Abstract |
Dermatofibroma(benign fibrous histiocytoma) is a relatively common fibrohistiocytic tumor. It has a variety of histologic variants
and the diagnosis may be difficult in atypical or rare cases. Hemosiderotic dermatofibroma is an uncommon pathologic subtype
of dermatofibroma. Histopathologically, it is characterized by widespread deposition of intra- and extracellular hemosiderin,
numerous small vessels and extravasated erythrocytes, in addition to the typical features of classic dermatofibroma. It has been
recognized as a precursor lesion for the development of aneurysmal dermatofibroma. This tumor should be differentiated from
other histologic variants of dermatofibroma and fibrohistiocytic tumors with variable grade of malignancy. Herein, we represent a
case of hemosiderotic dermatofibroma occurring in a 32-year-old male. |
