Abstract

We report a rare clinical case of hemosiderotic dermatofibroma in a 36-year-old female patient. The main dermatoscopic finding was represented by homogeneous blue-gray pigmentation. The aim of this report is to demonstrate the rarity of the lesion and the dermatoscopic importance it assumes by sharing a blue-gray homogeneous pattern with other benign and malignant lesions.
