Subungual Onycholemmal Cysts: A Case Report

Case Reports in Dermatology, 2021
Subungual onycholemmal cysts (SOCs) are rare nail abnormalities. The clinical findings vary and include onychodystrophy, ridging, nail bed pigmentation, and thickening, but most often SOCs do not cause any symptoms and are accidental findings.

The Histopathologic Evaluation of Diagnostic Procedures in Nail Melanoma

Dermatology Practical & Conceptual, 2023
Introduction: The diagnostic delay in nail melanoma (NM) has been repeatedly emphasized. It may be related to both clinical misinterpretations and to errors in the bioptic procedure. Objectives: To assess the efficacy of histopathologic examination in

Paediatric Melanonychia: Diagnosis and Management

JEADV Clinical Practice, EarlyView.
ABSTRACT Longitudinal melanonychia (LM) in children presents unique diagnostic and management challenges that cannot be adequately addressed by applying adult‐based criteria. Unlike in adults, there are no validated clinical, dermoscopic or histopathologic criteria for predicting nail unit melanoma in the paediatric population.

Diagnostic Utility of PRAME Immunohistochemistry for Distinguishing Acral Melanoma From Acral Melanocytic Nevi

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Introduction Preferentially expressed antigen in melanoma (PRAME) immunohistochemistry helps distinguish non‐acral melanocytic lesions, but few studies have addressed its value in acral lesions. We aimed to identify an optimal PRAME cut‐off score to differentiate acral melanoma (AM) from acral melanocytic nevi (AMN).

AI‐assisted diagnosis of nail unit melanoma and melanonychia using a clinical deep learning model

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background and objectives Nail unit melanoma (NUM) is a rare but potentially fatal malignancy often misdiagnosed as melanonychia. Because biopsy may cause permanent nail dystrophy, accurate noninvasive diagnosis is essential. This study aimed to develop and validate an artificial intelligence model to distinguish NUM from benign melanonychia ...
