Résumé
Abstract: Amicrobial pustulosis of the folds is a chronic relapsing neutrophilic dermatosis characterized by sterile pustules compromising skin folds, scalp, face and periorificial regions. It predominantly affects women. Demodicosis is an inflammatory disease associated with cutaneous overpopulation of the mite Demodex spp., the pathogenesis of which is not completely established, but is frequently related to local immunodeficiency. A case of a young woman with amicrobial pustulosis of the folds, and isolated worsening of facial lesions, is reported; investigation revealed overlapping demodicosis. There was complete regression of lesions with acaricide and cyclin treatment. This case warns of a poorly diagnosed but disfiguring and stigmatizing disease, often associated with underlying dermatoses or inadvertent treatments on the face.

La demodicosis es una patología cutánea crónica caracterizada por lesiones eritemato-maculares pruriginosas, cuyo agente causal son ácaros foliculares del género Demodex. Presenta un abanico amplio y polimorfo de manifestaciones clínicas, donde la sospecha clínica se presentará frente a una erupción facial crónica persistente o recurrente, resistente a terapia convencional y de distribución asimétrica. El diagnóstico definitivo es difícil, y requiere un cuadro clínico compatible y la presencia de alta densidad de Demodex. El siguiente documento hace una revisión de conceptos con respecto a la patogenia, clínica, diagnóstico y tratamiento de esta entidad.
Demodicosis is a chronic skin condition characterized by itchy erythematous macular lesions whose causal agents are gender follicular Demodex mites. This entity presents a wide and polymorphous range of clinical manifestations, in which clinical suspicion appears in case of persistent or recurrent chronic facial rash, resistant to conventional therapy and with an asymmetric distribution. The definitive diagnosis is hard to reach, and requires a compatible clinical picture and a high density of Demodex. The following document is a review of concepts regarding pathogenesis, symptoms, diagnosis and treatment of this disease.
