[Accidental genital myiasis by Eristalis tenax].

Myiasis is a parasitic infestation of human or animal skin, necrotic tissues and natural cavities by fly larvae or pupa. In this paper we will describe the case of a 27 years old woman, asymptomatic, that spontaneously eliminated from her vagina two Eristalis tenax larvae, a worldwide distributed fly specie, classified as an accidental myiasis agent. The patient lived in an urban area, she had low socioeconomic status and she had the antecedent record of use of intravaginal vegetables as sexual stimulator. Analyzing the case and the references, we concluded the patient had an accidental infestation by E. tenax, being the vaginal introduction of vegetables the most probable mechanism of transmission. This kind of infestation has not been communicated in the literature. Also, this is the first documented case of E. tenax myiasis in Chile.
