Miíase furunculóide de localização atípica

Abstract

A 63 year old black female was admitted in a public hospital complaining of itching and secretion in the gluteus for approximately one month after a trip to a rural area. The patient reported using antibiotic ointment for furuncle treatment. At the clinical examination, two hyperemic lesions showing purulent exudate were observed, and were diagnosed as furunculoid myiasis. One Dermatobia hominis larva was removed from each lesion, by means of occlusion using petroleum jelly and tweezers. Three diseases should be differentiated when dealing with this kind of occurrence: furuncles, furunculoid myiasis (caused by D. hominis) and tissue myiasis (caused by Cochliomyia hominivorax), due to the extensive tissue destruction caused by the latter.
