Abstract

Primary (localized) non-Hodgkin's lymphoma (NHL) of the ovary is rare. We studied eight cases of primary ovarian NHL to better understand the clinicopathologic and immunophenotypic features of these tumors. The patients ranged in age from 29 to 62 years (mean 47 years). Pelvic complaints were the most common symptoms; however, three of eight neoplasms were discovered incidentally. All tumors were unilateral and Ann Arbor stage I(E). The three incidental NHL were microscopic (largest 1.2 cm), whereas the grossly evident lesions ranged from 7.5 to 20 cm (mean 13.3). Each tumor was classified according to the World Health Organization Classification as follows: diffuse large B-cell lymphoma (three cases), follicular lymphoma (two cases), Burkitt lymphoma (one case), T-cell anaplastic large cell lymphoma (one case), and precursor T-lymphoblastic lymphoma (one case). Six tumors were of B-cell lineage, and two tumors were of T-cell lineage. All three diffuse large B-cell lymphomas were positive for BCL-6, two were positive for CD10, and two were positive for BCL-2. Estrogen and progesterone receptors were negative in all NHLs assessed. Patients were treated by various combinations of surgery, chemotherapy, and radiotherapy. Clinical follow-up ranged from 1.3 to 11.7 years (mean 5.2) and all patients were alive without disease at last follow-up. We conclude that most patients with primary ovarian NHL present with symptoms attributable to an ovarian mass, but in a subset of patients ovarian NHL may be detected incidentally. With appropriate therapy, patients appear to have a favorable prognosis although follow-up is short for some patients in this study.
