Abstract Huge ovarian mass is an uncommon finding in a female adolescent. Dermoid cysts are usually having very slow rate of growth about 1.8 mm per year, so giant dermoid cysts have been rarely reported in the literature. Here we present a case of huge cyst in a 15-year old girl having severe abdominal pain. Abdominal examination revealed regular cystic tender pelvi-abdominal mass corresponding to the size of 28 weeks pregnant uterus by palpation. Abdominal ultrasonography revealed the presence of right ovarian cyst measured 20 × 20 × 18 cm. Colour Doppler evaluation revealed no blood flow in the periphery of the mass. All investigations were normal. Immediate laparotomy revealed right gangrenous huge ovarian mass. Salpingo-oophorectomy was done and histopathological examination revealed twisted gangrenous dermoid cyst. She stayed at hospital for 3 days and then discharged in a healthy condition.
