Hemosiderotic dermatofibroma: clinical and dermoscopic presentation mimicking melanoma.

Abstract

Background: Dermatofibromas are common benign skin neoplasms.

Main observations: The authors report the clinical, dermoscopic and histopathological features of a hemosiderotic dermatofibroma mimicking melanoma in an 85-year-old woman.

Conclusions: Atypical dermoscopic patterns may prove difficult to differentiate from melanocytic lesions, and because of its polymorphic, melanoma-like presentation, definite diagnosis of hemosiderotic dermatofibroma can be reached by histopathological examination.
