The management of the retiform variant of @entity10693 remains a challenge for the gynecologist. Surgery is the preferred treatment, but it is still inconclusive whether complete staging or postoperative adjuvant therapy is necessary. A 9-year-old @entity1 was admitted with a well-circumscribed, solid @entity3928 in the lower abdomen, of size corresponding to a 20-week gravid uterus, without any androgenic manifestations. Per-operatively, the mass arose from left ovary, which had a smooth outer surface with intact capsule. A cut section was almost multiloculated with cysts ranging from 0.5 to 2.5 cm in diameter and filled with thin yellow or brown serous fluid. Left salpingo-oophorectomy, bilateral lymph node dissection, infracolic omentectomy and appendectomy were performed. The pathological diagnosis was retiform pattern of intermediate to poorly differentiated @entity10693 . The clinical stage was IA. The @entity1 was followed up 3-monthly, and was disease-free at 18-month follow-up after the initial treatment. After review of the literature, we conclude that the retiform variant is a special subtype of @entity10693 . Because of their young age, the uncertain malignant potential and rare bilaterality, @entity1 should be treated conservatively whenever possible. There is at present no good evidence that postoperative adjuvant therapy is effective in preventing recurrence.
