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.

Pathology Atypical fibroxanthomas are fibrohistiocytic skin tumors with a wide range of appearances on histological examinations and a certain histological similarity to squamous cell carcinoma. The diagnosis requires skin biopsy with careful evaluation to differentiate it from other skin tumors, BACKGROUND: Atypical fibroxanthoma is a rare mesenchymal tumor of the head and neck region. METHODS: We analyzed the files of 3 large dermatology hospitals from the years 2001 to 2013 in southeast Germany. RESULTS: We identified 53 patients (56 tumors) with a male predominance. The mean age was 78.0 years ± 8.3 years. Excerpted from my dermpath board review video (https://youtu.be/Q88yDU-Pyis) for my 5-Minute Pathology Pearls video series.

Atypical fibroxanthoma is a malignant skin tumor with histologic features similar to those of undifferentiated pleomorphic sarcoma, but lacking its more aggressive behavior. The tumor is composed of pleomorphic cells with hyperchromatic nuclei and abundant cytoplasm, commonly arranged in a spindle cell pattern.

Atypical fibroxanthoma (AFX) has been considered as the non-infiltrating precursor lesion of pleomorphic dermal sarcoma (PDS), which shows an aggressive clinical behavior, because of its extensive invasion of the deeper skin layers. Se hela listan på hindawi.com Atypical fibroxanthoma is a pleomorphic dermal-based and nodular tumor affecting sun-damaged skin of the elderly (Mirza and Weedon 2005).The tumors are of uncertain differentiation and pursue an indolent clinical course if strict diagnostic criteria are applied.
