Overview
Hemosiderotic dermatofibroma represents a rare subtype of dermatofibroma, characterized by the presence of numerous small vessels, siderophages, and hemosiderin deposits, which can have a wider variety of clinical manifestations. Atrophic dermatofibroma, another rare variant, presents as an atrophic plaque of varying colors. We report a case of a 27-year-old woman with a slow-growing, atrophic bluish-brown plaque on her right lower leg that developed after minor trauma. Histopathological examination of the biopsy revealed an intradermal tumor with hemosiderin deposits, histiocytes, and giant Touton cells.
The diagnosis of hemosiderotic dermatofibroma was confirmed by immunohistochemical staining, demonstrating positivity for Factor XIIIa and negativity for CD34. Due to the progressive nature of the lesion, a complete surgical excision was recommended, but the patient refused. This case illustrates the rare coexistence of hemosiderotic and atrophic features in a dermatofibroma, highlighting the importance of a comprehensive diagnostic approach.
