Lymphangioma of the ovary after radiation due to Wilms' tumor in the childhood.

Objective: To report a case of lymphangioma of the ovary after radiation due to Wilms' tumor in the childhood.
Patient: A 19-year-old nulliparous female.
Interventions: The vaginal ultrasound showed the left ovary enlarged to 4.4 cm x 2.9 cm x 4.5 cm in size including a 3.5 cm x 2.6 cm x 3.2 cm measuring cystic solid tumor without hypervascularity. For exclusion of a malignant tumor, a laparoscopy for excision of the tumor and deep incision of the left ovary with a bipolar needle was performed to exclude deeper tumor of stromal origin. The histological examination of the tissue showed a lymphangioma beside normal ovarian tissue.
Conclusion: To our knowledge, this is the first report of lymphangioma of the ovary after radiation due to Wilms' tumor in the childhood. The impact of this finding on the patient's fertility remains unclear. As in other organs exposed to radiation, lymphangioma can also occur in the ovary. Careful follow up should be considered to this patients, because malignant transformation can not be excluded.
