Non-Hodgkin lymphoma of the puerperal uterus.

Non-Hodgkin lymphoma was diagnosed initially in a curettage specimen of a puerperal uterus 3 weeks after normal delivery of a healthy infant. The disease, which probably existed during the last trimester of pregnancy, was classified as clinical stage IVb. Combination chemotherapy resulted in immediate improvement and complete remission after several months. Histopathologic examination of the uterus 10 months after starting therapy demonstrated complete disappearance of the malignant lymphoma.
