Angiomatoid fibrous histiocytoma in a 25-year-old male

Subcutaneous Angiomatoid Fibrous Histiocytoma Mimicking Metastatic Melanoma

Angiomatoid fibrous histiocytoma is an uncommon soft-tissue tumor of intermediate malignancy that is often misdiagnosed initially. As there is not one immunohistochemical marker that consequently stains positive or negative for angiomatoid fibrous histiocytoma, molecular diagnostics are becoming more widely used. So far three translocations have been reported to arise in angiomatoid fibrous his...

Solid variant of angiomatoid fibrous histiocytoma masked by interstitial granuloma annulare in a 13-year-old child: no evidence for translocation breakpoints.

Aneurysmal benign fibrous histiocytoma with atrophic features.

Aneurysmal benign fibrous histiocytoma is an uncommon pathologic variant of dermatofibroma. In addition to the features of a typical dermatofibroma, it has large cleft-like or cavernous blood-filled spaces with numerous hemosiderin pigments. It should be differentiated from angiomatoid malignant fibrous histiocytoma, malignant melanoma, and vascular tumors such as Kaposi's sarcoma and angiosarc...

Aneurysmal ("angiomatoid") fibrous histiocytoma in a child.

A case of aneurysmal ("angiomatoid") fibrous histiocytoma (AFH) in a 12-year-old girl is presented with its unusual clinicopathologic features. The lesion had the full microscopic characteristics of AFH described in prior reports, but it also had some features that differed from the original description of the disorder, such as the involvement of subcutis, its occurrence in the scalp, and a doc...

Angiomatoid fibrous histiocytoma: case report and review of the literature.

Angiomatoid fibrous histiocytoma is a rare soft tissue tumor of uncertain differentiation and low metastatic potential, which occurs predominantly in children and young adults. It occurs mostly within the extremities, trunk, head and neck. It can be associated with systemic manifestations such as anemia, pyrexia and malaise. Its morphology is distinct, with an outer shell of lymphoid tissue, sh...
