title: Invasive intestinal myiasis in a young male presenting as fungating rectal mass: an unusual presentation.
abstract: Intestinal myiasis is usually an accidental phenomenon which is transient and asymptomatic. It occurs due to intake of contaminated food or water containing fly larvae or eggs. We report a case of invasive intestinal myiasis presenting with complaint of pain, blood-mixed mucous discharge per rectum along with passage of maggots in stool. On proctoscopy an irregular fungating rectal growth with maggots was detected in rectum and anal canal. Excision of growth with diversion colostomy was done. On histopathology numerous variable-sized larvae in different stages of development were detected throughout the inflamed and necrosed bowel wall. No tumor was seen. With maintenance of proper hygiene, vermicide anti inflammatory and purgatives were given. Patient became alright after colostomy closure. The symptomatic presentation as a mass lesion and necessity for surgical intervention prompted us to report this rare case.
