Dermatofibroma (DF) is a common benign fibrohistiocytic lesion which presents with a wide variety of clinicopathological features. Generally, the clinical diagnosis is easy, but differentiating it from other cutaneous tumors could be difficult in atypical cases and rare variants. We may find at least four different histopathological variants of DF; more than one of which may be present in a single tumor. Hemosiderotic DF is a variant composed of numerous small vessels, extravasated erythrocytes, and intra- and extracellular hemosiderotic deposits. The differential diagnosis may comprise melanoma as well as other melanocytic and nonmelanocytic tumors. We report the case of a 38-year-old man who presented with a hemosiderotic DF on the abdomen.
