|
We report a case of angiomatoid fibrous histiocytoma located in deep subcutaneous tissue of the left shoulder in an 11-year-old boy. An ovoid firm mass slowly increased in size for 5 months without pain or tenderness. The tumor was grossly multicystic with dense fibrous capsule and measured 7.5×7.5×4.0 cm. The locules contained hemorrhagic fluid and the inner surface was purplish brown and trabecular. The septal solid areas were cellular, consisting of histiocytoid spindle cells arranged in storiform or fascicular pattern. The tumor cells showed immuno-positivity for CD99, CD68, and desmin, and these findings were compatible with angiomatoid fibrous histiocytoma of the uncommon location.
