Resumen

CALDERON H, Perla; ROJAS E, Camilo; APT B, Werner  y  CASTILLO O, Douglas. Cutaneous myiasis due to Cochliomyia hominivorax associated with seborrheic dermatitis. Rev. méd. Chile [online]. 2017, vol.145, n.2, pp.250-254. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872017000200013.

Myiasis is an infestation of tissues and organs of humans and animals by Diptera larvae (flies, horseflies, mosquitoes). They are located at different body sites, and classified clinically as cutaneous, visceral and cavitary. We report a 26-year-old woman with a history of seborrheic dermatitis and recent trip to Brazil. She presented with a seven days history of suppurating wounds in the parieto-occipital area of the scalp. At physical examination we found three ulcers of approximately 1.5 cm each, with multiple mobile larvae inside. The obtained larvae were analyzed, identifying Cochliomyia hominivorax larvae at L2 and L3 stages. The patient was managed successfully with oral antimicrobials and local cleansing. The screwworm Cochliomyia hominivorax in our country is rare. Known risk factors are wounds, poor personal hygiene, extreme ages, psychiatric disorders, presence of specific dermatosis such as psoriasis and seborrheic dermatitis, among others.
