ABSTRACT
Introduction. Myasis is the parasitism of organs and tissues of warm-blooded vertebrates by the larvae of flies of different species.Case report. Thirteen year old female. Her house is provided with running water and sewer she had contact with farm house poultry. She began presenting symptoms 5 days prior to admission she presented with nasal discharge and pharyngitis. Her temperature was 38° C. At emergency services the patient was diagnosed with bacterial pharyngytis. Penicillin and clorfeniramine were administered. Three days later, larvae started coming out of her nose and mouth. In total 10 larvae were documented. In emergency services at a hospital, physical examination revealed pharyngeal erythema and rinorrhea. The larvae were described as yellowish, 10 mm long and 3 mm wide. The worms were sent to the Department of Parasitology of the School of Medicine of Puebla, Mexico, where they completed the in vitro cycle and were identified as Dermatobia hominis (fly), belonging to the Enterebridae family. In the hospital, 85 larvae were extracted from the patient. She discharged after 10 days of asymptomatic hospitalization.
Conclusion. Myasis is not frequent and it can cause great tissue destruction. Antibiotic administration is generally not warranted unless there is evidence of concomitant superinfection.
