A patient with surgical scar endometriosis, a rare condition, was presented. The patient was 30 years old, gave birth twice by cesarean section, her last delivery was seven years ago. She appealed to the outpatients' clinic because of the complaints of pain, swelling and redness on the scar site, her complaints began one year after the last delivery and continued. The complaints did not alter by menstrual cycle. On the examination, there was a painful hyperemic lesion 2x2crn in size which was raised from the skin, located at the right of the scar, assumed to be associated with the fixed fascia and another lesion 2x2crn in size which could not be noticed by inspection but be palpated was found. The lesions described were totally excised. The result of paraffin block examination of the material was reported as endometriosis. Pain on the scar site with menstrual period, enlargement and discoloration of the lesions are classical signs of scar endometriosis. But the patients do not always present these findings. Endometriosis should also be remembered along with other reasons when lesions occur on the scar site after surgery.
