Desmoplastic Fibroblastoma of the Ankle: A Case Report of a Rare Localization and a Literature Review

Abstract

Introduction: Desmoplastic fibroblastoma is a rare, slow-growing benign soft tissue tumor. It has a wide anatomical distribution and mainly affects adult males. Fourteen percent of cases occur in the ankle or foot. Case Report: In this study, we report a rare location of desmoplastic fibroblastoma on the ankle of a 76-year-old female, discovered as a slowly growing mass. Discussion: Desmoplastic fibroblastoma is an anatomical and clinical entity. It appears macroscopically as a pseudocartilaginous structure and histologically as a stellate or spindle-shaped fibroblastic proliferation in a collagenous stroma. Conclusion: Desmoplastic fibroblastoma has anatomical specificities and should still be clearly distinguished from certain malignant tumors. Keywords: Ankle, benign tumor, fibroblastoma.
