Abstract
Gliomatosis involving lymph nodes (nodal gliomatosis) is rarely encountered in association with an ovarian teratoma, with 12 cases previously reported. We report this rare occurrence in a 23-yr-old female with an ovarian immature teratoma. The ovary contained a grade 3 immature teratoma, with immature neuroepithelium. A subcapsular liver mass contained metastatic immature teratoma with neuroepithelium. The omentum and peritoneum contained mature glial tissue, consistent with gliomatosis peritonei with no evidence of immature elements. One pelvic lymph node contained multiple nodules of mature glial tissue, diffusely positive for glial fibrillary acidic protein, in keeping with nodal gliomatosis. In reporting this case, we review prior reports of nodal gliomatosis.
