Xanthomatous endometritis.

A further case of xanthomatous endometritis, characterized by the presence of histiocytic cells in the endometrium, in the absence of carcinoma is described. This lesion seems to be a rare complication of hematometra with cervical occlusion. The foam cells would appear to be macrophages, components of a nonspecific inflammatory reaction, which have phagocytosed breakdown elements of retained endometrial hemorrhage.
