Abstract

Gamasoidosis is a poorly known and underdiagnosed mite infestation. It is characterized by the presence of erythematous and flattened papules that are quite pruritic, and can affect any region of the body, with preference for areas of folds. This article reports a case of the disease caused by mites of the species Dermanyssus gallinae. Increasingly, the agents that cause this disease are found in urban environments, increasing the incidence of people affected by the disease. This dermatosis has a self-limiting clinical picture and the treatment is done with the use of topical corticosteroids and oral antihistamines.
