Subcutis: the subcutis is expanded by an ill defined, invasive, unencapsulated, multilobular, densely cellular neoplasm which contains large pools of blood. The neoplasm is composed of solid areas and interconnected and tortuous blood-filed vascular spaces supported by a scant amount of fibrovascular stroma. There is prominent lymphocytic infiltration (*) at the periphery of the tumor. A few bundles of striated skeletal muscle fibers are entrapped within the tumor. The tumor is infiltrated by a moderate number of hemosiderin-ladden macrophages. |
