Abstract	Cutaneous pseudolymphomas are a wide group of diseases mimicking cutaneous lymphoma. They comprise several skin conditions with different etiopathogenesis, clinical-pathological features, and prognosis, which may occur in the absence of an identifiable trigger factor or after administration of medications or vaccinations, tattoos, infections, or arthropod bites. They present with different manifestations: from solitary to regionally clustered lesions, up to generalized distribution and, in rare cases, erythroderma. They persist variably, from weeks to years, and resolve spontaneously or after antibiotics, but may recur in some cases. CD30+ T-cell pseudolymphomas are characterized by the presence of large, activated lymphoid cells, generally in response to viral infections, arthropod assault reactions, and drug eruptions. Stenotrophomonas maltophilia is a ubiquitous Gram-negative bacillus responsible for opportunistic infections in immunocompromised patients. Infection of intact skin in immunocompetent patients is particularly rare. Here, we report a case of a man presenting an isolated nodule histopathologically mimicking a primary cutaneous CD30+ T-cell lymphoproliferative disorder.

Abstract	Importance: Based on early studies, prurigo pigmentosa (PP) was considered a rare inflammatory dermatosis affecting primarily Asian individuals. However, several case reports subsequently showed that the disease is not restricted to those of Asian origin. Large studies on PP in central European individuals, on the other hand, are missing. Objective: To increase awareness of PP by describing the clinical, histopathological, and immunohistochemical features in central European individuals. Design, setting, and participants: This observational, retrospective case series analyzed clinicopathological features of 20 central European patients diagnosed with PP. Data collection was performed by means of archive material, including physician's letters, clinical photographs, and histopathological records, at the Department of Dermatology at the Medical University of Graz in Austria from January 1998 to January 2022. Main outcomes and measures: Demographic, clinical, histopathological, and immunohistochemical characteristics for patients diagnosed with PP were recorded. Results: Of the 20 patients included, 15 (75%) were female, and the mean (range) age was 24.1 (15-51) years. The study cohort consisted entirely of European patients. The most common site of involvement of PP was the breast, followed by the neck and back. Other involved clinical sites were the abdomen, shoulders, face, head, axillae, arms, and genital region and groin. Clinically, lesions were characterized by a symmetric pattern in 90% (n = 18) of all cases. Marked hyperpigmentation was observed only in 25% (n = 5) of patients. In some cases, triggers such as malnutrition, long-term pressure, and friction were noted. Histologic findings revealed presence of neutrophils in all cases and necrotic keratinocytes in 67% (n = 16) of cases. Immunohistochemistry results showed predominance of CD8+ lymphocytes in the epidermis, as well as the presence of plasmacytoid dendritic cells and myeloid cell nuclear differentiation antigen-positive neutrophil precursors. Conclusions and relevance: This case series found that most clinical features observed in Asian patients were also observed in central European patients, but hyperpigmentation was primarily mild to moderate. Histopathological features were similar to those reported in the literature with the additional presence of myeloid cell nuclear differentiation antigen-positive precursor neutrophils. These results expand previous knowledge about PP in central European individuals.

Abstract	Diffuse (generalized) plane xanthoma is a rare normolipemic xanthomatosis, frequently associated with multiple myeloma and monoclonal gammopathy. Its clinical presentation is well described, and in most cases, clinical suspicion is immediate. Rarely, it can clinically present with a diffuse and uniform yellowish discoloration, and in this context, several investigations are required to identify the correct diagnosis. We describe a case characterized by progressive diffuse yellow-orange discoloration lasting about 3 years and classified as carotenoderma in which reflectance confocal microscopy addressed the diagnosis and drove the correct selection of the biopsy site. Definitive diagnosis of diffuse (generalized) plane xanthoma was confirmed later by histological examination.

Abstract	Background: Brooke-Spiegler syndrome is a rare autosomal dominant disorder characterized by the continuous development of multiple benign skin appendage tumors. It is treated usually by repeated standard surgery. Here, we present a case study where electrochemotherapy (ECT) with bleomycin was used as an effective alternative approach in treating advanced dermal cylindromatosis of the head and neck in a patient with Brooke-Spiegler syndrome. Patients and methods: A 45-year-old woman presented with multiple recurrent dermal cylindroma lesions on her scalp. Previous treatment consisted of several surgical excisions that resulted in psychological deterioration due to the formation of numerous scars and extensive alopecic areas. ECT was offered to provide tumor removal and disease control and to improve the patient's quality of life. Results: The treatment was well tolerated, and a significant reduction in neoplastic tissue was achieved. Importantly, scalp skin condition significantly improved, regaining a fair follicular density on the margins. Conclusion: This report suggests the feasibility of bleomycin ECT as a less invasive alternative option for controlling multiple scalp cylindroma lesions with cosmetically acceptable results, and improving quality of life.

Abstract	The endocannabinoid system regulates physiological processes, and the modulation of endogenous endocannabinoid (eCB) levels is an attractive tool to contrast the development of pathological skin conditions including cancers. Inhibiting FAAH (fatty acid amide hydrolase), the degradation enzyme of the endocannabinoid anandamide (AEA) leads to the increase in AEA levels, thus enhancing its biological effects. Here, we evaluated the anticancer property of the FAAH inhibitor URB597, investigating its potential to counteract epithelial-to-mesenchymal transition (EMT), a process crucially involved in tumor progression. The effects of the compound were determined in primary human keratinocytes, ex vivo skin explants, and the squamous carcinoma cell line A431. Our results demonstrate that URB597 is able to hinder the EMT process by downregulating mesenchymal markers and reducing migratory potential. These effects are associated with the dampening of the AKT/STAT3 signal pathways and reduced release of pro-inflammatory cytokines and tumorigenic lipid species. The ability of URB597 to contrast the EMT process provides insight into effective approaches that may also include the use of FAAH inhibitors for the treatment of skin cancers.

Abstract	Introduction: The term "atypical melanocytic nevus" (AMN) is used as a synonym for dysplastic nevus (DN) in clinical practice. Although the criteria for diagnosis of AMN/DN by the Agency for Research on Cancer helps to differentiate AMN/DN from common acquired nevi, they do not have high degrees of specificity, as they are similar to those used for the diagnosis of melanoma. Objectives: In this retrospective study we evaluated the correlation and diagnostic concordance of dermoscopy, confocal microscopy, and histological examination in 50 AMN. Methods: A graded scale was used to compare histological examination with dermoscopy and confocal microscopy. Low magnification histological images of only the central part of lesions were examined. This allowed histological diagnoses based almost exclusively on architectural criteria instead of simultaneously architectural and cytological, as in the global histological examination. Results: Our data demonstrate that the diagnostic accuracy of dermoscopy and confocal microscopy diagnosis of the clinical aspects of AMN/DN as nevi or melanomas tends to be equivalent, being fair for nevi and excellent for melanomas. The total percentage of AMN suggested that the accuracy of confocal microscopy in the diagnosis of melanoma (86.7%) is greater than that of dermoscopy (73.3%). Conclusions: This study demonstrated that diagnostic assessments of AMN/DN by dermoscopy and confocal microscopy are accurate and often coincide with those of histological examination and that their combined use helps to better manage and monitor these patients by facilitating early detection of melanomas and reducing unnecessary excisions of benign melanocytic lesions.
