Abstract
A 40-year-old man with old neglected, non-union, pelvic ring injury right side was surgically treated with open reduction and internal fixation. In the immediate postoperative day, the patient had a large blister adjacent to the surgical site at the right inguinal region which complicated with eschar formation, and later split skin grafting was done. Accidental burns in operation theatre are very unusual. Burns due to electro-cautery and use of alcohol-based antiseptics are well documented in the literature. Iatrogenic burns due to prolonged operating light exposure are very rare and can cause severe damage in sensitive areas like the inguinal region.
