Abstract

Rare adverse effects of India ink injection spillage during colonoscopy have been reported. We present a case report in which prior colonoscopic India ink tattooing was found to mimic intraperitoneal endometriosis in a 48 year-old woman undergoing laparoscopic sterilization. Multiple black lesions suspicious for endometriosis involving the anterior and posterior cul-de-sac, left ovary, and omentum were found. A pathological assessment showed peritoneal tissue with focal dark pigment associated with mild chronic inflammation and deposition of tattoo pigment; there was no evidence of endometriosis in the specimens. Surgical recognition of tattoo ink spillage in the peritoneum is very important to prevent misinterpretation of peritoneal findings.

Keywords: Colonoscopic tattooing; Endometriosis; Laparoscopy.
