(B) Subcutaneous cellular aggregation of spindle-shaped, fibroblast-like and histiocytic cells poorly demarcated from the surrounding tissues (H&E, 100×) (C) The spindled cells are arranged in interlacing fascicles forming a storiform pattern (H&E, 200×). (D) They are accompanied by varying numbers of inflammatory cells, foam cells and siderophages as well as proliferating capillaries (H&E, 200×)
