Scar endometriosis-a sequel of caesarean section.

Endometriosis is presence of functioning endometrial tissue outside the uterine cavity, usually in the pelvis. However, its occurrence is very rare (0.03%-0.4%) in the scars which follow obstetrical and gynaecological surgeries. We are reporting two cases of scar endometriosis which occurred after caesarean sections. Both cases presented with abdominal pain at caesarean scar sites, one of which gave a cyclical history. Clinical examination revealed painful swellings in both cases, which were misdiagnosed as stitch granulomas. Wide surgical excisions were done and histopathology examination revealed a diagnosis of scar endometriosis. We are presenting these cases because of their rarity, their uncommon sites and difficulty in diagnosing the conditions clinically.
