Scar endometriosis.

Endometriosis is the presence of functioning endometrium outside the uterus. Endometriosis rarely occurs in the abdominal wall. Majority of abdominal wall endometriosis occur in or adjacent to surgical scars, following caesarean section or hysterectomy. Laparotomy scar endometriosis following salpingectomy for ectopic pregnancy has rarely been reported. We report a case of scar endometriosis following laparotomy for chronic ectopic, and diagnosed by fine needle aspiration cytology (FNAC). Excision biopsy confirmed the FNAC diagnosis of scar endometriosis.
