TL;DR

A 44-year-old man with a burning, swollen left nipple was diagnosed with a rare condition called SMOLD through biopsy after other methods were inconclusive.

Contribution

This case report adds a rare male instance of SMOLD to the clinical literature with detailed clinical, dermoscopic, and histopathological analysis.

Findings

A biopsy confirmed squamous metaplasia of lactiferous ducts in a male patient.

Dermoscopic findings were inconclusive, highlighting the need for histopathological confirmation.

The patient experienced persistent symptoms despite initial empirical treatment.

Abstract

We present the case of a 44-year-old male patient who presented to a dermatology outpatient clinic due to an asymmetric swelling of the left nipple. The patient reported a burning sensation within the area, persisting for approximately six months. Due to the inconclusive dermoscopic findings and lack of improvement following empirical treatment, a biopsy was performed. Histopathological examination revealed keratinizing squamous metaplasia of the lactiferous ducts (SMOLD).
