[Benign desmoplastic fibroblastoma of the lower leg. A rare case].

Desmoplastic fibroblastoma ("collagenous fibroma") is a benign fibrous soft tissue tumor. We report a rare case of a "collagenous fibroma" located in the proximal lower leg in 56-year-old man. The clinical, radiological, and pathological-morphological findings are documented. The operative treatment was performed according to general principles of surgical management of benign soft tissue tumors.
