Metastatic carcinoma : Abstract. Atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) tumors share many clinical, etiologic, and histologic features and likely represent components of a tumor spectrum. In dermatologic oncology, differentiating between AFX and PDS is pivotal as tumors with histological features consistent with PDS are more likely to behave in a clinically aggressive manner. Atypical fibroxanthoma (AFX) is a tumor that occurs primarily in older individuals after the skin of the head and neck has been damaged significantly by sun exposure and/or therapeutic radiation. The body of literature supporting the use of Mohs micrographic surgery (MMS) in tumors outside the main indications (basal cell carcinoma, squamous cell carcinoma, dermatofibrosacroma protuberans, lentigo maligna) is constantly growing, but it is still based on case reports, case series, or at best institutional case series that focus on a single malignancy.

What is the outcome for atypical fibroxanthoma? Background: Atypical fibroxanthoma (AFX) is a fibrohistiocytic tumor with relatively high local recurrence rates but low metastatic potential. Wide local excision (WLE) and Mohs micrographic surgery (MMS) are common treatments, although no consensus exists regarding optimal therapy.
