Extragenital endometriomas were located close to the cesarean section scar in 13 (81.25%), on umbilical region in two and inguinal region in one patient. The mean diameter of the masses was 39.5±18.1 mm (min-max: 10-75 mm). The mean follow-up period of the patients was 43 months (range: 18-79 months).
