Tunical Gliomatosis: An Uncommon Histological Entity

Background Gliomatosis peritonei (GP) is characterized by widespread implants of mature glial tissue in the peritoneum. It is most often associated with immature or mature ovarian teratomas. Case Report: A 6-month old infant developed isolated gliomatosis involving the tunica vaginalis following excision of an immature sacrococcygeal teratoma in the neonatal period. Conclusion: Tunica vaginalis gliomatosis can occur in the setting of a retroperitoneal extragonadal congenital immature teratoma.
