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. AFX generally occurs on the actinic-damaged skin of the elderly, especially on the face and scalp. Atypical fibroxanthoma rarely recur after complete excision with clear margins, making it virtually 100 percent cure rate. The key to not developing additional growths is to limit sun exposure to the areas of the head and back of the neck.

Helwig EB (1963) Atypical fibroxanthoma. Atypical Fibroxanthoma is a rare cutaneous tumour first described in 1963 by Elson Helwig. It has been related to ultraviolet-induced damage and most frequently occurs in sun damaged head and neck skin. Other risk factors include trauma, burns, irradiation, xeroderma pigmentosum, and organ transplantation. 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. For a long time AFX was regarded as a superficial variant of malignant fibrous histiocytoma (MFH).

Abstract. Atypical fibroxanthoma (AFX) is a rare skin neoplasm of low-grade malignancy and fibroblastic origin. AFX is a curable cutaneous disease and the diagnosis depends on knowledge of its clinical and histological features and combined immunohistochemistry markers. 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.

Mohs surgery with ≥2 cm safety margins is the treatment of choice. Histologically similar to atypical fibroxanthoma but larger and shows substantial involvement of the subcutis or beyond, perineural invasion, lymphovascular invasion or necrosis Behaves in a more aggressive manner than atypical fibroxanthoma Melanoma: Usually associated with an in situ component in the overlying epidermis The lesion has a narrow zone of transition with mildly sclerotic margins , typical of a fibroxanthoma. Lateral radiograph in the same 9-year-old boy shows an eccentric, bubbly, lucent lesion posteriorly in the distal femur with lobulated sclerotic margin but no overlying bony destruction or periosteal reaction, typical of an NOF. Atypical fibroxanthoma of the skin is a low-grade malignancy related to malignant fibrous histiocytoma, Surgical excision with clear margins.

A Atypical fibroxanthoma rarely recurs after complete excision with clear margins. Recurrence and metastasis are more likely in people that are immunosuppressed. Fortunately, atypical fibroxanthoma rarely metastasizes and recurs in only 6% to 10% of cases 6) . Atypisch fibroxanthoom (atypical fibroxanthoma, pseudosarcoma, pseudosarcomateus dermatofibroom) is een snelgroeiende, roze-rode bolronde tumor die vooral ontstaat in het gelaat van oudere mannen die veel zonneschade hebben opgelopen.
