Atypical Fibroxanthoma is a rare cutaneous tumour first described in 1963 by Elson Helwig. It has been related to ultraviolet-induced damage and most frequently occurs in sun damaged head and neck skin. Other risk factors include trauma, burns, irradiation, xeroderma pigmentosum, and organ transplantation.

May have xanthoma cells. Mitotic figures rare but may be atypical. Mitotic figures frequent, many of which are atypical. The behavior of atypical fibroxanthoma is benign, if strict diagnostic criteria are applied. Tumors with similar pathologic features but deep subcutaneous invasion, necrosis, and/or lymphovascular or perineural invasion are thought to be associated with adverse outcome and are better regarded as pleomorphic dermal sarcoma or undifferentiated pleomorphic sarcoma of skin. Atypical fibroxanthomas and pleomorphic dermal sarcomas are tumors arising in sun-damaged skin of elderly patients. They have differing prognoses and are currently distinguished using histological criteria, such as invasion of deeper tissue structures, necrosis and lymphovascular or perineural invasion.

Abstract.

Atypical fibroxanthoma often appears in areas that have received excessive sun exposure, usually around the scalp, ears, nose, cheeks, and back of the neck, or in areas where individuals may have previously received radiotherapy treatment. They have also been reported to occur on the trunk, extremities, and in sun-protected areas.
