Atypical fibrous histiocytoma : Usually presents in younger patients, lacks prominent actinic changes and may have areas of classic dermatofibroma in the periphery of the tumor. Leiomyosarcoma : Usually positive for smooth muscle markers, such as smooth muscle myosin and desmin.

AFX carries a good prognosis overall. Recurrences typically occur within the first 3 years. Based on a review of 1500 published cases, the overall recurrence rate was 7.6%. Metastasis is rare, but when it occurs, the lymph nodes are often the first site of involvement.
