We report a rare case of myiasis caused simultaneously by three dipterous species. A 54 yr-old indigent patient was admitted to Andaraí Hospital with painful eruptions on the scalp. The parieto-occipital sulcus showed two lesions caused by scratching associated with deep, odoriferous and exudative pediculosis. Larvae removed with the help of forceps and vaseline produced 153 adults, identified in the laboratory as 114 specimens of Chrysomya megacephala (F., 1794), 38 of Sarcophaga (Liopygia) ruficornis (F., 1794), and one of Musca domestica (L., 1758).
