Primary cutaneous NUT adnexal carcinoma: morphologic, genetic and methylation analysis of seven new cases with comparison to extracutaneous NUT carcinoma and NUTM1‐rearranged porocarcinoma

Histopathology, Volume 87, Issue 3, Page 375-387, September 2025.
Microscopic features of a NUTM1 adnexal carcinoma magnification. This neoplasm consisted of large, poorly demarcated tumors, sometimes ulcerated infiltrated the dermis and subcutaneous tissue (HPS ×10). The lesions were organized in strands, cords and larger solid nests of poorly differentiated cells characterized by enlarged, irregular nuclei (HPS ×20)

Radiotherapy and prognostic factors in adnexal carcinomas: A retrospective study of 657 patients from the French CARADERM network

Journal of the European Academy of Dermatology and Venereology, Volume 39, Issue 3, Page 586-593, March 2025.
Abstract Background Cutaneous adnexal carcinomas are a heterogeneous group of rare neoplasms. Surgical excision is the first‐line treatment in localized stage. The use and effectiveness of radiotherapy have not been thoroughly evaluated in these neoplasms.

Gene expression profiling in porocarcinoma indicates heterogeneous tumor development and substantiates poromas as precursor lesions

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 22, Issue 8, Page 1115-1124, August 2024.
Summary Background and objectives Malignant sweat gland tumors are rare, with the most common being eccrine porocarcinoma (EP). Approximately 18% of benign eccrine poroma (EPO) transit to EP. Previous research has provided first insights into the mutational landscape of EP. However, only few studies have performed gene expression analyses.
