Primary malignant lymphoma of the uterine corpus diagnosed by endometrial cytology. A case report.
BACKGROUND
A relatively small number of cases of primary malignant lymphoma of the uterine corpus have been reported, and it is rare for cases to be preoperatively diagnosed by cytology.


METHODS
A 59-year-old female experienced abnormal uterine bleeding of two months' duration. Preoperative evaluation of endometrial cytology revealed malignant cells. These cells demonstrated a rather round or oval configuration, with a markedly increased nuclear/cytoplasmic ratio, and were isolated and scattered in an inflammatory background. The nuclei were round or oval, and macronucleoli were marked. The cytologic diagnosis was malignant lymphoma. Postoperative histologic evaluation verified the presence of a primary malignant lymphoma in the uterine corpus, with a B-cell phenotype.


CONCLUSIONS
Preoperative endometrial cytology correctly demonstrated malignant lymphoma of the uterine corpus.
