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.

The tumor presents as a single cutaneous nodule which is often ulcerated. 2017-12-08 2010-09-01 Atypical fibroxanthoma (AFX): Four cases Deba P Sarma, MD., Omaha 1.

Rarely AFX has been described in young and in areas without evidence of actinic damage. Atypical fibroxanthomas are uncommon but usually occur on the head and neck of older people. They may look like other skin cancers (other than melanoma) and often appear as pink-red raised areas or bumps that do not heal and may be tender.

Metastasis is a rare event. The clinical features, diagnosis, and management of AFX are discussed here. Undifferentiated pleomorphic sarcoma is reviewed separately. Atypical fibroxanthoma is a type of skin cancer which is often misdiagnosed as a less serious skin condition. Normally, cells in the body will grow and divide to replace old or damaged cells. This growth is usually precise.

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 ….

No. What are the symptoms of Atypical Fibroxanthoma? A weeping, or sometimes bleeding growth, or multiple lumps, may grow over a few months on the head or neck area. The lumps may be pink or red in colour.

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 ].

AFX is characterized by its assoc 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. Making a diagnosis of AFX is challenging, and it is important to differentiate it from squamous Atypical Fibroxanthoma tumors appear as well-defined and small nodules, which are mostly painless.
