Introduction and importance: Intracranial dermoid cysts are rare, constituting 0.04% to 0.6% of all intracranial tumors. They often arise from ectodermal cells trapped during neural tube formation. We report a case of spontaneous rupture of a large tentorial epithelioid cyst, which caused massive dissemination of liquid cholesterol into the subarachnoid cisterns and ventricles. Presentation of case: A 28-year-old male presented with a two-week history of headache and memory decline. CT and MRI revealed a 9x6 cm lesion in the left frontotemporal region with widespread dissemination of lipid droplets. Surgical resection was performed using a microscope combined with a neuroendoscope. Pathology confirmed a dermoid cyst. Clinical discussion: Ruptured dermoid cysts can cause significant symptoms due to the dissemination of cyst contents. Imaging is crucial for diagnosis and surgical planning. The combined microscopic and neuroendoscopic approach minimized blind spots and allowed thorough tumor exposure, facilitating complete resection with minimal residual complications. Postoperative outcomes were favorable, with imaging confirming substantial tumor removal and restored cerebrospinal fluid circulation. Conclusion: Prompt diagnosis and comprehensive surgical intervention are essential for managing ruptured intracranial dermoid cysts. Combined microscopic and neuroendoscopic techniques are effective in achieving extensive resection and reducing complications. [ABSTRACT FROM AUTHOR]

Mature ovarian dermoid cysts (ODCs) are the most common benign ovarian tumors diagnosed in children. However, there is minimal data on management of ODCs in premenarchal patients. This study assesses characteristics associated with expectant (EM) vs surgical (SM) management in premenarchal patients and the growth rate of ODCs in EM patients at a single institution. Forty-four premenarchal patients, either post-surgical with pathologically-confirmed ODC or having radiologic findings consistent with ODCs, were included. Data collected included demographics, cyst characteristics, imaging findings, presence of symptoms, surgical procedure performed, and ovarian torsion occurrence. Patient age at diagnosis was similar between groups (SM: 8.8 vs EM: 8.0, P =.55). At presentation, 36 patients (82%) underwent SM and 8 (18%) underwent EM. There was a significant difference in cyst size between groups (SM: 8.9 cm vs EM: 3.6 cm, P =.004). Of SM patients, 30% underwent oophorectomy vs cystectomy, with a significant difference in ODC size between procedures (11.8 cm vs 7.7 cm, P =.016). Of EM patients, 75% had at least one and 60% had three follow-up ultrasounds, with average follow-up timeframes of 3.7 and 27 months respectively. Average yearly ODC growth rate for the latter group was 0.8 cm. The average yearly growth rate of ODCs in premenarchal patients within our institution was slower than in older cohorts, and both age and cyst size played significant roles in determining surgical procedure. Continued study on EM in premenarchal ODCs will help define parameters for recommending SM vs EM in this population. [ABSTRACT FROM AUTHOR]

Acute appendicitis and adnexal torsion are leading causes of acute surgical abdomen in female patients. However, the simultaneous occurrence of these 2 conditions is extremely rare. Here, we present an extraordinary case of a woman radiologically diagnosed with ovarian dermoid torsion coexisting with acute appendicitis. The patient was managed operatively by surgeons from the respective fields in a single setting, thereby meeting the patient's standard of care. This case provides valuable insight into the possible coexistence of acute adnexal pathology with acute bowel pathology and vice versa, emphasizing that radiologists should avoid satisfaction of search after a single possible explanation of the condition.

Dermoid cysts represent the most frequent type of orbital cystic lesions observed in children. While superficial orbital dermoid cysts manifest early in life as slowly growing masses, deep dermoid cysts typically remain clinically undetectable until adolescence or adulthood, at which point they enlarge and induce proptosis. Imaging studies play a pivotal role in precisely determining location and size, excluding intracranial and intraorbital extensions, and facilitating the planning of management strategies for complex cases.We present a case of a 5-year-old boy admitted for slowly developing of ocular motility limitation of the right eye, observed by the parents. The imaging revealed a well-circumscribed extraconal cystic mass, with radiological characteristics primarily suggesting a dermoid cyst. The cyst was surgically excised without complications, and the histopathological examination of the operative specimen confirmed our diagnosis.

Abstract Cauda equina syndrome is a surgical emergency caused by the compression of the lumbosacral nerves. The most frequent cause is discal herniation, while tumoral pathology in this region is rare, and congenital processes are less common. We report the case of a young 37-year-old male patient, admitted to the emergency room with an incomplete cauda equina syndrome. As medical history, a lumbar surgery 15 years ago was reported with no documentation. An MRI was performed, revealing a mass within the filum terminal exhibiting three components suggestive of a dermoid cyst accompanying a split cord malformation, which was confirmed by pathology. Various disorders may be associated to intradural dermoid cyst, such as lipoma, low-lying cord, hydromyelia or thick filum. Surgery is the treatment of choice, and MRI plays a crucial role in detecting associated abnormalities and determining surgery priorities.

Dermoid cysts are benign tumors and occur very rarely in the cecum. To date, the literature shows very few cases to have been reported of a dermoid cyst in the cecum, one of which was laparoscopic. Even though dermoid cysts have ultrasonographic characteristic appearances, other pathologies in the pelvis can mimic this appearance. A 35-year-old female patient who had had a dilation and curettage a week prior was examined with a complaint of abdominal pain. A semisolid mass lesion with a size of 105x77 mm originating from the right lateral of the uterus was detected by transvaginal ultrasonography. During the operation, the frozen section of the mass was shown to not be malignant. The mass was removed by ileocecal resection. The surgery was terminated after ileocolonic anastomosis. The mass was examined histomorphologically and was reported as a dermoid cyst in the cecal colon. Cecal dermoid cysts should be considered for a differential diagnosis of pelvic cysts. A more detailed preoperative radiological imaging could have contributed significantly to the diagnosis. Surgical resection of a dermoid cyst in the cecal colon is a curative treatment. Due to the rarity of such cases, conduct a prospective study is quite difficult, which is what makes this study important. [ABSTRACT FROM AUTHOR]

Adeloye-Odeku disease was initially reported as an African congenital cyst in 1971, but this disease is now been documented worldwide. Adeloye-Odeku disease is classified as a congenital subgaleal inclusion dermoid cyst of the anterior fontanelle region. Mostly, this disease occurs in infants or children. This is the first case report of Adeloye-Odeku disease in Indonesia. The case report of a 5-month girl is presented with a lump that had developed since birth. The characteristic of lump was soft, non-tender, dome-shaped, and positive transillumination results. A computed tomography (CT) scan was carried out, with the result of a subgaleal dermoid inclusion cyst in the anterior fontanelle region. The anterior fontanelle appeared widened without intracranial expansion. Surgical excision of the cyst was performed under general anesthesia successfully. Histopathologic examination showed dermoid cysts without malignancy features. There were no complications reported when the patient attended the follow-up visit at the outpatient clinic. This is consistent with the existing literature on Adeloye-Odeku disease. [ABSTRACT FROM AUTHOR]

Objective: To describe the characteristics of pregnant women diagnosed with adnexal masses and review our experience with diagnosis, management and treatment modalities in this area for which there are no definitive treatment guidelines. Methods: All women with adnexal masses during pregnancy whose management and follow-up was completed at a large tertiary referral center between January 2018 and September 2023 were retrospectively evaluated. After applying the exclusion criteria, a total of 19 women who underwent antepartum laparoscopic adnexal surgery (group 1) and 34 women who underwent expectant management (group 2) were included. Results: Gestational age at birth, cesarean section rates, birthweight and APGAR-5 scores were similar, while the largest mass diameter and CA-125 levels were significantly higher in group 1 (p<0.001 and p=0.014, respectively). Of the patients in group 1, 15 (78.9%) had unilateral complex cysts and 4 (21.1%) had unilateral simple cysts, while there were no bilateral masses. Emergency laparoscopy was performed in 6 (31.6%) of patients for adnexal torsion and in 7 (36.8%) for cyst rupture, while elective laparoscopy was performed in 6 (31.6%) asymptomatic patients with suspected malignancy. While functional cyst was the most common histopathologic finding, malignancy was found in 2 cases (granulosa cell tumor and endometrioid adenocarcinoma). Preterm births occurred in 8 (41.1%) women, of whom 5 (26.3%) gave birth before 34 weeks' gestation and 3 (15.7%) between 34-36 weeks and 6 days. Conclusion: Parallel to the increase in ultrasound examinations in early pregnancy, both the overdiagnosis and early detection of adnexal masses during pregnancy have increased. Given the high rate of spontaneous regression in most lesions and the fact that bleeding in ruptured cases is usually self-limiting, an expectant approach would be appropriate in cases without hemodynamic instability, acute abdomen and/or suspected malignancy. Laparoscopy is a safe and efficient surgical approach for surgery. [ABSTRACT FROM AUTHOR]

Neonates are obligatory nasal breathers hence nasal obstruction is a very important symptom to be evaluated. Although causes can be trivial most of the time, they can be life-threatening in some. Respiratory distress immediately after birth, feeding difficulties, paradoxical cyanosis, and failure to thrive are the most evident symptoms, and determination of unilateral or bilateral involvement guides the rationale for elective or emergency intervention. This study aimed to evaluate the causes, presentation, and management of neonates with nasal obstruction. We collected the data of all the neonates evaluated for nasal obstruction at our hospital over the past 20 years from June 2003 to May 2023 and assessed the strategy of approach for diagnosis and management of those cases. In our study, the commonest cause for neonatal nasal obstruction was found to be choanal atresia and the rarest was iatrogenic. A variety of other causes were also reported. As neonatal nasal obstruction has a multitude of rare causes each carries a unique assessment and treatment plan. History taking and clinical examination are the most important parts of evaluation including endoscopic evaluation in an office-based setup. Imaging studies add to the evaluation of cases of anatomical obstructions and associated anomalies (syndromes). Early diagnosis and swift intervention can be life-saving. The need for follow-up visits and second-stage corrections should be emphasized in getting the best long-term results. [ABSTRACT FROM AUTHOR]

Teratomas are germ cell tumors, commonly affecting ovaries. Teratomas rarely affect extragonadal tissues. Few cases of teratomas occurring in extragonadal tissues have been reported in the past. However, no studies have reported cases of primary teratomas occurring in the broad ligament. In this study, we report a case of a sexually inactive young woman with a 3-day history of lower abdominal pain. B-ultrasound examination revealed an abnormal strong echogenicity mass in the left adnexal area. An exploratory laparotomy was performed on her. The surgery revealed normal size and appearance of both ovaries and uterus. However, a cyst was observed in the left broad ligament, which was diagnosed as benign mature teratoma based on pathology. In this study, we report a rare case of broad ligament teratoma. The clinical data enrich our understanding of teratomas and provide a reference for further studies. [ABSTRACT FROM AUTHOR]

Angiolipoleiomyoma is a benign mesenchymal mass composed of smooth muscle, mature adipose tissue, and abnormal blood vessels. It is rarely diagnosed in uterine masses and its prevalence among benign uterine lesions is 0.06%. We report the case of a 40-year-old female presenting with a complaint of heavy menstrual bleeding. Computed tomography scan revealed a large uterine mass with the right ovarian cyst. Histopathological examination confirmed the nature of the lesion as a benign angiolipoleiomyoma with a dermoid cyst of the right ovary. This rare association is reported to apprise gynecologists to consider this unusual tumor during the management of uterine masses.

Abstract Background Mature cystic teratoma co-existing with a mucinous cystadenocarcinoma is a rare tumor that few cases have been reported until now. In these cases, either a benign teratoma is malignantly transformed into adenocarcinoma or a collision tumor is formed between a mature cystic teratoma and a mucinous tumor, which is either primarily originated from epithelial-stromal surface of the ovary, or secondary to a primary gastrointestinal tract tumor. The significance of individualizing the two tumors has a remarkable effect on further therapeutic management. Case presentation In this case, a mature cystic teratoma is co-existed with a mucinous cystadenocarcinoma in the same ovary in a 33-year-old Iranian female. Computed Tomography (CT) Scan with additional contrast of the left ovarian mass suggested a teratoma, whereas examination of resected ovarian mass reported an adenocarcinoma with a cystic teratoma. A dermoid cyst with another multi-septate cystic lesion including mucoid material was revealed in the gross examination of the surgical specimen. Histopathological examination revealed a mature cystic teratoma in association with a well-differentiated mucinous cystadenocarcinoma. The latter showed a CK7−/CK20 + immune profile. Due to the lack of clinical, radiological, and biochemical discoveries attributed to a primary lower gastrointestinal tract tumor, the immune profile proposed the chance of adenocarcinomatous transformation of a benign teratoma. Conclusions This case shows the significance of large sampling, precise recording of the gross aspects, histopathological examination, immunohistochemical analysis, and the help of radiological and clinical results to correctly diagnose uncommon tumors.

Intracranial dermoid cysts are benign tumors of congenital origin. The intradiploic forms are rare, exceptional at the pterional level. We report the case of a 10-year-old girl who presented with a cutaneous fistula in the left frontotemporal region. The blind end of the fistula was an intradiploic dermoid cyst in the rare location of the pterion confirmed by imaging and histopathology. Once this lesion is suspected, it is important to identify its location and morphology using imaging techniques and to complete excision of the cyst to avoid complications associated with infection and to mitigate the risk of subtotal resection.

Presacral tumours are rare developmental tumours associated with midline closure defects. A fifteen-month-old girl presented with pain in the lower abdomen and dysuria. After examination, the child underwent investigations and was diagnosed as a presacral mass with intergluteal extension and caudal mass in the subcutaneous tissue of the left gluteal region. Complete excision of mass along with coccygectomy was done. Histopathology showed presacral as a keratinous cyst and gluteal as a dermoid cyst. Later on, the child also developed a left facial dermoid cyst which was also excised.

Background: Mature cystic teratomas or dermoid cysts of the pancreas complicate surgical approaches because of their anatomical position and ever-growing size. Herein, we report a case of a giant mature cystic teratoma of the pancreas that was successfully resected via complete laparoscopic distal pancreatectomy (LDP). Case presentation: A 39-year-old female patient was referred to our hospital for the evaluation of a pancreatic tumor. Three years of follow-up revealed that the tumor had increased in size to 18 cm, with hyperintense solid components on diffusion-weighted magnetic resonance imaging. Considering the possibility of malignancy, we decided to perform an LDP. The capsule appeared solid enough to withstand the retraction of the endoscopic forceps. Tumor size made it difficult to dissect the dorsal side of the tumor from the caudal to the cranial side. Early transection of the pancreas and additional ports facilitated dissection of the dorsal side of the tumor. We completed the LDP without intraoperative cyst rupture. On pathological examination, the tumor was diagnosed as a mature cystic teratoma originating from the pancreatic tail. The patient was discharged on postoperative day 13 with no complications. Conclusion: LDP may be an option for surgical procedures in patients with large cystic lesions of the pancreatic body or tail. Intraoperative observation of the tumor and surgical refinement are necessary to complete the laparoscopic procedure without tumor rupture. [ABSTRACT FROM AUTHOR]

(1) Background: Dermoid cysts occurring in the sublingual space are uncommon, typically manifesting as painless, gradually enlarging masses, usually not exceeding 3 cm in diameter. These cysts can resemble various conditions due to their clinical presentation, with a relatively low occurrence rate in the oral cavity, accounting for about 1.6% of all dermoid cysts. (2) Methods: We present the case of a 17-year-old female with a giant dermoid cyst involving the submental, sublingual, and lingual areas, undiagnosed for several years. Diagnosis was achieved through MRI and fine-needle aspiration, leading to the decision for surgical removal through a cervical approach. (3) Results: The healing process was uneventful. From the first day post-surgery, the patient began myofunctional therapy, successfully regaining proper tongue functions. Throughout a 24-month follow-up, the patient remained symptom-free. (4) Conclusions: A cervical approach can successfully treat giant oral dermoid cysts involving submental, sublingual, and lingual spaces. Tongue function can be successfully regained through myofunctional therapy after surgical treatment. [ABSTRACT FROM AUTHOR]

Mature cystic ovarian teratomas (MCT) are the commonest germ cell tumors accounting for about 30-45% of all ovarian neoplasms and 60% of all benign neoplasms arising in the ovary. Only 2% of MCTs undergo malignant transformation. We report a rare case of a 48-year-old woman diagnosed with a primary malignant struma ovarii arising in a dermoid cyst of the ovary. The patient was admitted with the complaint of pelvic pain and a pelvic mass in the lower abdomen on gynecological examination and ultrasonography showed a dermoid cyst of the ovary. Preoperative tumor markers and routine biochemistry were unremarkable. A laparoscopic left-sided salpingo-oophorectomy was done. Histopathology of the tissue showed a malignant struma ovarii and immunohistochemistry (CK-19 levels) similar to the guidelines for primary thyroid gland disease. The patient was subsequently taken up for staging laparotomy with total abdominal hysterectomy with right salpingo-oophorectomy and retroperitoneal pelvic and para-aortic lymphadenectomy and omentectomy. The histopathological report of all staging tissues was normal and surgical staging IA was assigned. Thyroglobulin level was monitored in the postoperative period. She is free of the disease for the last 2 years. [ABSTRACT FROM AUTHOR]

We present a case of craniofacial dermoid cyst in a 50-year-old female. The patient's complaint was persistent refractory headaches with no other significant neurological symptoms. Diagnostic imaging revealed the presence of a lesion in the left fronto-zygomatic region. Surgical intervention involved a craniotomy that led to a successful excision of the dermoid cyst. The diagnosis was subsequently confirmed by histopathological analysis. This case underscored the importance of considering DC as a potential diagnosis for any craniofacial lesion, given their diverse presentations and associated complications. [ABSTRACT FROM AUTHOR]

This is a case report of a 19-year-old nulligravid patient with a choroid plexus papilloma tumor in a mature cystic teratoma in the right adnexal area. The patient, who had abdominal pain and dyspepsia, showed a 9 cm diameter mass with a solid/cystic component, initially interpreted as a dermoid cyst in the right adnexal region. Mature cystic teratoma is a benign germ cell tumor and is common in women during the reproductive period. However, choroid plexus papilloma is a rare brain tumor. The diagnosis of ovarian choroid plexus papilloma can be made with imaging tests such as magnetic resonance imaging or computed tomography, and treatment is usually by surgical removal. Only four cases of ovarian teratoma with choroid plexus papilloma have been informed in the English literature, and this issue is the fifth. [ABSTRACT FROM AUTHOR]

Background: Dermal sinus tract is a rare type of spinal dysraphism. It is usually associated with other types of spinal congenital anomalies. This work shows the rare co-occurrence of primary and secondary neurulation defect in a single patient. Case presentation: We introduce a 2 year old boy who presented with a sacral dimple. He had a complex underlying spinal neural tube defect, dermal sinus tract, dermoid cyst, filum terminale lipoma, tethered spinal cord and syringomyelia. He was managed with excision of the dermal sinus tract, dermoid cyst and filum terminale lipoma with untethering of the spinal cord. He had a good post operative outcome without any neurologic deficit. Conclusion: This case shows how a simple skin dimple can be an indicator of underlying complex spinal dysraphism. It also shows the co-occurrence of primary and secondary neurulation defect which suggests the complex nature of the neurulation process.

Introduction: Cysticercosis is a parasitic infestation caused by Taenia solium, which is a pork tape worm. Humans are the definitive host, and pigs are the intermediate host. It is more prevalent in low socioeconomic regions with poor hygiene and among populations where undercooked pork is consumed. Case Presentation: We hereby report an uncommon site of cyst lodgment and duration of presentation in a 24-year-old male who presented with a firm, non-tender mass over the superomedial aspect of the right orbital rim, superior to the medial canthal tendon for the last 9 years. Chronic presentation and location of the mass led to the tentative diagnosis of a dermoid cyst. Hence, a CECT orbit was advised to assess the extent and attachment of the mass. Unexpectedly, a cystic lesion with hyperdense nidus, suggestive of cysticercosis, was identified. Histopathology of the excised mass confirmed the diagnosis of cysticercosis. Conclusion: Our case emphasizes the importance of an uncommon site and chronic presentation in cases of cysticercosis.

Abstract Background Dermoid cysts are developmental abnormalities occurring between the third and fifth week of embryogenesis. These lesions can initially develop as intracranial or extracranial and persist throughout the patient’s lifetime. While generally benign, their symptoms can be due to mass effect or local irritation secondary to rupture and release of contents, typically presenting as headaches and seizures. Intracranial dermoid cysts are rare and comprise less than 1% of all intracranial lesions, with rupture occurring approximately 0.18% of the time. Case presentation Our case describes a 42-year-old Hispanic female with a late-onset rupture of an intracranial dermoid cyst with associated new onset seizures. She underwent uncomplicated neurosurgical resection with mesh placement and was scheduled to follow-up as an outpatient. Conclusion To avoid rupture and associated sequelae in future patients, we recommend considering a more invasive approach as the initial strategy if internal cysts are relatively accessible.

Intracranial dermoid cyst (DC) is a rare benign, slow-growing lesion, most commonly arising along the midline. They can occur in the supratentorial compartment, very rarely involve the sellar region and only exceptionally are intrasellar. The aim of our study is to address the challenges in the diagnosis and management of sellar DCs. We performed a systematic review of sellar DCs, in keeping with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and described an intrasellar DC in a 32-year-old female who presented with bilateral blurring vision. The review identified 4 intrasellar, 29 suprasellar, and 28 parasellar cases. Intrasellar DCs more likely present with progressive visual impairment and pituitary hormone dysfunctions during the fifth decade of life. Suprasellar and parasellar DCs are typically diagnosed during the third decade of life because of diplopia, ptosis, trigeminal hypoaesthesia/para-esthesia or cyst's rupture. Sellar DCs are typically hypodense on computed tomography scans and contain calcifications. Magnetic resonance imaging features include T1 hyperintensity, T2 heterogeneous intensity, no restriction on diffusion-weighted images, and no contrast enhancement. Surgery is the treatment of choice. Gross total resection is achieved in 60% of intrasellar and 61.9% of suprasellar and parasellar DCs. Early postoperative complications are reported in 40.0%, 16.7%, and 23.8% of intrasellar, suprasellar, and parasellar DCs, respectively. Intrasellar DCs are rare lesions typically diagnosed later than suprasellar and parasellar DCs due to their different clinical presentations. However, they should be considered in the differential diagnosis of cystic lesions of the sella, including epidermoid cysts, craniopharyngiomas, Rathke's cleft cysts, and teratomas.

Dermoid cysts are common benign ovarian tumours arising from totipotent germ cells. We report a rare case of chemical peritonitis and prolonged fever following laparoscopic salpingo-oophorectomy for torsion of a large ovarian dermoid and discuss the management of this patient with prolonged hospital stay, antibiotics and anti-inflammatory use, repeated drainage of the collection as well as re-laparotomy. The occurrence of this rare condition can be extremely distressing for the patient and treating surgeon alike, as the recommendations for management are limited. The management of chemical peritonitis may require one or more surgical procedures along with prolonged anti-inflammatory therapy. [ABSTRACT FROM AUTHOR]

A 5-year-old neutered female mixed cat presented with reduced activity and ataxia of the hind limbs. Computed tomography and magnetic resonance imaging revealed an extradural mass compressing the spinal cord on the dorsal aspects from the 7th to 8th thoracic vertebra. Dorsal laminectomy was performed on the 7--8th thoracic vertebra and the cyst was totally removed, giving full resolution of the clinical signs. The cyst was diagnosed as a dermoid cyst. To our knowledge, this is the first report of feline dermoid cyst compressing the spinal cord that was diagnosed antemortem. The prognosis is favorable when the cyst is completely resected.

Epidermoid cysts are benign, rare which can occur all throughout the body of an individual. Their occurrence in the oral cavity is rare and is difficult to distinguish from other intraoral cysts. A 27-year-old female patient presented with a swelling to the oral and maxillofacial surgery department for the removal of the cystic lesion. Based on the clinical and radiographic features the provisional diagnosis was given as odontogenic keratocyst. But the histopathological examination revealed a stratified squamous cystic epithelium with abundant keratin suggestive of an epidermoid cyst. This case report presents an uncommon finding in the oral cavity with a history of teeth extraction. Based on these findings even though epidermoid cyst is rare it should be included in the differential diagnosis of radiolucent lesions of the jaws. [ABSTRACT FROM AUTHOR]

A 20-year-old female presents with a painless, progressive, normal color smooth surface sublingual swelling extending to chin that had gradually increased in size over the preceding 2 months, which severely impaired her speech and swallowing. Fine-needle aspiration biopsy was suggestive of benign cystic lesion. Following surgical excision, the mass was found to contain a large amount of sebaceous keratin material removed along with the entire capsule of the cyst. Definitive diagnosis was confirmed with histological examination. We report a case of dermoid cyst treated surgically through an intra-oral approach by preserving and relocating the Wharton's duct using micro-surgical repair to the floor of the mouth, thereby leading to a good cosmetic and functional result for the patient.

Patients with midline cutaneous anomalies of the craniospinal axis can be indicative of underlying embryonic defects, such as neural tube defects. Lack of familiarity with these midline aberrant skin findings may lead to misdiagnosis and delayed treatment. In this review, midline cutaneous anomalies of the craniospinal axis including aplasia cutis congenita, cranial and spinal dysraphism, and other developmental anomalies are explored in detail with emphasis on cutaneous clues to the diagnosis and appropriate workup.

This study aimed to evaluate the spontaneous recovery of bone deformity after surgical excision of craniofacial dermoid cysts in pediatrics. Pediatric patients who underwent excision of a dermoid cyst were included in the study. A prospective analysis was conducted to evaluate the amount of bone recovery by comparing the depth of bony concavity in the preoperative and postoperative (6 months) ultrasonography. In 145 of 187 patients with preoperative imaging available, the mean size of dermoid cysts was 1.4 cm3 (range, 0.1 to 9.5), and 41.4% (60/145 cases) showed cranial bone depression. In the comparison of preoperative and postoperative ultrasonography of 30 patients, the mean depth of bony cavity decreased significantly from 4.0 to 0.9 mm (p<0.001) after a mean of 6.7 months postoperatively. There was 13.3% (4/30) of mild (≤2.0 mm), 40.0% (12/30) of moderate (>2.0 to ≤4.0 mm), and 46.7% (14/30) of severe (>4.0 mm) depression, and the concavity depth significantly decreased in all groups (p = 0.028, mild; p<0.001, moderate; p<0.001 severe). Within the limitations of the study it seems that significant recovery of cranial bone depression does take place within 6 months after excision of craniofacial dermoid cysts in pediatric patients, saving the need for immediate reconstruction.

While mature cystic teratomas are relatively common ovarian neoplasms typically comprising of multiple embryologic cell types, a specific monodermal subtype involving thyroid tissue, struma ovarii, can rarely be seen. This case reviews typical imaging characteristics with MRI and ultrasound of struma ovarii and details possible complications from these masses with intraoperative and histologic correlation.

Retroperitoneal cystic tumours often cause a diagnostic dilemma and present several clinical challenges because of their rarity, relative late presentation, anatomical location, close relationship with several vital structures in the retroperitoneal space and the surgical expertise required for the management. We present three challenging retroperitoneal cystic space occupying lesions – hydatid cyst, dermoid cyst, and cystic lymphangioma. All 3 cases underwent surgery after initial diagnostic difficulty and had smooth postoperative recovery. Retroperitoneal cyst needs surgical expertise for complete excision which is often difficult due to neighbouring important vital anatomical structures.

The mature teratoma, also known as a dermoid cyst, is the most common type of ovarian teratoma (OT). They constitute 95% of all teratomas and 69% of germ cell tumors, and their heterogeneity leads to various clinical manifestations with a wide range of imaging presentations. We presented 2 patients undergoing pelvic magnetic resonance imaging (MRI) showing a mature cystic teratoma and pathologic examination confirming typical and atypical findings.

Hirschprung's disease is a congenital disorder characterized by aganglionic bowel, usually diagnosed in infancy. Here, we present a unique case of Hirschprung's disease diagnosed in a 29-year-old female with acute on chronic constipation. As part of her work up, a computerized tomography of her abdomen and pelvis revealed large, bilateral dermoid cysts. A diagnostic and therapeutic colonoscopy allowed manual disimpaction and decompression of her bowel, as well as biopsy attainment. Histopathology revealed absence of ganglionic cells on haematoxylin and eosin stain and calretinin immunostaining. This case underscores the diagnostic challenges of Adult Hirschprung's disease and how this impacts patient quality of life, as well as the work up and management of concurrent causes abdominopelvic conditions.

Background: Thyroglossal duct cysts and dermoid cysts both commonly present as midline neck lumps in children. They are treated as separate entities with different embryological origins. There are isolated reports of thyroid gland tissue in a dermoid cyst, concurrent thyroglossal and dermoid cysts, and cysts with mixed histology. It is not known if these are rare or common. Methods: All children undergoing excision of a congenital midline neck cyst between January 2017 and December 2022 were identified. Histopathology slides were reviewed in detail. Results: In 53 children, there were 26 thyroglossal duct cysts, 24 dermoids, 1 lymph node and 2 with no diagnostic material identified. Five dermoids (28 per cent) had associated thyroid gland tissue, and 1 (4 per cent) had hybrid histology with keratinising and respiratory epithelium. Infection occurred in 17 per cent of dermoids prior to excision and 8 per cent of dermoids recurred after excision. Conclusion: Hybrid histology, infection and recurrence are all common in midline neck dermoids. A new theory for their embryological origin is proposed, with the suggestion that some may need more extensive surgery. [ABSTRACT FROM AUTHOR]

Teratoma are germ cell tumors, most frequently arising in the gonads and retroperitoneal teratomas are rare, especially adrenal teratomas. Only a few case reports have been documented in the literature so far. We report the case of a 52-year-old asymptomatic male patient who had an incidental finding of a left adrenal teratoma during an abdominal computed tomography scan; due to the large size of the tumor, he underwent laparoscopic left adrenalectomy, and histopathological examination revealed a mature teratoma of the left adrenal gland, Patient recovering well after surgery and had no recurrence after 6 months of postoperative follow-up. The preoperative diagnosis of adrenal teratoma is challenging because imaging features are usually non-specific. Minimally invasive surgical resection is the best option for diagnosis and treatment of adrenal teratoma. [ABSTRACT FROM AUTHOR]
