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, Radiographic features

Fibroxanthoma pathology outlines

Atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) share clinical, pathological, immunohistochemical and molecular features, though PDS is associated with a more aggressive behavior. Methods. We reviewed 71 tumors fulfilling criteria for AFX and PDS to further stratify their biological potential. Results The combination of immunohistochemistry stains supported the suspicion of a collision lesion involving atypical fibroxanthoma (AFX) and a basal cell carcinoma (BCC). 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.

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 fibroxanthoma (AFX) or undifferentiated pleomorphic sarcoma (UPS) is a rare malignant neoplastic disease of the skin. At the beginning of the 1960s AFX was described as an independent entity and superficial variant of malignant fibrous histiocytoma (MFH). Since then, many controversies on t … pleomorphic dermal sarcoma or undifferentiated pleomorphic sarcoma of skin. This tumor group is not well documented in the literature, and its characteristics are only poorly defined. To study the clinical and pathologic spectrum more comprehensively, we retrieved 32 pleomorphic dermal sarcomas from our departmental files.

Nonossifying fibromas (NOFs) are the most common benign bone tumor in children. They do not become cancerous and they do not spread (metastasize). In most cases, no treatment is necessary because NOFs typically go away on their own when a child is fully grown.

Microscopic images of Atypical Fibroxanthoma Clinical presentation: - The tumour usually presents as solitary, rapidly growing dome shaped ulcerated and crusted nodule, usually less than 2 cm in diameter, on the head or neck region of the elderly.The lesion usually … Fibroxanthoma of bone is a confusing term that is sometimes used to encompass non-ossifying fibroma and fibrous cortical defect, and at other times synonymously with just non-ossifying fibromas.As non-ossifying fibroma and fibrous cortical defect are histologically the same, and differ only in size (non-ossifying fibroma >2-3 cm) it is safe to not lose too much sleep over this one. Atypical fibroxanthoma (AFX) is a rare spindle cell neoplasm predominantly found on the head and neck of elderly individuals with sun-damaged skin, with no evidence-based guidelines for their management.
