Endometriosis means presence of functioning endometrial tissue outside the uterine cavity. It can sometimes occur in previous surgical scar. Scar endometriosis is a rare entity and should be suspected if cyclical increasing swelling, nodularity, or pain is present following obstetrical and gynaecological surgeries in past. We are reporting a rare case of scar endometriosis, which led to sudden scar dehiscence with bleeding after seven months of caesarean section and remained unhealed despite repeated attempts of wide excision followed by resuturing along with medical treatment. Finally pituitary downregulation was done with GnRH analogue and wound was allowed to heal by secondary intention.

Keywords: Endometriosis; Scar Endometrioma; Wound Dehiscence; Non Healing Wound.
