Myiasis is an infestation by dipterous larva that thrives on host's living or necrotic tissue and cause massive tissue infection. We present a case of myiasis in a 65-year-old multiparous lady with procidentia. Her examination revealed a big excavatory ulcer on dependent part and cervix indwelled with maggots. About 40 to 50 such maggots were subsequently manually removed with a forceps. After conservative management, definitive surgical treatment for prolapsed uterus was done after healing of the ulcer, within three months. It is a very rare case as only a few reports have been previously published in literature.
