greater tendency to exhibit on the left side, and it most frequently affects women in the fifth decade of life and they are usually asymptomatic.
Objectives: To report the case of a patient with benign Brenner's tumor, histopathologically confirmed and to carry out a review of the literature regarding the clinical and histopathological diagnosis of this entity in contrast with other entities.
Case report: 54-year-old patient, with a personal pathological history, attended the Gynecology consultation on January 22, 2019 for presenting discomfort under her belly of several months of evolution. Laparotomy was performed due to suspicion of an ovarian cyst showing a rounded mass 12 cm in diameter, irregular surface, and whitish with translucent areas. Left oophorectomy was performed.
