A Case of Atypical Fibroxanthoma / 대한피부과학회지

Atypical fibroxanthoma(AFX) is a pleomorphic spindle cell neoplasm of the dermis, which is a clinically benign reactive lesion despite apparently malignant histologic features. We describe a 38-year-old woman with AFX developed on the right popliteal area. The lesion was superficially located and composed of densely cellular, pleomorphic spindle cells and several bizarre multinucleated giant cells. It is uncommon that AFX developes on the lower leg in the middle age.
