ABSTRACT We report the case of a woman who complained of intense pruritus on the upper and lower lids of both eyes and severe erythema that appeared after scratching. In the interview, the patient reported that these injuries were caused by "bugs and worms that were in her skin and around her eyes. The bugs bit her and forced her to scratch her skin in order to get them out". There was no evidence of parasitic infestation. The psychological examination revealed the presence of delusions of parasite infestation and Delusional Parasitic Infestation was diagnosed. The Delusional Parasitic Infestation, also known as Ekbom syndrome, is classified within the Caroline Koblenzer’s strictly psychiatric skin conditions, in which the patient has a delusion of being infested by insects, worms or lice that inhabit and damage the skin. In most cases, the prognosis is favorable and the disorder has good response to risperidone, as long as the affected patients are adequately treated in a multidisciplinary manner by dermatologists and psychiatrists with expertise in this disease. Key word´s: pruritus, erythema, parasitic infestation, delusions, risperidone.
