research Dermoscopy of a Congenital Pigmented Lesion: A Case of Supernumerary Nipple
A 20-year-old man presented with a congenital pigmented lesion on his chest, identified as a supernumerary nipple (SNN) through dermoscopy. This developmental anomaly typically appears along the embryonic milk lines, often on the left side of the trunk. Dermoscopic examination revealed characteristic features such as a central whitish scar-like structure, cobblestone-like globules, and peripheral network-like structures, which are common in over 80-90% of SNN cases. These features help differentiate SNN from other conditions like dermatofibroma, melanocytic nevus, and pigmented basal cell carcinoma, preventing misdiagnosis and unnecessary procedures.
