BACKGROUND Atypical fibroxanthoma (AFX) is an uncommon superficial fibrohistiocytic tumor. It was originally described as a low‐grade dermal tumor of atypical spindle cells, but this view has changed, and it is generally considered to be a tumor of intermediate malignant potential.

Atypical fibroxanthoma usually stains for CD10 and is negative for the markers of cutaneous squamous cell carcinoma, melanoma, angiosarcoma and leiomyosarcoma. Frequently only CD10 is positive.

Atypical fibroxanthoma (AFX) is a nodular dermal ulcerative lesion with a favorable prognosis.

AFX is characterized by its association with ultraviolet radiation, not only from a clinical aspect, but also from a molecular aspect. Making a diagnosis of AFX is challenging, and it is important to differentiate it from squamous Atypical Fibroxanthoma tumors appear as well-defined and small nodules, which are mostly painless. They form on the head and neck area, in most cases, and may ulcerate and bleed; Complete excision by surgery is curative and the prognosis of Atypical Fibroxanthoma is usually excellent. However, occasionally the tumors are known to recur BACKGROUND Atypical fibroxanthoma (AFX) is an uncommon superficial fibrohistiocytic tumor.

Atypical ﬁbroxanthoma: differential diagnosis from other sarcomatoid skin lesions Richard A Scolyer Rajmohan Murali Stanley W McCarthy John F Thompson Abstract Atypical ﬁbroxanthoma (AFX) is an uncommon cutaneous neoplasm that usually presents as a rapidly-growing nodule in sun-exposed sites in elderly patients. Fibrohistiocytic tumors of the skin comprise a large range of lesions. One such tumor is the atypical fibroxanthoma (AFX), which is widely considered as a "pseudomalignant" tumor.

Histologic Findings. The pathologic appearance of atypical fibroxanthoma (AFX) belies the usually excellent prognosis. As shown in the image below, this nonencapsulated dermal tumor is composed of large, fibrocytic, spindle-shaped and anaplastic cells arranged in a haphazard fashion, occasionally in fascicles, and usually with an increased number of mitotic figures.
