Synovial Sarcoma of the Hand

Figure 2

Histologic evaluation of a hand tumor indicative of monophasic synovial sarcoma. (a) At low power magnification, a well-circumscribed hypercellular mass with areas of fibrosis and high vascularity can be seen. (b) The monophasic synovial sarcoma shows a densely packed, interlacing spindled cell proliferation with monomorphic cells arranged in a myxoid stroma. The nuclei are ovoid and pale-staining with small nucleoli. Rich vascularity is present. (c) High-magnification revealing mitotic figures.
