Extrapleural Solitary Fibrous Tumor of the Foot A Case Report.

Abstract

Solitary fibrous tumors are uncommon mesenchymal neoplasms that were initially described as pleural tumors, but in recent years, numerous extrapleural sites have been reported. A solitary fibrous tumor is characterized as a circumscribed, painless mass with a patternless growth pattern, positive CD34 spindle-shaped cells, bcl-2, and dense keloidal collagen with areas of hypercellularity and hypocellularity. This case report describes a 55-year-old male veteran who presented with a rare manifestation of an extrapleural solitary fibrous tumor of the medial right hallux. Microscopic and immunohistochemical findings were consistent with the previously documented characteristics of solitary fibrous tumors. Complete surgical excision of the tumor is the treatment of choice.
