologies and targeted therapies for complex BCC cases. The successful outcome of this integrated strategy suggests a promising direction for future research and highlights the importance of multidisciplinary approaches that tailor treatment to individual patient needs, tumor characteristics, and evolving therapeutic landscapes.

Abstract Background To demonstrate and analyze the 18F-FDG positron emission tomography/computed tomography (PET/CT) findings in this rare nevoid basal cell carcinoma syndrome (NBCCS). Case presentation A 71-year-old woman with the left invasive breast cancer was treated with hormone therapy for six months and underwent the 18F-FDG PET/CT examination for efficacy evaluation. 18F-FDG PET/CT revealed the improvement after treatment and other unexpected findings, including multiple nodules on the skin with 18F-FDG uptake, bone expansion of cystic lesions in the bilateral ribs, ectopic calcifications and dilated right ureter. She had no known family history. Then, the patient underwent surgical excision of the all skin nodules and the postoperative pathology were multiple basal cell carcinomas. Finally, the comprehensive diagnosis of NBCCS was made. The patient was still in follow-up. Additionally, we have summarized the reported cases (n = 3) with 18F-FDG PET/CT from the literature. Conclusions It is important to recognize this syndrome on 18F-FDG PET/CT because of different diagnoses and therapeutic consequences.

Simple Summary: Gorlin syndrome (GS) is a genetic disorder characterized by multiple basal cell carcinomas (BCCs) due to mutations in the hedgehog signaling pathway. Patients with GS may need dozens or even hundreds of surgical procedures in their lifetime, which can leave them severely scarred, deformed, and disfigured. In 16 patients with GS, we examined the effectiveness, safety, and length of response to oral hedgehog inhibitors. According to our retrospective study, sonidegib inhibited the growth of both newly diagnosed and pre-existing basal cell carcinomas more successfully and safely than vismodegib. Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome (GS), is a genetic disorder characterized by the development of multiple cutaneous BCCs due to mutations in the hedgehog signaling pathway. The use of hedgehog pathway inhibitors—vismodegib and sonidegib—has emerged as a promising therapeutic strategy for managing BCCs in individuals with GS. In a retrospective study conducted between March 2012 and January 2024, a cohort of 16 Gorlin syndrome patients who received treatment with either sonidegib or vismodegib were analyzed. The primary objectives of the study were to evaluate the efficacy, safety profile, and duration of response to oral hedgehog inhibitors in this patient population. The study assessed various parameters, including the number of new BCCs that developed before and after treatment initiation, the duration and sustainability of treatment responses, as well as the incidence of adverse effects associated with hedgehog inhibitor therapy. The findings of the study revealed that sustained treatment with hedgehog inhibitors could effectively suppress the progression of both new and existing BCCs. Furthermore, the results indicated that sonidegib exhibited superior efficacy and safety compared to vismodegib in the treatment of BCCs in individuals with GS. Notably, adjustments to the administration schedule of sonidegib were found to improve tolerability without compromising therapeutic efficacy, potentially leading to prolonged durations of treatment response and disease control.

- Abstract
Treatment with Hedgehog Inhibitors in Gorlin‐Goltz syndrome (GGS) yields favourable objective clinical responses, yet secondary resistance and class‐related toxicity restrict treatment duration. This study aims to review current data on GGS patients undergoing vismodegib therapy, focusing on treatment duration, clinical outcomes and schedule modifications. A systematic search of the PubMed database was conducted for English articles from 1993 to 2023, identifying 31 papers suitable for inclusion. A total of 351 patients, with a mean age of 52 years, were analysed. The average treatment duration was 9.3 months for patients who discontinued treatment, and 25.1 months for those who continued vismodegib at the time this study was published. Vismodegib achieved a complete response rate of 44%. Treatment interruption predominantly occurred due to side effects (69.1%) and secondary resistance (9.1%). The use of alternative regimens, although not compromising efficacy, may enhance treatment compliance. Further investigations are warranted to ascertain the optimal treatment regimen and timeline for GGS patients. Schedule modifications offer promise in ameliorating side effects and facilitating long‐term treatment. [ABSTRACT FROM AUTHOR]

- Abstract
In 2002, heterozygous suppressor of fused variants (SUFU+/−) in the germline were described to have a tumor suppressor role in the development of pediatric medulloblastoma (MB). Other neoplasms associated with pathologic germline SUFU+/− variants have also been described among patients with basal cell nevus syndrome (BCNS; BCNS is also known as Gorlin syndrome, nevoid basal cell carcinoma [BCC] syndrome or Gorlin‐Goltz syndrome; OMIM 109400), an autosomal‐dominant cancer predisposition syndrome. The phenotype of patients with germline SUFU+/− variants is very poorly characterized due to a paucity of large studies with long‐term follow‐up. As such, there is a clinical need to better characterize the spectrum of neoplasms among patients with germline SUFU+/− variants so that clinicians can provide accurate counseling and optimize tumor surveillance strategies. The objective of this study is to perform a scoping review to map the evidence on the rate of medulloblastoma and to describe the spectrum of other neoplasms among patients with germline SUFU+/− variants. A review of all published literature in PubMed (MEDLINE), EMBASE, Cochrane, and Web of Science were searched from the beginning of each respective database until October 9, 2021. Studies of pediatric and adult patients with a confirmed germline SUFU+/− variant who were evaluated for the presence of any neoplasm (benign or malignant) were included. There were 176 patients (N = 30 studies) identified with a confirmed germline SUFU+/− variant who met inclusion criteria. Data were extracted from two cohort studies, two case‐control studies, 18 case series, and eight case reports. The median age at diagnosis of a germline SUFU+/− variant was 4.5 years where 44.4% identified as female and 13.4% of variants were de novo. There were 34 different neoplasms (benign and malignant) documented among patients with confirmed germline SUFU+/− variants, and the most common were medulloblastoma (N = 59 patients), BCC (N = 21 patients), and meningioma (N = 19 patients). The median age at medulloblastoma diagnosis was 1.42 years (range 0.083–3; interquartile range 1.2). When data were available for these three most frequent neoplasms (N = 95 patients), 31 patients (32.6%) had neither MB, BCC nor meningioma; 51 patients (53.7%) had one of medulloblastoma or BCC or meningioma; eight patients (8.4%) had two of medulloblastoma or BCC or meningioma, and five patients (5.3%) had medulloblastoma and BCC and meningioma. This is the first study to synthesize the data on the frequency and spectrum of neoplasms specifically among patients with a confirmed germline SUFU+/− variant. This scoping review is a necessary step forward in optimizing evidence‐based tumor surveillance strategies for medulloblastoma and estimating the risk of other neoplasms that could impact patient outcomes.

Tooth eruption is an essential process for the development of the oral and maxillofacial system. Several inherited and acquired diseases might affect this tightly regulated process, resulting in premature, delayed, or even failed tooth eruption. The purpose of this article is to review the literature and the clinical parameters of metabolic bone diseases that affect tooth eruption. It examines the physiological aspects of tooth eruption and the pathophysiological changes induced by metabolic bone diseases, including changes in bone metabolism, density, and structure. The search strategy for this review included an electronic search in PubMed, Google Scholar, Medline, Scopus, and the Cochrane Library using the following keywords: "metabolic bone diseases", "tooth eruption", "delayed tooth eruption", and each reported disease in combination with "tooth eruption disorders", covering publications up to March 2024 and limited to English-language sources. Understanding the influence of metabolic bone diseases on tooth eruption is crucial for managing both dental and skeletal manifestations associated with these disorders. This review suggests that a multidisciplinary approach to treatment may significantly improve oral outcomes for patients suffering from such conditions. Clinicians should be aware of the specific dental abnormalities that may arise and consider comprehensive evaluations and individualized treatment plans. These findings underscore the need for further research into targeted therapies that address these abnormalities. [ABSTRACT FROM AUTHOR]

Objectives: Odontogenic keratocysts exhibit frequent recurrence, distinctive histopathological traits, a tendency towards aggressive clinical behavior, and a potential linkage to the nevoid basal cell carcinoma syndrome. The aim of this systematic review is to compile insights concerning the control of this condition and assess the effectiveness of various treatment approaches in reducing the likelihood of recurrence. Materials and methods: The following systematic review adhered to the PRISMA guidelines. The systematic revision was registered on PROSPERO and structured around the questions related to the population, intervention, control, outcome and study design (PICOS). Results: After conducting a search on the PubMed database, we initially identified 944 records. After using end-note software to remove duplicate entries, results totally with 462 distinct records. A thorough review of the titles and abstracts of these articles led to the selection of 50 papers for in-depth examination. Ultimately, following the application of our eligibility criteria, we incorporated 11 articles into our primary outcome analysis. Conclusion: Among the studies examined, the most common location for these lesions was found to be in the area of the mandibular ramus and the posterior region of the mandible. In cases where the exact location wasn't specified, the mandible emerged as the predominant site. When we considered the characteristics of these lesions in studies that mentioned locularity, most were described as unilocular in two studies, while in two other studies, the prevalence of multilocular lesions was observed. Risk factors associated with keratocyst recurrence include younger patient age, the presence of multilocular lesions, larger lesion size, and a longer anteroposterior dimension. Certain treatment methods have demonstrated a lack of relapses. These include the use of 5-fluorouracil, marsupialization, enucleation with peripheral ostectomy or resection, enucleation and curettage, as well as resection without creating continuity defects. However, it is important to note that further research is essential. Prospective studies and randomized trials are needed to collect more comprehensive evidence regarding the effectiveness of various treatment approaches and follow-up protocols for managing odontogenic keratocysts. Clinical relevance: Odontogenic keratocysts still enter into differential diagnoses with other lesions that affect the jaw bones such as ameloblastama and other tumor forms, furthermore it is not free from recurrence, therefore the therapeutic approach to the lesion aimed at its elimination can influence both the possible recurrence and complications, knowledge of the surgical methods that offer the most predictable and clinically relevant result for the management of follow-up and recurrences.

Cardiac tumours can occur in association with genetic syndromes. Rhabdomyomas have been reported in association with tuberous sclerosis, myxomas with Carney's complex, cardiac fibromas with Gorlin syndrome, and paragangliomas with multiple endocrine neoplasm syndrome. The presentation and prognosis of cardiac tumours associated with genetic syndromes differ compared with sporadic cases. Knowledge about the associated syndromes' genetic features and extracardiac manifestations is essential for the diagnosis, prognosis, and management of cardiac neoplasms. Moreover, identifying genetic mutations in benign and malignant cardiac tumours is needed to personalise management and improve treatment outcomes. Thus, this review discusses the genetic abnormalities associated with cardiac tumours, the current genetic screening recommendations, and the effect of those genetic mutations on the outcomes.

Promising research results have been obtained on the tissue-regeneration properties of PRF (platelet-rich fibrin) in dentistry and maxillofacial surgery. PRF presumably promotes healing and accelerates ossification. In this case report, the patient had a history of Gorlin–Goltz syndrome, also called nevoid basal cell carcinoma syndrome, an autosomal dominant neurocutaneous disease that was known for many years. As a consequence, cysts were detected in both the mandible and maxilla. We performed decompression on this 37-year-old patient, followed by a cystectomy on an extensive lesion in the right angle of the mandible. One cyst from each side of the body mandible and one from the maxilla were completely enucleated, as determined using an intraoral exploration. The resulting bone defect was filled with a composite graft composed of a mixture of A-PRF and a serum albumin-coated bone allograft (BoneAlbumin). The wound was then covered with a PRF membrane. The surgical sites were closed per primam. The postoperative period was uneventful. Biopsies were performed after three and six months of healing for histological micromorphometry analyses. Dental implants were placed at the sampling site. Three months after the implantation, the ossified implants were fitted with superstructures. To date, no complications have appeared with the bone augmentation. The authors interpret from the findings that the combination of A-PRF and BoneAlbumin can be validated as a prosperous bone substitute. It can be safely implanted after a 3-month ossification period.

Objective: Although Gorlin syndrome has rich skin findings, there is limited information about their subtypes, features specific to this genodermatosis, and relationships with each other. Materials and Methods: The demographic characteristics as well as cutaneous and extracutaneous findings of consecutive Gorlin syndrome patients diagnosed during 23 years were evaluated retrospectively. The relationship between palmoplantar pitting and basal cell carcinoma (BCC) in this localization and the relationship between odontogenic keratocysts (OKCs) and epidermoid cysts were investigated. Results: A total of 30 patients were diagnosed with Gorlin syndrome of whom 36.7% were children. BCC was the most common finding (90%) followed by OKCs (83.3%), skeletal system anomalies (76.7%), and palmoplantar pitting (76.7%). While classical BCC (63.3%) lesions were the predominant clinical subtype among all patients, acrochordon-like or small-sized papular BCCs were seen in 45.4% of pediatric patients. Three patients, 2 of whom were children, had BCC lesions in the palmoplantar region in association with palmoplantar pitting. Epidermoid cysts presenting clinically as solitary (n = 12) or a few nodules (n = 4) without punctum, located more commonly in acral areas (n = 10) were seen in 16 (53.3%) patients of whom 7 were children. Epidermoid cysts were seen in 60% of patients with OKCs, and the relationship between epidermoid cysts and OKCs was not statistically significant (P = .15). Extracutaneous tumors such as medulloblastoma (n = 3), cardiac fibroma (n = 1), and ameloblastoma (n = 1) were also recorded. Conclusion: The awareness of papular or acrochordon-like BCCs, palmoplantar BCCs, and acral epidermoid cysts without punctum may facilitate early diagnosis of Gorlin syndrome in children.

Gorlin–Goltz syndrome (GGS) is a rare hereditary disease characterized by multiple basal cell carcinomas, odontogenic keratocyst (OKCs) and musculoskeletal malformations. Pathogenesis of the syndrome is attributed to abnormalities in the long arm of chromosome 9 (q22.3–q31) and mutations in the human patched gene (PTCH1 gene). Here, we report a rare case of an incidental finding of GGS in an 18-year-old male patient presenting multiple OKCs, calcification of the falx cerebri, and bifid rib. [ABSTRACT FROM AUTHOR]

Basal cell nevus syndrome (BCNS) is an inherited disorder characterized mainly by the development of basal cell carcinomas (BCCs) at an early age. BCNS is caused by heterozygous small-nucleotide variants (SNVs) and copy-number variants (CNVs) in the Patched1 (PTCH1) gene. Genetic diagnosis may be complicated in mosaic BCNS patients, as accurate SNV and CNV analysis requires high-sensitivity methods due to possible low variant allele frequencies. We compared test outcomes for PTCH1 CNV detection using multiplex ligation-probe amplification (MLPA) and digital droplet PCR (ddPCR) with samples from a BCNS patient heterozygous for a PTCH1 CNV duplication and the patient's father, suspected to have a mosaic form of BCNS. ddPCR detected a significantly increased PTCH1 copy-number ratio in the index patient's blood, and the father's blood and tissues, indicating that the father was postzygotic mosaic and the index patient inherited the CNV from him. MLPA only detected the PTCH1 duplication in the index patient's blood and in hair and saliva from the mosaic father. Our data indicate that ddPCR more accurately detects CNVs, even in low-grade mosaic BCNS patients, which may be missed by MLPA. In general, quantitative ddPCR can be of added value in the genetic diagnosis of mosaic BCNS patients and in estimating the recurrence risk for offspring. [ABSTRACT FROM AUTHOR]

Basal cell carcinoma (BCC) is the most common skin cancer, for which there are multiple treatment options, including the gold standard Mohs micrographic surgery (MMS), surgical excision, electrodesiccation and curettage, radiation therapy, cryosurgery, and photodynamic therapy (PDT). While PDT is currently approved for treating actinic keratosis, it has been used off-label to treat BCC patients who may not tolerate surgery or other treatment modalities. We present a review of the efficacy of these modalities and describe important considerations that affect the usage of PDT and MMS. ALA-PDT and MAL-PDT are both efficacious treatment options for lower-risk BCC that can serve as non-invasive alternatives to surgical excision with favorable cosmetic outcomes in patients unsuitable to undergo surgery. In particular, PDT may be considered an adjuvant for the prevention and treatment of BCC lesions in patients with some genetic syndromes such as Gorlin syndrome, and in combination with surgical excision in lesions presenting in certain locations. Limitations to PDT include lack of margin control to prevent recurrence, pain, and cost of certain photosensitizers. Future studies should investigate the role of PDT as adjunctive therapy, standardization of protocols, and causes and ways to address recurrence following PDT treatment. [ABSTRACT FROM AUTHOR]

Gorlin-Goltz syndrome or basal cell nevi syndrome is an ectodermal neoplasia of autosomal dominant inheritance. It is a multisystem disease with a prevalence of 1 case per 57 000 to 150 000 people. It predominates in patients between the second and third decade of life, with a predilection for the male sex., Iit's characterized by the presence of multiple basal cell nevus carcinomas, development of odontogenic keratocystic and palmo-plantar pits or dimples and calcification of the falx brain. Odontogenic keratocysts (OKC) occur in more than 80% of cases of patients with Gorlin-Goltz syndrome (GGS). OKC can present as the first sign of GGS. Approximately 65% of cases affect the mandible, with high frequency in the molar and ramus region. A clinical case is presented of a 35-year-old male patient with a current condition of missing teeth. Physical examination revealed syndromic facies. Orthopantomography is requested, observing multiple radiolucent areas of various sizes as well as retained dental organs, so vacuum puncture and incisional biopsy were taken.; Histopathological result: odontogenic keratocyst and suspicion of GGS because the patient meets the major and minor criteria; complementary studies were requested to confirm the diagnosis. Enucleation of cystic lesions with peripheral ostectomy, extraction of retained and excision of the skin lesion was performed under general anesthesia. After one year, the healing process and bone regeneration was observed without signs of recurrence. The patient was kept under control and monitored by our service with annual appointments.

Simple Summary: Congenital tumors are an uncommon finding on prenatal ultrasound and in the first 3 months of life, and they are (almost) always subjected to magnetic resonance imaging. Although they are usually easy to recognize as pathological masses, differential diagnosis is not easy and includes both benign and malignant conditions. Teratomas are the most frequent group of inborn neoplasms, followed by cardiac rhabdomyomas. In this paper, the authors show a series of cases in order to provide tips to identify the more common masses and to keep in mind that the most unusual tumor may occur as congenital and that no diagnosis should be rejected a priori. The article is intended to raise awareness and draw attention to this little-known group of cancers and facilitate the diagnostic process. Congenital tumors are rare and, owing to this rarity, there is limited information on many of them. A total of 839 fetal and postnatal MRI studies performed in the first 3 months of life were retrospectively reviewed. They were performed with the use of 1.5 T scanners. Seventy-six tumors were diagnosed based on fetal MRI between 20 and 37 gestational weeks, and 27 were found after birth, from 1 day of age to 3 months of life. Teratomas were the most common tumors in our dataset, mainly in the sacrococcygeal region (SCT), followed by cardiac rhabdomyomas and subependymal giant cell astrocytomas (SEGA) associated with TSC, and neuroblastomas. The group of less common tumors consisted of infantile fibrosarcomas, malignant rhabdoid tumors, mesoblastic nephromas and Wilms tumor, craniopharyngiomas, brain stem gliomas, desmoplastic infantile astrocytoma, choroid plexus carcinoma, glioblastoma, hemangiopericytoma, rhabdomyosarcoma, melanoma, mesenchymal hamartomas of the chest wall and the liver, and juvenile xanthogranuloma, with special consideration of blue rubber bleb nevus syndrome. MRI plays a significant role in further and better characterization of congenital tumors, leading to a correct diagnosis in many cases, which is crucial for pregnancy and neonatal management and psychological preparation of the parents. No diagnosis is impossible and can be absolutely excluded. [ABSTRACT FROM AUTHOR]

BASAL cell nevus syndrome ,CONFORMATIONAL analysis ,GENETIC mutation - Abstract
Objective: To analyse the aetiology and pathogenesis of Gorlin-Goltz syndrome (GS; also known as nevoid basal cell carcinoma syndrome [NBCCS] or basal cell nevus syndrome [BCNS]) in a Chinese family. Methods: Whole-exome sequencing (WES) was performed on genomic DNA samples from the subjects in a family, followed by the investigation of pathogenesis via bioinformatic approaches and conformational analysis. Results: A novel heterozygous non-frameshift deletion patched 1 (PTCH1) [NM_000264: c.3512_3526del (p.1171_1176del)] was identified by WES and further validated by Sanger sequencing. Bioinformatic and conformational analysis showed that the mutation caused altered PTCH1 protein structure, which may be related to functional abnormalities. Conclusion: This study expands the mutation spectrum of PTCH1 in GS and facilitates the early diagnosis and screening of GS. PTCH1 [c.3512_3526del (p.1171_1176del)] may cause structural abnormalities and functional disabilities, leading to GS in families. [ABSTRACT FROM AUTHOR]

Introduction: Gorlin-Goltz syndrome also known as Nevoid Basal Cell Carcinoma Syndrome is a rare phakomatoses inherited as an autosomal dominant disorder characterized by mutations of PTCH-1 gene along with microdeletion of chromosome 9q. It is manifested by multiple tumours and abnormalities most importantly featured with multiple basal cell carcinoma, Odontogenic Keratocyst (OKC) and other skeletal disorders. Case Report: A 11- year-old girl having facial asymmetry and pain on the right side of the jaw reported to the department. Radiographic examination revealed multiple radiolucencies in the mandible. The biopsy and histopathological examination confirmed the presence of multiple OKC. Further investigations led to the case fulfilling 3 major criteria of multiple OKC, falx and tentorium cerebelli calcifications, palmar and plantar pits which established the diagnosis of Gorlin-Goltz syndrome. Conclusion: Being a condition requiring a multidisciplinary approach, early diagnosis and appropriate prophylactic measures along with proper treatment is essential for a better prognosis.

Background: Gorlin syndrome (GS) is a rare genetic disorder inherited in an autosomal dominant manner caused by genetic variants in PTCH1, SUFU, or PTCH2 genes. It is characterized by multiple basal cell carcinomas, odontogenic keratocysts, skeletal abnormalities, and predisposition to neoplasms. Case presentation: A novel splice-site variant in the PTCH1 gene, c.3549+1G>T classified as pathogenic, was identified in a patient with a phenotype compatible with GS (multiple basal cell carcinomas and skeletal malformations). Conclusions: This case contributes to expand the spectrum of identified variants in Gorlin syndrome increasing knowledge about molecular bases and the diagnosis approach of this syndrome.

BASAL cell nevus syndrome , *MOHS surgery - Abstract
BACKGROUND: The lifetime risk for basal carcinoma (BCC) is 90% in patients with Gorlin syndrome, also known as basal cell nevus syndrome. Compared with non-Gorlin patients, Gorlin patients often develop BCCs at a younger age and in greater numbers up to 500 BCCs in a lifetime. OBJECTIVE: To review the options available for Gorlin patients and highlight existing knowledge gaps where future studies are indicated to optimize the care of this unique population. METHODS: We review the current literature on managing patients with Gorlin syndrome from the lens of a dermatologic surgeon. RESULTS: Although Mohs surgery is still the gold standard for large and aggressive BCCs, other less-invasive approaches may be considered for smaller, more numerous lesions. As dermatologic surgeons, we must be open to the full spectrum of surgical and nonsurgical options to individualize treatment and optimize patients' quality of life. Without maintaining a balance between optimal cure rate and volume management, Gorlin patients become at risk for surgical burn out and loss to follow-up. CONCLUSION: Gorlin patients undergo numerous surgeries especially on the central face which can lead to disfigurement and reduce the quality of life. Identifying gaps in the current literature, continuing ongoing research, and eventually establishing appropriate guidelines that help to guide the formation of an individualized treatment plan is crucial in developing a balance between conservative and complex treatments for this population.

Background: Gorlin-Goltz's syndrome (GGS) is an extremely rare autosomal dominant disorder showing a high penetrance and variable expressivity. Gorlin-Goltz's syndrome is an infrequent multisystemic disease, which is usually characterized by numerous basal cell carcinomas, odontogenic keratocysts (OKCs), and musculoskeletal malformations along with neurological, ophthalmic, endocrine, and genital manifestations. There are also multiple manifestations in the domain of ENT and patient may primarily present to an ENT clinician with one of the diverse clinical involvements. Case presentation: We report one such infrequent case of a 24-year-old male patient who presented with an oroantral fistula at our tertiary health care center and was diagnosed to have Gorlin-Goltz's syndrome. The diagnosis was made in our patient by the presence of 4 major and 2 minor criteria. Conclusion: Early diagnosis and management of GGS helps to prevent long-term sequelae including malignancy and oro-maxillofacial deformation. The constellation of symptoms of such rare disorders should be promptly recognized and a high index of suspicion should be maintained. This case report is an appraisal of the diagnosis and management of GGS from an otolaryngological perspective and is being reported here for extreme rarity and clinical interest.

Gorlin‐Goltz syndrome (GGS) is an autosomal dominant multisystemic disease with high penetrance. Headache heralding GGS has been previously reported but without discussing potential sources. We report a patient with headache and a novel association (diastematomyelia), which helped with the diagnosis. A 46‐year‐old woman presented with persistent holocranial headache. On examination, countless hyperpigmented basal cell nevi over the face, pits over the palmar/plantar surface, and palmar and plantar keratosis were observed. A magnetic resonance imaging (MRI) of the spinal cord revealed diastematomyelia. Diagnosis of GGS was finally made. Headache and diastematomyelia should be included in the clinical picture of GGS.

Basal cell nevus syndrome is a genetically linked multisystem disorder with a hallmark tendency for development of multiple basal cell carcinomas at a young age. It is associated with a multitude of other anomalies including keratocytes of the jaw, palmar or plantar pits, and ectopic intracranial calcifications. This disease is most commonly caused by loss of function in tumor suppressor gene PTCH1 resulting in overactivation of the Hedgehog pathway and basal cell carcinoma formation. Diagnosis is largely clinical; patients must meet criteria of both major and minor categories. Genetic testing is warranted in specific situations where clinical diagnosis is unclear or for genetic counseling purposes. Given that basal cell carcinoma is a very common dermatologic disorder, it is important to recognize when it arises in the setting of genetically associated diseases. Early detection allows for proper management and surveillance of not only basal cell carcinomas but also the other multisystem effects of basal cell nevus syndrome. This review gives an in-depth overview of the etiology, pathogenesis, diagnosis, and management of basal cell nevus syndrome. [ABSTRACT FROM AUTHOR]

BASAL cell nevus syndrome - Abstract
Follow-up studies on odontogenic keratocysts have reported widely varying recurrence rates. This raises the question of how reliable these studies are and how the results should be interpreted. The aim of this study was to critically assess the information from all follow-up studies published since 2004 against a set of criteria to determine how thorough the study was. These criteria include the exclusion of the orthokeratinized variant, exclusion of cysts associated with nevoid basal cell carcinoma syndrome, and appropriate reporting of dropouts. A search of four electronic databases covering the years 2004–2022 was performed. Only studies with a sufficient follow-up period (covering a range of 1–8 years) were included. Studies with fewer than 40 cases were excluded. Fourteen relevant studies were identified in the literature search. The vast majority of these studies had considerable shortcomings, giving rise to serious doubts about the validity of their recurrence rate results. Of note, these studies have often been included in meta-analyses that report on the best treatment options to reduce the tendency of recurrences. The results of this review strongly suggest that multicentre studies with strict protocols should be performed to advance knowledge of the presentation of recurrences, both the timing and frequency.

- Abstract
Gorlin-Goltz syndrome, also known as Gorlin syndrome, basal cell nevus syndrome, and nevoid basal cell carcinoma syndrome, is an autosomal dominant genetic disorder. Its hallmark is an early onset of basal cell carcinoma. Additionally, the syndrome is characterized by a spectrum of distinct clinical attributes encompassing oral, skeletal, ophthalmic, neurological, and developmental aberrations. This condition arises due to anomalies in the Hedgehog signaling pathway, leading to constant pathway activity and uncontrolled growth of tumor cells. Early identification of the disorder through available diagnostic methods and clinical and radiological findings is crucial for accurate diagnosis, which subsequently leads to the formulation of an effective treatment regimen. The purpose of this case report is to discuss the role of a dentist in early detection based on various author-prescribed criteria and the need for a multidisciplinary approach to the treatment of patients with this syndrome.

Background: Nevoid basal cell carcinoma syndrome (NBCCS, Gorlin syndrome) is a rare autosomal dominantly inherited disorder that is characterized by multisystem disorder such as basal cell carcinomas, keratocystic odontogenic tumors and skeletal abnormalities. Bilateral and/or unilateral ovarian fibromas have been reported in individuals diagnosed with NBCCS. Case presentation: A 22-year-old female, presented with low back pain, and was found to have bilateral giant adnexal masses on pelvic ultrasonography, which had been suspected to be malignant ovarian tumors. Positron emission tomography/computed tomography showed multiple intracranial calcification and skeletal abnormalities. The left adnexa and right ovarian tumor were resected with laparotomy, and pathology revealed bilateral ovarian fibromas with marked calcification. We recommended the patient to receive genetic testing and dermatological examination. No skin lesion was detected. Germline testing identified pathogenic heterozygous mutation in PTCH1 (Patched1). Conclusions: The possibility of NBCCS needs to be considered in patients with ovarian fibromas diagnosed in an early age. Skin lesions are not necessary for the diagnosis of NBCCS. Ovarian fibromas are managed with surgical excision with an attempt at preserving ovarian function. Follow-up regime and counseling on options for future fertility should be offered to patients.

Nevoid basal-cell carcinoma syndrome (Gorlin syndrome) is characterized by numerous cutaneous basal cell carcinomas mediated by mutations in the hedgehog pathway. Vismodegib or sonidegib represent promising treatment options. We identified 10 Gorlin patients who were treated with sonidegib (n = 6) or vismodegib (n = 4) between March 2012 and March 2022. We analyzed the activity, toxicity, and duration of the response to oral hedgehog inhibitors. The number of new tumors that developed prior to treatment or after treatment as well as the time of response and durability of responses were assessed. All patients achieved a complete remission. With a 30.7 ± 48.4-month median follow-up, the drug treatment significantly reduced the number of new basal cell cancers from a mean of 28.3 ± 24.6 prior to treatment to a mean of 1.4 ± 2.0 during treatment (p = 0.0048). The median time to develop a new basal cell cancer was 47.3 months. Three patients eventually developed localized recurrences. After resection, ongoing treatment suppressed the development of additional lesions. One patient developed numerous new drug-resistant basal cell cancers and died of acute leukemia. Six patients required treatment modifications for toxicity. Sustained hedgehog inhibitor treatment can suppress the progression of both new and existing basal cell carcinomas for an extended period. Drug administration schedule adjustments improved tolerance without altering efficacy, potentially contributing to a prolonged response duration. [ABSTRACT FROM AUTHOR]

Introduction: Hybrid odontogenic lesions combine characteristics of two or more lesions in a single site, and they are considered a rare condition. The occurrence of these lesions in patients with Gorlin-Goltz syndrome is even less common. Since the lesion has variable clinical aspects and multiple imaging characteristics, histopathological examination is mandatory for a definitive diagnosis. Methods: This article reports the case of a patient with Gorlin-Goltz syndrome, who had multiple odontogenic keratocysts in the mandible and maxilla, as well as a combined/hybrid ameloblastoma and odontogenic keratocyst lesion. Results: Distinct areas with histological patterns characteristic of the cyst and tumor were observed within the same lesion. Conclusion: This unusual but still possible diagnosis should be considered by pathologists and oral and maxillofacial surgeons when evaluating, diagnosing and treating patients with syndromes characterized by odontogenic lesions.

Basal cell carcinomas (BCCs) are malignant, locally invasive, slow-growing tumors that arise from basal cells and represent 75% of non-melanoma skin cancers. BCC has many different clinical presentations, but the most common types include nodular, micronodular, superficial, morpheaform, infiltrative, and fibroepithelioma of Pinkus. These neoplasms develop in 80% of cases in sun-exposed areas of the head and neck, and only a minority of cases have been reported arising in the nipple-areola complex. In these locations, Paget's disease of the breast has to be first ruled out before BCC could be considered. Furthermore, since most BCCs occur in adult age, cases that appear earlier in childhood with increased number and unusual distribution should be checked for genetic disorders such as Basal cell nevus syndrome. Thus, we reported an original case of superficial BCC of the nipple-areola complex masquerading as Paget's disease of the breast and revealing a Basal cell nevus syndrome. [ABSTRACT FROM AUTHOR]

Basal cell nevus syndrome (BCNS, OMIM 109400) is a familial cancer syndrome characterized by the development of numerous basal cell cancers and various other developmental abnormalities, including epidermal cysts of the skin, calcified dural folds, keratocysts of the jaw, palmar and plantar pits, ovarian fibromas, medulloblastomas, lymphomesenteric cysts, and fetal rhabdomyomas. BCNS shows autosomal dominant inheritance and is caused by mutations in the patched 1 (PTCH1) gene and the suppressor of the fused homolog (SUFU) gene. In a few cases, variants of patched 2 (PTCH2) have been found in patients who met the criteria for BCNS. In an investigation of 11 Hungarian families who fulfilled the diagnostic criteria for BCNS, whole-exome sequencing (WES) and multiplex ligation-dependent probe amplification (MLPA) identified two novel pathogenic variants (c.2994C>A; p.Cys998Ter and c.814_818del; p.Asn272SerfsTer11), one recently identified variant (c.1737_1745del p.Val580_Val582del), and three recurrent disease-causing variants of the PTCH1 gene with a diagnosis rate of 63.6%. Disease-causing variants were not found for the SUFU and PTCH2 genes. These applied methods could not fully elucidate the genetic background of all the BCNS cases that we investigated. To uncover the missing heritability of BCNS, whole-genome sequencing or an epigenetic approach might be considered in the future.
