Dear Editor, Adamantiades-Behçet's disease (ABD) is an inflammatory disease classified as vasculitis, which was originally diagnosed in patients with aphthous stomatitis, genital ulcerations, and ocular manifestations. However, any organ or system may be involved, particularly the central and peripheral nervous systems, joints, as well as the gastrointestinal tract. The etiology of ABD is still not fully understood, but some evidence indicates that an autoimmune process could be triggered by an infectious or environmental agent specific for the geographic region (1). Although BD can occur worldwide, it is most prevalent in the region along the ancient commercial route called the "Silk Road". In Italy, studies on the precise prevalence of ABD are lacking (2). As there are no specific diagnostic laboratory tests or histopathologic findings which confirm the preliminary diagnosis, the final diagnosis should be based on clinical criteria (3). Skin and mucosae are the target organs of this disease, and therefore their involvement has been considered in the numerous diagnostic criteria developed over the years (4). The first most important and popular criteria were created in 1990 by the International Study Group (ISG) (5). Because of their low sensitivity, the new International Criteria for Behçet's Disease (ICBD) were established, and were presented at the International Conference of Behçet's Disease in Lisbon in 2006 (6,7). In 2014, the International Team for the Revision of the International Criteria for BD submitted new criteria assigning 2 points to ocular lesions, oral aphthosis, and genital aphthosis, and 1 point to skin lesions, central nervous system involvement, and vascular manifestations. The pathergy test, when used, was assigned 1 point. A patient scoring ≥4 points is classified as having BD (8). We performed a single center, case-control study on a cohort of patients of Friuli Venezia Giulia, enrolled from January 2010 to September 2015 in the Dermatology Unit of the University of Trieste. The aim was to analyze the clinical features and compare the sensitivity, specificity, and accuracy of the three diagnostic criteria for ABD presented above in patients born in this particular region which is located at the very start of the "Silk Route". We enrolled 153 consecutive patients (74 cases and 79 controls) in the study. The characteristics and clinical features of patients and controls are summarized in Table 1. The most common diagnoses in the control group were recurrent oral aphtosis, lichen planus, mucous-membrane pemphigoid, and lupus erythematosus. The inclusion criterion was the presence of at least one principal clinical feature of ABD (oral aphtosis, genital aphtosis, skin lesions, ocular involvement) properly recorded in clinical records. Patient recruitment was done in a consecutive manner. Exclusion criteria were incomplete clinical records and absence of follow-up data. The diagnosis of ABD was established by expert dermatologists, without the use of any particular diagnostic criterion. For ABD, diagnosis agreement among dermatologists was required. The study was conducted according to the Declaration of Helsinki protocols. Possible associations between categorical variables were detected by the use of Fisher's exact test or Pearson χ2 test, depending on the sample size. Logistic regression was performed in order to identify which symptoms are of higher impact in the diagnosis of ABD. A comparison in terms of sensitivity, specificity, and accuracy among the three diagnostic criteria (ISG 1990, ITR 2006, and ITR 2014) was performed. The receiver operator characteristic (ROC) curve was obtained for each diagnostic criterion. Data were produced with a 95% confidence interval; P values0.05 were considered statistically significant. Statistical analysis was done using Stata SE12 software (Stata Corporation, Tx, USA). According to our data, patients with ABD had a significantly lower age at diagnosis compared with controls (P=0.0001); this was confirmed for both men (P=0.0006) and women (P=0.004). The presence of oral aphtosis was not necessarily pathognomonic of ABD (P=0.005) as it was found in 97.3% of patients with ABD and in 83.5% of controls. Genital aphtosis was directly associated with ABD diagnosis (P0.001), as it was present in 79.7% of patients with ABD, but in only 8.9% of controls. Furthermore, even skin manifestations and ocular lesions were observed at different rates in patients with ABD and controls (P0.001 and P=0.003, respectively). The presence of pseudofolliculitis was significantly more frequent in patients than in controls (P0.001), whereas erythema nodosum and skin aphtosis did not differ considerably between ABD and controls. Joint manifestations were as common in patients with ABD as in controls (P=0.6): arthralgia and arthritis alone do not indicate a diagnosis of ABD. Neurological symptoms as well as vascular involvement, if present, can be suggestive of ABD, but their absence does not exclude an ABD diagnosis (P=0.06 and P=0.04). Positive pathergy tests and positive HLA B51 tests were significantly more frequent in patients than in controls (P=0.007 and P=0.009, respectively), although if negative they did not exclude a diagnosis of ABD. Logistic regression showed that genital aphtosis (odds ratio (OR)=12948, P0.001), neurological manifestations (OR=819.263, P=0.001), vascular manifestations (OR=240.2573, P=0.001), cutaneous manifestations (OR=104.5625, P=0.002), oral aphtosis (OR=145.3229, P=0.004), and younger age at diagnosis (OR=0.8950334, P=0.000) were associated with ABD diagnosis (Table 2). There was no single pathognomonic symptom of ABD. We found that the ITR criteria -both from 2006 and 2014 - had a higher sensitivity (98.7% and 100%, respectively), specificity (94.9% and 97.9%, respectively), and accuracy (96.7% and 98.7%, respectively) compared with the ISG 1990 criterion, which scored 66% sensitivity, 100% specificity, and 83.7% accuracy. Area Under Roc Curve (AUC) was significantly different between ISG 1990 and ITR 2006 and between ISG 1990 and ITR 2014 (Figure 1). Even though no statistically significant difference was found between the ITR 2014 and ITR 2006 criteria, the former had a better performance according to our records. The clinical features reported in our retrospective case-control study are comparable to data found in the literature from European and international reports. A recent study (8) found a similar organ involvement percentage to our study, although we found a higher prevalence of HLA B51 positive patients and a lower percentage of ocular manifestations in our records. The results of the logistic regression performed based on our records indicate genital aphtosis, oral aphtosis, ocular involvement, neurological signs, and vascular features are more strongly linked to the diagnosis of ABD. According to our data, the presence of oral aphtosis is not paramount for the diagnosis of ABD, which fits well with the intent of the ITR 2006 and 2014 diagnostic criteria. The new ITR 2014 criteria added neurological signs to the diagnostic symptoms of ABD, emphasizing the importance of a multidisciplinary approach to patients suspected to have ABD.

Strontium ranelate, which is used for postmenopausal osteoporosis, has been associated with drug rash with eosinophilia and systemic symptoms (DRESS) syndrome, a severe, acute, potentially fatal, multisystem adverse drug reaction characterized by skin rash, fever, hematological abnormalities, and lymphadenopathy with involvement of several internal organs. We report the case of a woman who developed DRESS syndrome with a generalized maculopapular rash, eosinophilia, dyspnea, bilateral cervical lymphadenopathy, and reactivation of Epstein-Barr virus (EBV) with liver damage 3 weeks after administration of strontium ranelate for postmenopausal osteoporosis. Approximately 6 months after total remission of cutaneous symptoms, the patient developed autoimmune hepatitis. This case confirms that strontium ranelate should be considered as a possible factor in the etiopathology of DRESS syndrome as well as in the subsequent development of autoimmune hepatitis. The possibility of developing autoimmune hepatitis as a part of DRESS syndrome related to strontium ranelate use can occur months after the acute episode.

The nasal ala, represents by nature, an anatomical part of the body unique for its characteristics. Unfortunately the nasal ala is often interested by traumas and by cancers whose treatment can determine an all - thickness amputation. In such cases the reconstruction is extremely engaging from a technical point of view, since it is necessary to recreate a satisfying aesthetical structure and to make a free air flow. We present the clinical case of a nasal ala major substance loss, due to a cancer, that has been treated by employing the new Mutaf Triangular Flap.

Because of the tendency of lentigo maligna (LM) for subclinical extension, staged excisions with margin control achieve lower recurrence rates than conventional wide local excision (0-9.5% vs 8-20%). However, these surgical techniques are limited by their requirement in time, costs and training.

Naevi typically involute after the fourth decade of life and are rare in the elderly. However, the rate at which naevi disappear with age varies greatly with some individuals still having large numbers of naevi in late middle age. A small subset of compound naevi in adolescence exhibits a peripheral rim of small brown clods. These naevi enlarge symmetrically with time, accompanied by a progressive development of reticular pattern until the disappearance of the peripheral clods that indicates their growth stabilization. On the other hand, a melanocytic lesion that shows a growth after the age of 30 should raise the doubt of being a melanoma and should thereafter be considered as candidate for excision. In a clinical setting, common behaviour is to excise a melanocytic lesion that shows growing parameters (like a peripheral rim of clods) after 35 years old.

Prurigo nodularis (PN) is a debilitating chronic disease characterized by intense itching and excoriated hyperkeratotic nodules distributed on the trunk and extremities, especially the extensor surfaces. The pathophysiology includes complex and not yet well-understood mechanisms involving inflammation and dysregulation of the nervous system. Currently, there are no approved therapies by the Food and Drug Administration (FDA) and the few treatment approaches for this condition are often ineffective and related to severe side effects. An emerging therapeutic option is dupilumab, a monoclonal antibody for adults and adolescents with moderate-to-severe atopic dermatitis, that inhibits interleukin-4 receptor alpha subunit (IL4-Rα) and the signaling pathways activated by interleukin (IL)-4 and IL-13. These cytokines seem to be involved in the development and perpetuation of PN and other type-2 inflammation diseases. Data on this topic are limited, but the emergent positive effects of this drug, reported in the literature and summarized in this review, suggest that it can be a safe and efficient therapy in PN.

Adamantiades-Behçet disease (ABD) is a systemic disease with vasculitis, characterized by recurrent oral aphthosis and ocular, cutaneous, articular, vascular, cardiopulmonary manifestations and it is mainly found in the territories of the antique "silk road". ABD pathogenesis remains unknown although genetic, infectious and environmental factors seem to be implicated in the development of the disease, which is considered an auto-inflammatory condition. COVID-19 infection can present some symptoms, in particular at the level of oral and pulmonary mucosa, which require a differential diagnosis with ABD. Furthermore, the immunological alterations of this disease, and the drugs used for its treatment could influence the infection by COVID-19, and its clinical evolution. Nevertheless, vaccination anti-COVID-19 is recommended in ABD patients. The most commonly used diagnostic criteria for ABD are those established in 2014 by the International Team for the Revision of the International Criteria for BD (ITR-ICBD). Furthermore, criteria for disease severity according to the Overall Damage Index of Behçet's Syndrome (BODI) have recently been proposed in order to quantify the severity of the disease as well as the evolution during follow-up. In ABD patients it is mandatory to investigate on the presence of active/latent tuberculosis, because of the common organ involvement, such as eyes and bowel. ABD has a high morbidity and low mortality, sometimes linked to the rupture of an arterial aneurysm and/or neurological complications. This article is based on a general review on ABD ranging from the history of ABD to possible causes and clinical manifestations. A specific section has been dedicated to the COVID-19 pandemic.

Metabolomic analysis has proven to be a useful tool in biomarker discovery and the molecular classification of cancers. In order to find new biomarkers, and to better understand its pathological behavior, bladder cancer also has been studied using a metabolomics approach. In this article, we review the literature on metabolomic studies of bladder cancer, focusing on the different available samples (urine, blood, tissue samples) used to perform the studies and their relative findings. Moreover, the multi-omic approach in bladder cancer research has found novel insights into its metabolic behavior, providing excellent start-points for new diagnostic and therapeutic strategies. Metabolomics data analysis can lead to the discovery of a “signature pathway” associated with the progression of bladder cancer; this aspect could be potentially valuable in predictions of clinical outcomes and the introduction of new treatments. However, further studies are needed to give stronger evidence and to make these tools feasible for use in clinical practice.

Background Epidemiologic data suggest an increased risk of melanoma (MM) and non-melanoma skin cancer (NMSC) in persons with intense recreational sun-exposure such as marathon runners or surfers. Up to data little is known about the sun-exposure habits, sun-protection behaviours and risk factors for MM and NMSC among sailors. Objective The objective of this prospective, cross-sectional study was to investigate the sun-exposure and sun-protective habits and risk factors for skin cancer among sailors attending the 50° edition of Barcolana, the largest sailing race in of the world, which took place in October 2018 in Trieste, Italy as an integrative component of a public sun-prevention campaign. Methods The study consisted of 2 parts: (i) a self-administered questionnaire focusing on sun-exposure and protective habits and (ii) a free skin examination carried out by volunteer dermatologists. Participation was optional and anonymous, and open to visitors and sailors attending the event. Results Overall, 431 (52.4%) sailors and 391 (47.6%) visitors responded to the questionnaire, while a total of 437 individuals including 189 (43.3%) sailors and 248 (56.6%) visitors participated in the skin examination group. The majority of sailors reported a past history of severe sunburns (20.2%), applied sunscreen never (14.4%) to sometimes (45.7%) or only once daily (59%) on the face (55%) and shoulders (26%). Moreover, 14% of sailors had a personal history of non-melanoma skin cancer (NMSC). During the dermatological examination, suspicious lesions for skin cancer (including MM and NMSC) were identified in 37% of the sailors. Conclusion Our findings support the need to develop and promote primary and secondary prevention strategies to improve the sun-exposure and sun-protective habits among sailors.

We report the first registered cases of cutaneous adverse reactions in North-East Italy after the m-RNA COVID-19 vaccine Comirnaty®-BioNTech/Pfizer, During January 2021, in the public health jurisdiction of Trieste, a total of 19,485 individuals have been vaccinated: 13,266 (68.08%) first doses and 6,219 (31.92%) completed cycles of two doses. In this population, 266 (1.36%) adverse reactions have been reported to the Pharmacovigilance Service. Notably, one or more cutaneous adverse effects were present in 44 people, accounting for 0.22% of all vaccinated individuals and 16.54% of communicated adverse effects. The reactions included both those at the injection site and more extensive manifestations (Table 1).

Opinion statementRecently introduced systemic therapies for locally advanced and metastatic non-melanoma skin cancers (NMSCs) are paving the way for neoadjuvant approach. Although none of the therapeutic options has currently gained indication in this setting, neoadjuvant approach for NMSCs is an open field and we are likely to see huge developments in the near future. Targeted therapy with sonic hedgehog pathway inhibitors is very effective in locally advanced or multiple basal cell carcinomas while immunotherapy with immune checkpoint inhibitors appears to be promising for advanced cutaneous squamous cell carcinoma and Merkel cell carcinoma. To date, targeted therapy and immunotherapy represent the frontiers in NMSC therapeutic management and, according to recent studies, good results can be achieved.

We present two patients with stage IV melanoma, the first with BRAF wild-type melanoma with multiple visceral metastases treated with immunotherapy (pembrolizumab) and the second with BRAFV600E melanoma with subcutaneous and lymph nodes metastasis treated with BRAF and MEK-inhibitors (dabrafenib/trametinib). Already after the second cycle of immunotherapy, the first patient developed a diffuse regression of nevi, perceptible only with the use of dermoscopy and 3 months later a clinically evident poliosis of the eyebrows. The second patient, treated with dabrafenib/trametinib, developed small areas of leukoderma on his chest and white halos around nevi with a dermoscopic globular or structureless pattern. Both observations are suggestive for an immune reaction against melanocytic cells, which is further supported by the complete response to systemic therapy in both patients. It has been demonstrated that the development of vitiligo-like depigmentation during immunotherapy is associated with a better prognosis; in our patient, the phenomenon of poliosis appeared much later than the dermoscopic presence of regression among his nevi, suggesting that the latter may be an early sign (along with vitiligo-like phenomena) of good response to immunotherapy. On the other hand, the development of halo nevi and leukoderma during treatment with BRAF/MEK-inhibitors, suggests that not only immunotherapy but also targeted therapy may induce an immunologic response against melanoma and nevi, again indicative of a favorable prognosis. More data are needed to confirm these findings; however, they indicate that dermatologists should be involved in the follow-up of patients with melanoma, both in studies and clinical practice.

Background: Basal cell carcinoma (BCC) and dermal nevi located on the face can easily be confused on clinical examination. Little is known about the different preferential localizations of these entities, and a systematic analysis of dermatoscopic features for differential diagnosis is lacking. Methods: Clinical and dermatoscopic images of BCCs and dermal nevi were retrospectively evaluated to study their relation to various face anatomical areas, BCC histotype, classic and nonclassic dermatoscopic BCC criteria, as well as typical dermatoscopic criteria for dermal nevi. Results: We examined 118 BCCs and 77 dermal nevi, all having histopathological confirmation. BCCs were most frequently located on the lateral side of the forehead (12.7%), nasal dorsum (10.2%) and nasal ala (9.3%), while dermal nevi were found predominantly on the buccal area (11.8%), scalp (11.8%), and perioral region (10.8%). The prevalent dermatoscopic criteria for BCC were the classic arborizing vessels (94.1%) and arborizing microvessels (89%). The most common BCC histotype on the face was sclerodermiform (47.5%), followed by nodular (28%) and superficial (24.6%). Conclusions: This study shows that BCCs are preferentially located on the lateral side of the forehead, nasal dorsum and nasal ala, while dermal nevi of the face are preponderantly located on the buccal area, scalp, and perioral region. The dermatoscopic features confirmed the frequency of classic and nonclassic criteria for BCCs already demonstrated in other studies. No significant site-specific features were observed for either BCCs or dermal nevi.

Dermatoscopy is a non-invasive tool that increases the accuracy of non melanoma skin cancer (NMSC) diagnosis. Dermoscopic features of basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) have been already described, however criteria of these skin cancers, according to different anatomical locations of face and scalp have not been described before.

Bone is the fourth most common site of melanoma metastasis after lung, liver, and brain. Melanoma bone metastases typically occur in patients who already have widespread metastases in other organs. Current available approaches for bone metastases from melanoma include chemotherapy, radiotherapy, biological therapy, combination therapy, and surgery. In this narrative review, we describe the management of patients affected by melanoma bone metastases, discussing the diagnostic and treatment approaches as well as their impact on survival and quality of life. Despite the fact that clinical and surgical trials will be required to determine the most appropriate treatment, we do expect a newer and more important role of multidisciplinary approach in the management of melanoma patients with bone metastases in the next future.

Background Among the various types of basal cell carcinoma, the sclerodermiform variant has a high risk of recurrence and local invasiveness. A systematic description of the dermatoscopic features associated with specific body localization is lacking.Objectives To describe the clinical and dermoscopic features of sclerodermiform basal cell carcinoma (BCC) according to localization in the body confronting with superficial and nodular types.Methods Clinical and dermoscopic images of sclerodermiform, nodular and superficial BCCs were retrospectively evaluated to study the location in the various body districts, maximum diameter, clinical appearance of the lesion, features of edges and presence or absence of specific dermatoscopic criteria of BCCs.Results We examined 291 histopathologically proven BCCs showing that in nodular BCCs, classical arborizing vessels were more frequently found in the body macro-area (trunk and limbs; n = 46, 97.9%) than in the head/neck area (n = 43, 82.7%); within sclerodermiform BCCs, short arborizing vessels were found more frequently in the head/neck district (n = 35, 49.3%) than in the body (n = 6, 23.1%; P-value 0.02); within nodular BCCs, multiple blue-grey dots and globules were more frequently found on the trunk (n = 23, 48.9%) than in the head/neck district (n = 12, 23.1%; P-value 0.01). In sclerodermiform BCCs, ulceration was found more frequently in the head/neck district (n = 38, 53.5%) than in the body (n = 4, 15.4%; P-value > 0.01), and in superficial BCCs, ulceration was found more frequently in the head/neck district (n = 5, 38.5%) than in the body (n = 8, 9.8%; P-value 0.02).Conclusion Our study shows that superficial BCC are found frequently in the head/neck district dermoscopically characterized by ulceration and arborizing vessels; nodular BCCs are more frequently found in the body than in the head/neck district, and the dermoscopic pattern is characterized by the combination of three features: (i) classical arborizing vessels, (ii) multiple blue-grey dots and (iii) globules. Instead, sclerodermiform BCC is preferentially located in areas at high-moderate risk of recurrence; if pink-white areas and/or fine arborizing vessels are seen, clinicians should consider this diagnosis. Furthermore, location-specific dermatoscopic criteria have been described.

Lyme disease is a tick-borne illness, which is typically caused by Borrelia Burgdoferi. Over time, a typical Borreliosis skin reaction takes shape, i.e. the formation of an annular erythema that tends to expand centrifugally with erythematous edges whose diameter can reach up to 20 cm. The symptoms of Lyme disease are not only cutaneous but there may be a systemic involvement. Obviously, this disease can also affect pregnant women and for this reason this review aims to summarize the main ways of treatment to avoid worsening of the clinical condition in the mother and an eventual, albeit rare, involvement of the fetus.

Two round tables involving experts were organized in order to reach a consensus on the management of patients with actinic keratosis (AK). In the first, seven clinical questions were selected and analyzed by a systematic literature review, using a Population, Intervention, Control, and Outcomes framework; in the second, the experts discussed relevant evidences and a consensus statement for each question was developed. Consensus was reached among experts on how to best treat AK patients with respect to different clinical scenarios and special populations. Lesion-directed treatments are preferred in patients with few AKs. Patients with multiple AKs are challenging, with more than one treatment usually needed to achieve complete lesion clearance or a high lesion response rate, therapy should be personalized, based on previous treatments, patient, and lesion characteristics. Methyl aminolevulinate-PDT, DL (day light) PDT, and imiquimod cream were demonstrated to have the lowest percentage of new AKs after post treatment follow-up. For IMQ 5% and 3.75%, a higher intensity of skin reactions is associated with higher efficacy. Photodynamic therapy (PDT) is the most studied treatment for AKs on the arms. Regular sunscreen use helps preventing new AKs. Oral nicotinamide 500 mg twice daily, systemic retinoids and regular sunscreen use were demonstrated to reduce the number of new squamous cell carcinomas in patients with AKs. Limited evidence is available for the treatment of AKs in organ transplant recipients. There is no evidence in favor or against the use of any of the available treatments in patients suffering from hematological cancer.

Actinic keratosis (AK) is a very common skin disease caused by chronic sun damage, which in 75% of cases arises on chronically sun-exposed areas, such as face, scalp, neck, hands, and forearms. AKs must be considered an early squamous cell carcinoma (SCC) for their probable progression into invasive SCC. For this reason, all AK should be treated, and clinical follow-up is recommended. The aims of treatment are: (i) to clinically eradicate evident and subclinical lesions, (ii) to prevent their evolution into SCC, and (iii) to reduce the number of relapses. Among available treatments, it is possible to distinguish lesion-directed therapies and field-directed therapies. Lesion-directed treatments include: (i) cryotherapy; (ii) laser therapy; (iii) surgery; and (iv) curettage. Whereas, field-directed treatments are: (i) 5-fluorouracil (5-FU); (ii) diclofenac 3% gel; (iii) chemical peeling; (iv) imiquimod; and (v) photodynamic therapy (PDT). Prevention plays an important role in the treatment of AKs, and it is based on the continuous use of sunscreen and protective clothing. This review shows different types of available treatments and describes the characteristics and benefits of each medication, underlining the best choice.

The term keratinocyte skin cancer (KC) stands as an umbrella for different stages within the progression of cutaneous squamous cell carcinoma (cSCC). 1‐2 Its earliest form is named actinic keratosis (AK), while for the in‐situ form different synonyms, namely intraepidermal carcinoma (IEC), Bowen's Diseases (BD) and cutaneous squamous cell carcinoma in situ [cSCC(Tis)] or intraepithelial squamous cell carcinoma (iSCC) are used.3 Instead, cSCC is histopathologically classified into well, moderately and poorly differentiated subtypes.

Locally advanced basal cell carcinoma (laBCC) represents an uncommon, difficult to treat form of skin cancer (1,2). The approval of hedgehog inhibitor (HHI) vismodegib in 2012 opened a novel therapeutic option (2-10). "Drug holidays" have been proposed to increase patients' compliance and adherence which is poor due to the high frequency of adverse effects (AE's) of HHI (3-5), however, up to date, the effect of dose reduction during HHI treatment has not been reported. Herein we report the data of a single center's experience in dose adjustment in 13 patients with laBCC treated with vismodegib.

Dermatoscopy is a noninvasive diagnostic technique that was used mostly for diagnosing pigmented lesions, [1] , [2] but more recently, it has been employed in the diagnosis of infectious and inflammatory skin lesions, also known as entomodermoscopy and inflammoscopy, 3 as well as for hair 4 and scalp disorders, called trichoscopy. 5 The initial name of epiluminescence microscopy has evolved into dermatoscopy and dermoscopy but not without controversy.

The importance of dermoscopy for diagnosing lentigo maligna melanoma (LMM) is well known. More recently, dermoscopy has been proposed as a useful tool also for the treatment choice and monitoring. Herein we present an 87 year-old woman, who was successfully treated with imiquimod 5% cream after post-surgical persistence of residual LMM and for whom dermoscopy was helpful to assist diagnosis, assess tumor persistence after surgery and its response to topical treatment with imiquimod.

Leukemia cutis (LC) is described as cutaneous infiltration by neoplastic leukocytes into the epidermidis, dermis, or subcutis, resulting in clinically various skin lesions. When the infiltrate is characterized by neoplastic granulocytic precursors, LC is defined as granulocytic sarcoma. Multiple, erythematous, and infiltrated papules and nodules localized on the legs, arms, and trunk are the most common clinical presentation. Here we report a case of granulocytic sarcoma in a patient with a previous diagnosis of acute myeloid leukemia currently in hematological remission.
