What is angiomatoid fibrous histiocytoma?

Angiomatoid fibrous histiocytoma (AFH) is a rare type of soft tissue tumor. It commonly affects your extremities, such as your arms, legs, hands or feet.

A histiocytoma is a tumor that contains normal immune cells (histiocytes) that have traveled from one area of your body to another. The term “angiomatoid” describes the vascular-like appearance of the tumor. “Fibrous” refers to the ropey, sinewy nature of the mass.
