ATYPICAL FIBROXANTHOMA OF THE SKIN A Clinicopathologic Study of 140 Cases DAVID F. FRETZIN, MD," AND ELSON B. HELWIC, MD+ In an attempt to further understand the nature of atypical fibroxanthoma of the skin, 140 lesions were subjected to clinical, histologic, and histochemical studies. Atypical fibroxanthoma (AFX) is a rare, rapidly growing, mesenchymal neoplasm that comprises 0.2% of skin tumors.1,2 AFX was first described in 1963 by Helwig et al. as a low-grade dermal tumor consisting of atypical spindle cells with an uncertain etiology.3 Since then, research has supported that Atypical fibroxanthoma (AFX) is a rare neoplastic skin disease, responsible for ∼0.2% of malignant skin cancers. AFX was first reported by Helwig in the early 1960s and is characterized as a neoplasm of low-grade malignancy of fibroblastic origin.

Atypical fibroxanthoma (AFX) is a rare neoplastic disease of the skin. Since the term was coined in the early 1960s, the disease has been viewed in many ways.

Atypical Fibroxanthoma may be diagnosed late for these reasons: Older guys may not be looking after themselves by, for example, getting a regular skin check and keeping an eye on their skin. The appearance of AFX probabaly won’t shout out ‘skin cancer’ because the appearance is non specific.
