Radiologic Atypical Fibroxanthoma Definition Cellular cutaneous mesenchymal neoplasm with at least focal pleomorphism and lacking evidence of epithelial or melanocytic differentiation Atypical fibroxanthoma (AFX) is a dermal spindle-cell tumour that typically occurs on the head and neck of sun damaged older people. The tumour-like growth should be considered a type of skin cancer but it may behave in a benign fashion. A rare type of atypical fibroxanthoma occurs in younger patients on parts of the body that are not normally overexposed to the sun. Atypical fibroxanthoma is a malignant skin tumor with histologic features similar to those of undifferentiated pleomorphic sarcoma, but lacking its more aggressive behavior.

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.

Due to its low rate of metastasis, it is considered a benign neoplasm [1,2].

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.
