Parasitic ovarian dermoid cysts are very rare. We report a rare case of bilateral ovarian dermoid cysts with parasitic teratoma at the hepato renal space measuring 11x11x6 cm while the other was twisted measuring 10x6x5 cm.Right ovary and tube were absent. The mass found at the hepato renal space was surrounded by and adherent to the omentum with viable tubal fimbria like structure at upper surface. Histopathologically both masses were confirmed as mature ovarian teratoma. The etiology of parasitic teratoma would be due to torsion followed by autoamputation and reimplantation of the right ovarian dermoid cyst.
寄生性卵巢皮样囊肿非常罕见。我们报告一例罕见的双侧卵巢皮样囊肿病例，其中一个位于肝肾间隙的寄生性畸胎瘤大小为11×11×6厘米，另一个发生扭转，大小为10×6×5厘米。右侧卵巢和输卵管缺如。在肝肾间隙发现的肿块被大网膜包裹并与之粘连，其上表面有类似输卵管伞端的存活结构。组织病理学检查证实两个肿块均为成熟卵巢畸胎瘤。寄生性畸胎瘤的病因可能是右侧卵巢皮样囊肿扭转后发生自截并重新植入。
