Dermatitis by Cheyletus eruditus in man

The Cheyletidae mites are known to cause injuries in animals, but their presence causing skin diseases in humans is not often reported. These diagnoses can be difficult because of the small size of the mites (0.2 to 1.6mm) and the lack of an investigation of the environment, often resulting in misdiagnosis. This paper aims to describe the presence of a Prostigmata mite, of the Cheyletidae family, Cheyletus eruditus parasitizing humans in a residence in the central region of the state of Rio Grande do Sul, Brazil.
