Atypical Fibroxanthoma. 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 c ….
Atypical fibroxanthoma usually stains for CD10 and is negative for the markers of cutaneous squamous cell carcinoma, melanoma, angiosarcoma and leiomyosarcoma. Frequently only CD10 is positive. Most atypical fibroxanthomas are benign, provided that strict criteria are used for diagnosis.
Atypical fibroxanthoma prognosis. Atypical fibroxanthoma rarely recurs after complete excision Although it is accepted that atypical fibroxanthoma (AFX) is an uncommon tumor, the incidence of AFX is unknown. The results of a retrospective study of surgical logs for Mohs surgery (a common treatment for AFX) from five practices in Texas offers support for the infrequent occurrence of this tumor. AFX carries a good prognosis overall. Recurrences typically occur within the first 3 years. Based on a review of 1500 published cases, the overall recurrence rate was 7.6%. Metastasis is rare, but when it occurs, the lymph nodes are often the first site of involvement.

AFX most commonly occurs on sun-exposed skin in elderly individuals. Atypical fibroxanthoma presents as a dermally based, circumscribed lesion with overlying epidermal collarette, central ulceration, and parakeratosis (Figure 1, A and B). Mild to severe solar elastosis is regularly encountered adjacent to the tumor. Atypical fibroxanthoma (AFX) was first reported by Helwig in the early 1960s . He described 20 patients with in part ulcerated tumors measuring 1–12 cm in diameter.
This growth is usually precise.
Atypical fibroxanthoma (AFX) was first reported by Helwig in the early 1960s . He described 20 patients with in part ulcerated tumors measuring 1–12 cm in diameter. They were located on the face or scalp, but in nine cases also on the limbs.
Tumors involving the dermis and superficial fat are termed atypical fibroxanthoma and rarely metastasize. Atypical fibroxanthoma From Wikipedia, the free encyclopedia Atypical fibroxanthoma of the skin is a low-grade malignancy related to malignant fibrous histiocytoma, which it resembles histologically. 2020-10-14 · 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.

Despite being markedly pleomorphic, metastases occur in less than 1 percent of cases, with the majority preceded by tumor recurrence [ 1 , 2 , 3 ]. Atypical Fibroxanthoma (Concept Id: C0346053) An intermediate cutaneous mesenchymal neoplasm of uncertain differentiation, usually affecting the actinic-damaged skin of the elderly. The tumor presents as a single cutaneous nodule which is often ulcerated. No. 6 ATYPICAL FIBROXANTHOMA OF SKIN Fretzin and Helwig 1543 TABLE 1.

Atypical fibroxanthoma (AFX) is a nodular dermal ulcerative lesion with a favorable prognosis. AFX most commonly occurs on sun-exposed skin in elderly individuals. AFX is characterized by its association with ultraviolet radiation, not only from a clinical aspect, but also from a molecular aspect.

Due to its low rate of metastasis, it is considered a benign neoplasm [1,2]. An atypical fibroxanthoma is a rare, malignant fibrohistiocytic neoplasm, which develops most commonly on the sun-exposed skin of elderly individuals. It has invasive potential, may recur locally after excision, and very rarely metastasizes. This chapter is set out as follows: BACKGROUND: Atypical fibroxanthoma (AFX) and malignant fibrous histiocytoma (MFH) are tumours of the fibrous tissue. They share similar histopathological characteristics, but they differ significantly in their prognosis.

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 prognosis. Atypical fibroxanthoma rarely recurs after complete excision Although it is accepted that atypical fibroxanthoma (AFX) is an uncommon tumor, the incidence of AFX is unknown. The results of a retrospective study of surgical logs for Mohs surgery (a common treatment for AFX) from five practices in Texas offers support for the infrequent occurrence of this tumor.
