Rare case of ovarian cystic lymphangioma.

Lymphangiomas are rare, generally benign tumors of the lymphatic system comprised of multiple cystic spaces lined with endothelium. Lymphangiomas may arise in any part of the body. Lymphangioma of the ovary is rare; we have identified only 13 reports in a 50-year literature survey (PubMed 1959-2009). Typically, lymphangiomas are slow-growing tumors that remain asymptomatic for a long time. They are most often found incidentally in abdominal or pelvic imaging studies or at surgery or autopsy. Wide excision of the lesion with microscopically clear margins is the best approach when feasible. A postmenopausal woman had a symptomatic pelvic mass. Imaging studies demonstrated a complex left ovarian cyst. Complete removal of a cystic lymphangioma was successfully performed at laparoscopy. Cystic lymphangiomas should be included in the differential diagnosis of an ovarian cystic mass, and laparoscopic excision may be the method of treatment.
