Abstract
Primary lymphoma concurrent with teratoma of the ovary is exceedingly rare. Based on our review of the literature, there are only 8 case reports describing concurrent primary diffuse large B-cell lymphoma and teratoma. Here, we report the first case of primary follicular lymphoma concurrent with mature ovarian cystic teratoma, which, to our knowledge, has not been described in the literature.
Highlights
Mature cystic teratomas are the commonest ovarian tumor, accounting for 20% of all ovarian neoplasms and up to 60% of benign ovarian tumors during the reproductive years [1]
Periand postmenopausal women with Mature cystic teratoma (MCT) have a higher risk of malignant transformation at approximately 1–2% with squamous cell carcinoma being the most common type of malignancy accounting for 80-90% of cases [5]
Primary lymphoma as a neoplastic component of ovarian teratoma is exceptionally rare with only 8 reported cases in the literature (Table 1); the lymphoma type reported in all cases is diffuse large B-cell lymphoma
Summary
Mature cystic teratomas are the commonest ovarian tumor, accounting for 20% of all ovarian neoplasms and up to 60% of benign ovarian tumors during the reproductive years [1]. Most ovarian lymphomas represent secondary involvement by a systemic disease [3]. Primary ovarian lymphomas are rare and account for less than 1% of all cases of non-Hodgkin’s lymphomas (NHLs) [4]. Concurrent involvement by NHL and MCT is exceedingly rare with only eight reported cases in the literature (Table 1). We report the occurrence of primary Stage IE, Grade 3A ovarian follicular lymphoma within a MCT in a 62-year-old woman who underwent a laparoscopic bilateral salpingo-oophorectomy and omentectomy. Thorough radiologic investigations and staging bone marrow studies excluded a systemic disease. To our knowledge, this is the first case report of primary follicular lymphoma concurrent with MCT. The exclusive presence of follicular lymphoma within the MCT suggests it may have arisen from it
