RESUMO
Lymphangioma is a rare proliferation of the lymphatic system which is classified as either lymphangioma circumscription or carvenous lymphangioma. The involvement of the vulva is very rare and only a small number of case reports have been made on carvenous lymphangioma of the vulva. We herein report a case of 20-year-old unmarried girl presented with gradually expanding and painless tumor of the left labium majus. The mass was removed surgically and pathology confirmed as carvenous lymphangioma, with no recurrences to date.
RESUMO
Although a gastrointestinal-type epithelium is observed in 7-13% of mature cystic teratoma cases, the occurrence of a grossly visible, organized gastrointestinal loop formation is very rare. Presented here is the case of a 14-year-old girl with malignant mixed germ cell tumor in the ovaries. In her left ovary a grossly visible, intestinal loop, 9 cm long, with hanging mesentery attached to the cystic wall of a mature cystic teratoma associated with a yolk sac tumor was observed, and in her right ovary another mature cystic teratoma was observed. Microscopy of the intestinal loop indicated a well-organized, intact layer of small intestinal wall. The yolk sac tumor predominantly had a poly-vitelline pattern. Previously, gastrointestinal wall or epithelium that was identified on microscopy has been reported. To the authors' knowledge this is the first case report of the formation of a grossly visible, completely developed intestinal loop in a malignant mixed germ cell tumor.
