Dermoscopy in Merkel cell carcinoma: a case report

Abstract

Merkel cell carcinoma (MCC) is a rare malignant and primary neuroendocrine carcinoma with several known risk factors. Early diagnosis and aggressive treatment are critical. We report the case of an 82-year old woman with a Merkel cell carcinoma on the face. Clinical and histopathological features are presented. In addition, dermoscopic features and the differential diagnosis of this rare tumor are discussed. Although nodules with atypical dermoscopic vascular pattern and milky-red areas will end up being excised, this report adds more clues to the rarely described dermoscopic morphologic presentation of MCC.
