Gliomatosis peritonei (GP) indicates the peritoneal implantation of mature neuroglial tissue and is usually accompanied by ovarian mature or immature teratoma. Here, we report a case of ovarian immature teratoma associated with gliomatosis involving the peritoneum, lymph nodes and Douglas' pouch, where gliomatosis coexisted with endometriosis. As far as we know, only seven cases of GP have been reported as coexisting with endometriosis. Eight cases with mature glial tissue in the lymph nodes, i.e., nodal gliomatosis, have been published either in association with GP or in its absence. Metaplasia of pluripotent coelomic stem cells has been suggested to be responsible for the pathogenesis of endometriosis and GP rather than implantation metastases of ovarian teratomatous tumor with varying maturation. This theory is also applied to GP independently of ovarian teratomatous tumors. To the best of our knowledge, nodal gliomatosis coexisting with GP and also involving endometriosis has not yet been reported.
