Hemosiderotic dermatofibroma: clinical and dermoscopic presentation mimicking melanoma

[摘要] 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.
