Abstract
Three patients with neuritis of the great auricular nerve (GAN) have been reported. Two patients seen by physicians and an otolaryngologist had prominent and tender cord along the neck with facial edema and history of fainting attack in one, and erythema and hyperaesthesia of the ear in the other simulating vascular occlusion, which were confirmed to be leprosy in Type 1 reaction by the dermatologist. In the third, cold abscess in the nerve that had persisted after anti-leprosy treatment was mistaken as tuberculous cervical lymphadenitis by a surgeon since aspiration had revealed acid-fast bacilli. The probable reasons for misdiagnosis include rarity of involvement of the GAN and its proximity to main blood vessels, and the need for careful interpretation of laboratory results.
