case_images: On the opening of the ileal lumen, a 2 x 1,5 x 1 cm, secondarily ulcerated, solid, nodular, gray white tumor mass was seen close to the resection margin (Figure 1).
case_images: (a) Perivascular tumor cells with clear to slightly eosinophilic granular cytoplasm and round vesicular nuclei, (b) submucosal tumor mass.

case_images: Histological evaluation demonstrated a tumoral tissue composing nests of round-polygonal epithelioid cells with abundant clear to slightly eosinophilic granular cytoplasm and round vesicular nuclei, located at the periphery of the thin vascular network (Figure 2(a)).  Tumor was secondarily ulcerated and invading submucosa (Figure 2(b)), muscularis propria, and serosa.

case_images: SMA (Figure 3), HMB45 (Figure 4), Melan-A (Figure 5), CD99, and E cadherin and negative for S100, desmin, CD117, CD34, CD31, AE1/3, EMA, CD10, RCC, CD45, chromogranin A, synaptophysin, ER, PR, cerbB2, cyclin D1, CK20, CK5-6, CK19, bcl2, GCDFP15, MFG, and TTF1 immunohistochemically. So the diagnosis was ileal PEComa.
