Atypical fibroxanthoma is a malignant skin tumor with histologic features similar to those of undifferentiated

In summary, our data demonstrate that atypical fibroxanthoma and pleomorphic dermal sarcoma harbor a large number of genetic alterations, including frequent

Adequately treated, AFX has an excellent prognosis, but long-term follow-up is recommended due to the potential for aggressive behavior. Atypical Fibroxanthoma - Histological Diagnosis, Immunohistochemical Markers and Concepts of Therapy The tumor presents as a single cutaneous nodule which is often ulcerated. 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.

This chapter is set out as follows: 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. 2017-12-08 2010-09-01 Atypical fibroxanthoma (AFX): Four cases Deba P Sarma, MD., Omaha 1.

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. Definition. A morphologic variant of atypical fibroxanthoma characterized by the presence of spindle-shaped fibrohistiocytic cells and a storiform growth pattern. [from NCI] 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.

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 (AFX) typically presents with the sudden onset of an asymptomatic, solitary, growth of the head and neck.

Despite its highly atypical histological appearance it is almost always associated with innocuous clinical behaviour.

Frequently only CD10 is positive. 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.

We identified 87 patients (mean age of 80.0 ± 8.4 years) with 105 confirmed tumors. Of these patients 86.2% were males. Treatment and prognosis Atypical fibroxanthomas are surgically removed and have a good prognosis. They might locally reoccur with the necessity of re-surgery.
