Malignant Lymphoma Involving Ovarian Brenner Tumor

Abstract

Incidental finding in a 69-year-old woman of a diffuse large B-cell lymphoma involving the ovary with a benign Brenner tumor is presented. The benign Brenner tumor, which was composed of epithelial nests and fibrous stroma, was infiltrated by large cells with cleaved and noncleaved pleomorphic nuclei, showing B-cell phenotype. The patient was postoperatively found to have enlarged intraabdominal lymph nodes. To the best of our knowledge, this is the first reported case of Brenner tumor associated with malignant lymphoma.
