Primary malignant lymphoma of the uterus.

The clinical and pathological findings in a 59-year-old woman with a primary malignant lymphoma of the corpus uteri are described. There was a period of eight months between detection of the uterine lesion and evidence of disease elsewhere in the body. The patient died of disseminated lymphoma, and the distribution of secondary deposits were suggestive of spread via the right ovarian-uterine venous system.The criteria for acceptance of a diagnosis of primary uterine lymphoma are discussed and the previous literature is reviewed. There have been nine acceptable cases of primary uterine lymphoma recorded: four in the corpus uteri and five in the cervix. The differential diagnosis from stromal sarcoma, anaplastic endometrial adenocarcinoma, leiomyosarcoma, and benign lymphoid hyperplasia is discussed.
