We performed clinicopathological analyses of peritoneal dissemination caused by ovarian teratoma (PD caused by OV-T), on the English great table of 156 cases in 105 papers published in this century.
We classified PD caused by OV-T into 3 categories as follows;
1. (TP) teratomatosis peritonei (new term): PD composed by three germ teratomas cells.
2. (GP) gliomatosis peritonei: PD composed by only glia cells.
3. (MIX) mixed type: PD composed by glia and teratoma cells.
TP and MIX were newly designated in this present paper. The number of TP, GP and MIX were 22, 95 and 25, respectively. The review of these 156 cases and 105 papers were demonstrated that the clinical features between GP and TP were clearly different. TP had a more tendency of recurrent character in comparison to GP and MIX, but had a good long survivals resulted by repeated surgical resections.
