Dermoscopy of squamoid eccrine ductal carcinoma: an aid for early diagnosis

Márcio Martins Lobo-Jardim et al. An Bras Dermatol. 2018 Nov/Dec.

Abstract

Squamoid eccrine ductal carcinoma is a cutaneous malignancy that originates from the eccrine sweat gland. A 76-year-old woman presented with an asymptomatic papule on her nose that had been present for one year. Dermoscopy showed pseudocysts, irregular linear crown vessels, and yellowish-brown globules surrounded by white halos. This is the first dermoscopic description of squamoid eccrine ductal carcinoma. Studies with more cases are needed to confirm the dermoscopic characterization of this tumor.
