Fig. 1: Histomorphology of the uterine and vaginal tumors.

From: Recurrent MEIS1-NCOA2/1 fusions in a subset of low-grade spindle cell sarcomas frequently involving the genitourinary and gynecologic tracts

Fig. 1

The uterine tumor (case 1, A–C) shows short spindle to ovoid cells with alternating cellularity (A), vague short fascicles, cellular aggregates of primitive cells (B), and myxoid to hyalinized stroma in the hypocellular area (C). The vaginal tumor (case 2, D–F) shows monomorphic spindle cells with alternating cellularity and rich vasculature (D), in whorling (D) to storiform (E) patterns. NCOA2 immunostaining shows diffuse moderate staining (F).
