I’m sorry to hear that you’ve been recently diagnosed with Atypical Fibroxanthoma (AFx) in addition to lung cancer. Here is a short video of Mayo Clinic dermatologic surgeon, Dr. Jerry Brewer discussing AFx. He tells us about the risk factors, diagnosis and treatment of this rare form of skin cancer.

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 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). Atypical fibroxanthoma (AFX) is a dermal spindle-cell sarcoma that is considered a superficial and clinically benign presentation of pleomorphic dermal sarcoma, malignant fibrous histiocytoma, and undifferentiated pleomorphic sarcoma.

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.

has an excellent prognosis, b ut long-term follow-up is recommended due to the potential for aggr essive behavior. Atypical fibroxanthoma (AFX) is a rare primary mesenchymal skin tumor of Atypical fibroxanthoma of the skin is a low-grade malignancy related to malignant fibrous histiocytoma, which it resembles histologically.: 613 Atypical fibroxanthoma (AFX) is an uncommon cutaneous neoplasm that usually presents as a rapidly-growing nodule in sun-exposed sites in elderly patients.

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.

Thus far, there are no guidelines for diagnosis and therapy of this tumor. BACKGROUND Atypical fibroxanthoma (AFX) is an uncommon superficial fibrohistiocytic tumor. 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 an uncommon, pleomorphic, spindle cell cutaneous malignancy that most commonly presents as a solitary red or pink papule or nodule on the head or neck . Exposure to ultraviolet light most likely contributes to the development of AFX.

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. Once enough cells are produced to replace the old ones, normal cells stop dividing.

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. 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. AFX is now generally regarded as the superficial counterpart of undifferentiated pleomorphic sarcoma (so-called malignant 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.

Most atypical fibroxanthomas are benign, provided that strict criteria are used for diagnosis. 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 fibroxanthomas are uncommon but usually occur on the head and neck of older people.

Atypical fibroxanthoma rates a low-grade sarcoma, usually occurring on sun-exposed areas of the head and neck in elderly patients. The prognosis is generally excellent when treated with adequate excision of the primary tumor.

Atypical fibroxanthoma is a malignant skin tumor with histologic features similar to those of undifferentiated pleomorphic sarcoma, but lacking its more aggressive behavior.

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. Atypical fibroxanthoma of the skin is a low-grade malignancy related to malignant fibrous histiocytoma, which it resembles histologically.: 613 2017-11-03 2020-06-04 Histologic Findings. The pathologic appearance of atypical fibroxanthoma (AFX) belies the usually excellent prognosis. As shown in the image below, this nonencapsulated dermal tumor is composed of large, fibrocytic, spindle-shaped and anaplastic cells arranged in a haphazard fashion, occasionally in fascicles, and usually with an increased number of mitotic figures.
