Abstract
A first human case in Japan was reported in which the maggots of human botfly (Dermatobia hominis) were found in the subcutaneous tissue of a 70-year-old man living in Tsukui-cho, Kanagawa prefecture. Although this myiasis is a disease of American tropics and this patient had been infected by these larvae in Brazil, the modern air travel can bring this tropical disease to Japan. This instance suggests that the tropical and subtropical diseases can be introduced into the extralimital regions in this country when the patient returned from abroad without an appropriate treatment. The liquid paraffin or fresh pork fat are used to cut off an air supply to the maggot in red cutaneous nodule. The larva escapes from a boil by this treatment.
