Introduction: Cystic lymphangioma of the ovary is a rare benign vascular tumor. Its histogenesis is still hypothetical and its preoperative diagnosis difficult to establish. We report a case of cystic lymphangioma of the ovary that was a problem with differential malignant ovarian tumor diagnosis, with a recent review of the literature.
Observation: Patient 35 years primigravida primipara without significant pelvic pain consults history dating back more than three months without increased abdominal volume or urinary or digestive signs associated. A pelvic ultrasound done complemented by magnetic resonance imaging have objectified aspect for a right ovarian cyst formation by 8 cm to confront the histological data. The patient underwent a right oophorectomy returned for mature cystic teratoma of a cystic hygroma associated. The postoperative course was uneventful and no recurrence was noted.
Results: Cystic lymphangioma of the ovary is rare benign tumor formation. There are no specific symptoms. Radiology despite progress remains inconclusive in the diagnosis of this tumor type. Histological study is the only way to confirm the diagnosis. The outcome was favorable, no cases of malignant transformation have been reported.
Conclusion: Cystic lymphangioma of the ovary is a rare benign tumor of the malformation. The diagnosis rarely made preoperatively should be considered in any cystic ovarian mass. Only complete surgical resection of the tumor is associated with prolonged survival and a favorable prognosis.
