Chondrodermatitis nodularis helicis usually presents as a raised nodule on the parts of the ear cartilage referred to as the “helix” or the “antihelix.” These are the inner and outer ridges of cartilage in the ear. If you notice that a painful nodule in your ear has appeared, you need to show it to your doctor.
Interestingly, most men present with lesions on the helix whereas most women and non-white men tend to have CNH nodules on the antihelix (Figure 4). Nodules are more common on the right ear, likely related to a higher prevalence of sleeping on the right side.

Chondrodermatitis nodularis chronica helicis (CNH) is a benign inflammatory condition that affects the skin and cartilage of the pinna. CNH, also known as Winkler disease, commonly affects the helix of the pinna, though in some cases, the antihelix also may be affected.

Otalgia is defined as ear pain. Two separate and distinct types of otalgia exist. Pain that originates within the ear is primary otalgia; pain that originates outside the ear is referred otalgia. [1, 2] Typical sources of primary otalgia are external otitis, otitis media, mastoiditis, and auricular infections.

The medical term for the outer ear is the auricle or pinna. The outer ear is made up of cartilage and skin. There are three different parts to the outer ear; the tragus, helix and the lobule. The ear canal starts at the outer ear and ends at the ear drum.
