Some years back, an email began circulating about an anthropologist named Susan McKinley who came down with a rash after returning from South America. After seeing many doctors and receiving treatments that did not alleviate the pain in her breast, she was finally sent to a dermatologist with her breast bandaged up. The dermatologist, as well as Ms. McKinley was horrified to find larvae growing underneath her bandages. While this story is absolutely false, it is partially based on true accounts. The story stemmed from a medical article about a Nigerian woman who suffered from Furuncular Myiasis of the breast where the larvae of the Tumbu fly had buried itself.
