Abstract. 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 - Etiology, pathophysiology, symptoms, signs, diagnosis & prognosis from the MSD Manuals - Medical Professional Version. Atypical fibroxanthoma (AFX) is a nodular dermal ulcerative lesion with a favorable prognosis. AFX most commonly occurs on sun-exposed skin in elderly individuals.

Atypical fibroxanthoma (AFX) is a rare, low-grade sarcoma that most often occurs on sun-exposed skin of the head and neck in individuals older than 60 years. It presents as a solitary, red or pink, firm papule or nodule that grows rapidly over the course of several months. This video discusses the basic workup of a pleomorphic malignant cutaneous spindle cell tumor. The main differential diagnosis includes spindle cell melanoma As expected, overall survival was relatively low (5-year survival: 88.7%, 10-year survival: 86.9%, 20-year survival: 85.6%), mainly due to old age and existing co- Atypical fibroxanthoma is a malignant skin tumor with histologic features similar to those of undifferentiated Atypical fibroxanthoma (AFX) typically presents with the sudden onset of an asymptomatic, solitary, growth of the head and neck.

They were located on the face or scalp, but in nine cases also on the limbs.

It is not commonly painful or sore or itchy.

It was originally described as a low‐grade dermal tumor of atypical spindle cells, but this view has changed, and it is generally considered to be a tumor of intermediate malignant potential. Atypical fibroxanthoma (AFX) is a dermal mesenchymal neoplasm arising in sun-damaged skin, primarily of the head and neck region of older men. Conservative excision cures most. However, varying degrees of subcutaneous involvement can lead to a more aggressive course and rare metastases. Atypical fibroxanthoma is a low-grade sarcoma of the skin. (See also Overview of Skin Cancer.) Atypical fibroxanthomas are rare among nonmelanoma skin cancers.

Atypical fibroxanthoma (AFX) is an uncommon cutaneous neoplasm that usually presents as a rapidly-growing nodule in sun-exposed sites in elderly patients. Despite its highly atypical histological appearance it is almost always associated with innocuous clinical behaviour. 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 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 cell pattern. Atypical fibroxanthomas might be detected as a nodular skin lesion of some millimeters up to some centimeters on ultrasound, CT or MRI. After administration of a contrast agent, it has been described to show enhancement. Treatment and prognosis. Atypical fibroxanthomas are surgically removed and have a good prognosis.

Once enough cells are produced to replace the old ones, normal cells stop dividing. 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. 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 Abstract Background: Atypical fibroxanthoma (AFX) is an uncommon, rapidly growing cutaneous neoplasm of uncertain histogenesis. Thus far, there are no guidelines for diagnosis and therapy of this tumor. Microscopically, it is characterized by the presence of highly atypical cytologic features, pleomorphism and abundant mitotic figures. The vast majority of patients have an excellent prognosis following conservative therapy.

Atypical fibroxanthoma rarely recurs after complete excision with clear margins.

Exposure to ultraviolet light most likely contributes to the development of AFX. Atypical fibroxanthoma (AFX) is an ultraviolet radiation-associated dermal neoplasm.
