Desmoplastic Fibroblastoma (Collagenous Fibroma) of the Foot: A Case Report of a Rare Benign Tumor in an Atypical Patient

J Am Podiatr Med Assoc. 2022 May-Jun;112(3):19-020. doi: 10.7547/19-020.


Desmoplastic fibroblastoma (collagenous fibroma) is a rare benign soft-tissue tumor. Often found in the subcutaneous and muscle tissue, it is slowly enlarging and generally not painful or invasive. The literature often describes the tumor to be found in the upper extremities, neck, and back. Full excision of the tumor is the treatment of choice, and the prognosis is generally favorable; there are no documented cases of recurrence after full excision. We present an atypical case of desmoplastic fibroblastoma found on the dorsum of the foot with a larger tumor present in a substantially younger patient than is typical.
