The progress of GP is seen as relatively slow. Rare aggressive GP cases with poor prognosis were reported and no guidelines to follow for treatment.Case Presentation: Herein, we report a 17-year-old girl with a 3-year-history of GP arising from ovarian mature teratoma. Surgeries and drug therapy were used to treat the aggressively growing tumour. Genetic profiling revealed the pathogenic mutation with potential therapeutic approaches. We firstly reported the NF1 mutations in GP secondary to teratomas and may cause bad prognosis.Conclusion: GP arising from ovarian mature teratoma is rare; we found NF1 mutation could be the trigger of GP. The study may provide new insights into a better understanding of this rare disease.Keywords: ovarian mature teratoma, gliomatosis peritonei, genetic profile, NF1 mutation, MGMT promoter methylation, Trametinib
