title: Myxoid malignant fibrous histiocytoma with erythrophagocytosis.
abstract: A tumor that formed multiple protuberant masses on the foot and leg of a 50-year-old white male had the light and electron microscopic features of a myxoid malignant fibrous histiocytoma. Ultrastructurally, the cells had some fibroblastic features. Extravasated erythrocytes were present throughout the tumor nodules and many had been phagocytosed by the tumor cells. Endothelial cell markers were negative.
