Primary demodicosis is an illness sui generis. Secondary demodicosisis usually connected with some form of organism´attenuation. Lesions are present mostly on a face, eye lids and in earcanals. For setting a diagnosis mostly only anamnesis and clinical checkup are enough. In unclear cases a microscope investigation,exceptionally a histopathological verification are necessary.
