Introduction: Endometriosis is a common disease in women's medicine, whose diagnosis and treatment is one of the problems of gynecologists. This condition is estrogen-dependent and is seen at the age of fertility. The presence of endometriosis in the ovary sometimes indicates itself as cysts of endometrium, which causes a debilitating pain that requires cysts to be surgically removed.
Dermoid cyst is the most common benign tumor of the ovary, which in 10% of cases is bilateral, and sometimes it can be a candidate for surgery due to the severity and pain or acute pain associated with torsion.The presence of these two diseases in the ovaries is rare and reported to be few.
Case Introduced: The case is a 30-year-old woman and a Virgin who had undergone laparoscopic surgery in Sarem's supermarket for abdominal and pelvic infections with multiple months and with bilateral ovarian endometrioma diagnosis (based on sonography and MRI). During laparoscopy, in addition to endometrium, dermoid cyst was also present in an ovary that was removed. In the patient's imaging (ultrasound and MRI), the slightest mention was made of the presence of dermoid cyst.
Conclusion: During each surgery, the possibility of another pathology should be considered simultaneously with the pathology that caused the surgery, and each of the diseases should be treated as best as possible.
