Background: Atypical fibroxanthoma (AFX) represents an uncommon skin tumor typically occurring on sun‐damaged skin of the elderly. Histopathologic variants include spindled, clear cell, osteoid, osteoclastic, chondroid, pigmented, granular cell and myxoid lesions.

We report two rare examples of dermal fibrohistiocytic stromal tumors: one case of atypical fibrous histiocytoma (AFH) and another one of atypical fibroxanthoma (AFX), which can be confused in surgical pathology diagnosis with high-grade malignant neoplasm. Histologically, a proliferation of mononuc … 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. Clinically, lesions usually are suggestive of malignancy because they arise rapidly (over just a few weeks or months) in skin in which other skin Microscopic diagnosis was that of a collision lesion involving atypical fibroxanthoma and basal cell carcinoma.

Atypical fibroxanthoma (AFX) is a dermal spindle-cell tumour that typically occurs on the head and neck of sun damaged older people. The tumour-like growth should be considered a type of skin cancer but it may behave in a benign fashion. A rare type of atypical fibroxanthoma occurs in younger patients on parts of the body that are not normally overexposed to the sun. Pathology quiz case 3.

Although these entities are not new in the dermatopathology world, the presence of a collision tumour involving these two entities is extremely rare and should be considered in diagnosing histologically challenging skin lesions. Pathology Atypical fibroxanthomas are fibrohistiocytic skin tumors with a wide range of appearances on histological examinations and a certain histological similarity to squamous cell carcinoma. The diagnosis requires skin biopsy with careful evaluation to differentiate it from other skin tumors, BACKGROUND: Atypical fibroxanthoma is a rare mesenchymal tumor of the head and neck region. METHODS: We analyzed the files of 3 large dermatology hospitals from the years 2001 to 2013 in southeast Germany. RESULTS: We identified 53 patients (56 tumors) with a male predominance.
