Hysteroscopic Treatment of Primary Endometrial Marginal Zone B-cell Lymphoma (MALToma).

Primary extranodal marginal zone B-cell lymphomas (MALToma) of the endometrium are rare tumors. We report a case of MALToma diagnosed within an endometrial polyp in a patient presenting with postmenopausal vaginal bleeding. The patient underwent a conventional hysteroscopic procedure for intrauterine polyps. There was no suspicion of malignancy during the preoperative investigations or at surgery. Conventional bipolar resection of the polyps was performed. The present case demonstrates that conservative management of endometrial MALToma may be considered as a safe alternative to hysterectomy. Further data on long-term follow up is needed to confirm the safety of this conservative approach.
