Benign cellular fibrous histiocytoma in a rare location—A toe

A cellular fibrous histiocytoma (CFH) is a variant of fibrous histiocytomas with increased cellularity with a fascicular growth pattern and increased frequency to extend into the subcutis. CFH is a benign nodular growth with a high recurrence rate of 26%. It is regularly confused with dermatofibrosarcoma protuberans and leiomyosarcoma due to their morphological similarities, hence emphasizing the importance of proper diagnosis. In this article, we discuss the case of a 50-year-old male who presents with a recurrence of CFH 30 years post-excision. The 15mm lesion on the right fourth toe was previously diagnosed and excised as a granuloma, highlighting the error in misdiagnosis. In regard to the current case, a surgical excision was performed, and histopathology testing confirmed the diagnosis of CFH with no complication. To this date, there is no occurrence of a CFH on the foot reported in the literature.
