Hemosiderotic fibrolipomatous tumor: A poorly known entity

Hemosiderotic fibrohistiocytic lipomatous tumor (HFLT) is a rare and supposedly benign fibrolipomatous entity. Clinical and imaging features are not specific. So, histologic, immunohistochemical and molecular analyses are required for diagnosis. The clinic and pathologic aspects of this lesion are diversely reported. Moreover, its reactive or neoplastic origin is still under debate. This lesion should be treated by complete excision. It is mandatory to be aware of its tendency to harbor higher-grade lesions with aggressive outcome. We report a case of HFLT affecting the dorsum of the third right finger in a 52-year-old women, in order to describe histologic patterns of this tumor and to discuss the current literature regarding the etiopathogeny and the cytogenetic features of this rare entity.
