Carcinomesenchymoma of the uterus

A unique case of intramural uterine tumor composed of malignant epithelium and benign smooth muscle, adipose tissue, and cartilage is reported. This tumor, which the authors designated "carcinomesenchymoma," apparently represents an example of a previously unreported variant of mixed müllerian tumor that is composed of malignant epithelium and benign mesenchymal elements.
