Lymphangiomas of the ovary are rare tumors, with only 13 cases reported. The diagnoses of these tumors have been based on histologic findings without immunohistochemical confirmation of endothelial cell origin. It is uncertain if these tumors are true neoplasms or if some represent reactive lesions. In this report, the literature is reviewed, and a 53-year-old woman with bilateral ovarian lymphangiomas is described. The ovarian masses were composed of numerous, thin-walled, cystic spaces containing a proteinaceous fluid, mature lymphocytes, and occasional erythrocytes. The cyst walls were lined by flat, benign-appearing cells that were immunoreactive for factor VIII-related antigen, CD34, and CD31. Further examination of the specimen showed absent fallopian tube fimbriae, tuboovarian adhesions, and chronic follicular salpingitis, suggesting that the lymphatic proliferation in the ovaries was a reactive change secondary to impaired regional lymphatic drainage.
