According to Dr. F. Zumpt, the term "myiasis" is defined as the infestation of live man and vertebrate animals with dipterous larvae. Many different species of flies produce myiasis. Many cases of myiasis have been reported from all over the world, but not so many in Japan. External myiasis is mostly otomyiasis in Japan. External myiasis except for otomyiasis reported only 4 cases up to the present. This case appears to be the 5th report of external myiasis in Japan. The patient was a 61-year-old man, living in Nagoya-city. He was admitted with the papillary adenocarcinoma on the left parotid gland. Several dipterous larvae were found in the necrotic center of the tumor. These larvae were 5 to 6mm in body length. Thirteen larvae were collected from the patient. These larvae were reared using the meat of a racoon dog with a temperature at 25℃ and at 75% relative humidity. One male and 2 female flies emerged. After a detailed examination, they have been all identified as Boettcherisca peregrina (Robineau-Desvoidy, 1830). Findings on clinical case, the life cycle and species of the fly were discussed.
