title: Two cases of uterine malignant lymphoma diagnosed by needle biopsy.
abstract: The incidence of primary malignant lymphoma arising in the female genital tract is extremely rare and constitutes approximately 0.05% of malignant tumors. Uterine malignant lymphoma develops in the endometrial stroma, causing minimal necrosis. It is therefore difficult to diagnose malignant lymphoma, as it does not involve genital bleeding or epithelial defects. We have performed transcervical needle biopsies from deep in the myometrium, with the purpose of diagnosing uterine muscle layer lesions, such as leiomyosarcoma, but this is an unusual method. In this report, we suggest that transcervical needle biopsy is useful in the diagnosis of uterine malignant lymphoma.
