Histological photomicrographs. Hematoxylin and eosin stain (×50) shows an epithelioid neoplasm composed of hyper-cellular, moderately pleomorphic round to polygonal tumor cells embedded in a myxoid stroma. There are areas of hemorrhage or necrosis (A). Hematoxylin and eosin stain (× 400) Higher power magnification demonstrates the cells have round to ovoid nuclei, prominent nucleoli, and abundant eosinophilic cytoplasm. Mitotic figures are present (B).
