Implantes peritoneales de tejido glial maduro (gliomatosis peritoneal) y de otros tejidos maduros asociados a teratoma ovárico inmaduro

Peritoneal gliomatosis is a very rare metastatic form of ovarian teratoma, characterized by miliary dissemination of glial tissue inside the peritoneal cavity in patients with an ovarian - usually immature - teratoma. Peritoneal gliomatosis may resemble peritoneal carcinomatosis. Despite peritoneal dissemination, if the glial tissue implants are composed of mature tissue, peritoneal gliomatosis does not adversely affect the prognosis of the primary ovarian teratoma. Consequently, conservative treatment is warranted. The main prognostic factor is the histological grade of the teratoma, which indicates the required complementary treatment. The prognosis of peritoneal gliomatosis is favorable, although cases of malignant transformation have been reported.
