Abstract: Gliomatosis peritonei（GP） is a rare disease. Up to now, only more than 100 cases have been reported. The typical clinical manifestations are benign and mature glial tissue widely distributed in the peritoneum, often coexisting with ovarian immature teratoma. Clinically, it is necessary to undergo a thorough biopsy to identify the mature glial tissue before the diagnosis can be confirmed. Treatment is mostly associated with primary tumors，but because of the rarity of the disease, a standard treatment scheme has not yet been established. In addition, because of the possibility of malignant transformation in a few cases, long-term follow-up is needed. In recent years, new progress has been made in the pathogenesis, treatment and follow-up of GP. Therefore, the research progress of GP is discussed in this paper to provide reference for subsequent treatment.
