Cheyletidae mites are of great importance in the veterinary sciences, as they are associated with parasitism in birds and mammals. Yet they are barely studied as etiological factors to human dermatitis in spite of being referred to since the beginning of the 20th century. The authors propose to analyze a clinical case of dermatitis caused by mites of the Cheyletidae family in a six-month old patient. The discovery of three species of that family in the patient's domiciliary ecosystem, associated to the cutaneous manifestations correlated with its definitive cure after this environment was sanitized, leads the authors to believe in the need to consider this diagnostic hypothesis for human dermatitis
