Dermatofibroma (DF) is a common, benign fibrohistiocytic tumor with unknown pathogenesis. There are multiple uncommon histologic variants of DF reported in literature, one of which is hemosiderotic DF. It can variably present as a pigmented papule or nodule commonly located on the lower extremities. Hemosiderotic DF remains to be underreported in the Philippines despite the widely available dermatopathology services in the country.
