We bring attention to the possible entity of otic rosacea. Just as patients with rosacea may develop ophthalmic rosacea, it should not be at all surprising if such patients could have otic rosacea. After all, several dermatoses including psoriasis and seborrheic dermatitis are known to affect the ear canals. It is suggested that an "otitis externa" in a patient with cutaneous rosacea should arouse the suspicion that the same condition could be occurring in the auditory canal.
