RESUMO
Myiasis is the infestation of the organs or tissues of host animals or humans by the larval stages of dipterous flies. The fly larvae feed direct on the host's necrotic or living tissue. The hosts are usually mammals. Myiasis is often classified according to the anatomical position in or on the mammals that the larvae infest. It may be described as dermal, sub-dermal or cutaneous, nasopharyngeal, ocular, intestinal/enteric or urinogenital. We can distinguish three types of myiasis: accidental, facultative, and obligate. We report the case of a 58-year-old Syrian male who was hospitalized at Al Moassat University Hospital with the complaint of worm-shaped organisms on a tumor on his left external ear. The organisms were diagnosed as myiasis larvas of Lucilia [green blow; family: Calliphoridae]
