Frequent PIK3CA-activating mutations in hidradenoma papilliferums

, 2017
Hidradenoma papilliferum (HP) is a benign epithelial tumor most commonly seen in the vulva. It is proposed to be derived from the anogenital mammary-like glands and is histologically very similar to the mammary intraductal papilloma (IP).

Novel and emerging skin carcinomas and adnexal tumours

Histopathology, EarlyView.
The present review aims to provide an overview of the main emerging skin epithelial tumours, with particular emphasis on salivary gland analogue sweat gland tumours and poorly differentiated carcinomas. Epidermal and adnexal tumours of the skin constitute a complex and heterogeneous group of neoplasms, with distinct morphology and behaviour.

Poroid Hidradenoma: Case Report and Comprehensive Review of the Literature

Case Reports in Dermatology, 2023
Poroid hidradenoma (PH) is a rare benign adnexal tumor of eccrine differentiation. It is the rarest of the four described variants of poroid neoplasms. PHs characteristically share a hybrid of the architectural features of the hidradenoma, namely, tumor ...

S1 guideline sweat gland carcinoma

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 24, Issue 9, Page e1356-e1385, September 2026.
Summary The current classification of sweat gland carcinomas is based on histomorphological characteristics and distinguishes between more than 20 entities. Most patients are older, but some subtypes also affect middle‐aged and younger patients. The majority of tumors arise de novo. Sweat gland carcinomas have nonspecific clinical features.

A Multifaceted Holistic Review of the Literature on Scar Dermatoses

International Wound Journal, Volume 23, Issue 5, May 2026.
ABSTRACT Many cutaneous diseases originate or manifest in scars. Scars are areas of compromised skin, which renders them a vulnerable cutaneous district for diseases to develop. The pathophysiology explaining why some dermatoses grow in scars is not yet thoroughly explored. The present study reviews the present literature on scar dermatoses.

Robustness of a convolutional neural network trained on dermoscopic images and challenged with close‐up images

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 24, Issue 4, Page 504-513, April 2026.
Summary Background and Objectives Deep learning‐convolutional neural networks (DL‐CNNs) have demonstrated high diagnostic accuracy within the domain of dermoscopy. However, many clinical settings lack dermoscopic devices, requiring reliance on close‐up images. This study evaluates the robustness of a DL‐CNN trained on dermoscopic images when challenged
