The increasing use of dermoscopy in preoperative diagnosis of melanocytic skin neoplasms is impacting on routine histopathology to a relevant extent. We herein present the dermoscopic-pathologic features of 6 cases of histopathologically controversial melanocytic skin neoplasms. By illustrating these cases, we emphasize at least 3 different fields of interest for a combined (clinico-)dermoscopic-pathologic diagnostic approach, namely, information about the evolution of lesions; detection of gross sampling errors; definition of peculiar clinicopathologic entities. The theoretic and practical aspects of a close interaction among dermoscopists and histopathologists are itemized in detail.

SMARCB1-deficient malignant melanocytic uveal tumours: a new neural crest-derived tumour entity with SMARCB1-related germline predisposition.

Rhabdoid tumours (RT) are an aggressive malignancy affecting <2-year-old infants, characterised by biallelic loss-of-function alterations in SWI/SNF-related BAF chromatin remodelling complex subunit B1 (SMARCB1) in nearly all cases. Germline SMARCB1 alterations are found in ~30% of patients and define the RT Predisposition Syndrome type 1 (RTPS1). Uveal melanoma (UVM), the most common primary intraocular cancer in adults, does not harbour SMARCB1 alterations.

Primary vulvar carcinomas are rare and constitute a diverse group of neoplasms. These primary tumors are typically classified based on their presumed tissue of origin or histological characteristics. Among these, carcinomas of sweat gland origin are particularly significant.

Introduction: Recent findings show that visible light, particularly blue light, stimulates melanogenesis in human skin, though the underlying mechanisms remain debated. This study aimed to determine the cell damage threshold of non-ionizing blue light on keratinocytes while preserving their ability to stimulate melanogenesis.
Methods: Human keratinocytes (N = 3) and melanocytes (N = 3) were isolated from skin samples of varying Fitzpatrick skin phototypes and irradiated with blue light (λpeak = 457 nm) and UVA light (λpeak = 385 nm).
Senolytic Targeting of Anti-Apoptotic Bcl Family Increases Cell Death in UV-Irradiated Senescent Melanocytes: Search for Senolytics.

Senescent melanocytes have been suggested to play a role in the development of ageing-associated pigmentary changes and skin ageing. Here, we assessed the senolytic capacity of recognised senolytic chemicals and natural compounds in UV-irradiated senescent melanocytes. Among the tested agents, only ABT-737 and ABT-263 showed a significant reduction in the number of SA-β-Gal-positive senescent melanocytes and in the expressions of p16 and p21.

Giant congenital melanocytic nevi are large pigmented premalignant lesions present at birth that have an associated risk of malignant transformation. Full-thickness excision of these lesions would be required to eliminate this risk. However, giant nevi can leave behind large defects that can be challenging to reconstruct.
