Characteristics include frequent blushing, red papules and papules on the face, telangiectasia and involvement of the nose as in rhinophyma. However, you will not see comedones in rosacea like in the case for our patient. Oral herpes simplex infections should be considered when there are recurrent lesions around the mouth that have a grouped vesicular appearance.
