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.

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.

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. AFX, despite its tendency to recur after incomplete excision, has 2017-11-03 · Atypical fibroxanthoma and pleomorphic dermal sarcoma are rare mesenchymal tumors typically arising in sun-damaged skin of elderly patients. The pathogenesis of these tumors is not well understood. This video discusses the basic workup of a pleomorphic malignant cutaneous spindle cell tumor.

They appear similar to other nonmelanoma skin cancers, as nonhealing or tender pink-red skin papules or nodules. 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: Atypical fibrous histiocytoma and atypical fibroxanthoma: presentation of two cases. Kram A, Stańczyk J, Woyke S Pol J Pathol 2003;54(4):267-71.

Diagnosis is made by immunohistochemistry. AFX generally has a good prognosis.

AFX is one of the more recognizable skin cancers that can affect the body. It is characterized by the sudden development of a red or pink bump, nodule, or dome shaped ulcer. It is typically found on the head and neck of elderly patients with skin damage from over exposure to UV rays.

Introduction: Atypical fibroxanthoma (AFX) is a rare cutaneous tumor without a completely defined histogenesis which frequently develops on head and neck of elderly people. Its diagnosis is histological, of exclusion with other tumors with identical morphology. Despite its classical benign behavior some rare cases reporting distant metastasis classified it on intermediate malignancy.

Atypical fibroxanthoma (AFX) was first described by Helwig as a low-grade sarcoma with a favorable prognosis . However, since inception, it has been the source of controversy. 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 usually stains for CD10 and is negative for the markers of cutaneous squamous cell carcinoma, melanoma, angiosarcoma and leiomyosarcoma.
