Overview
Chondrodermatitis nodularis chronica helicis (also known as "Chondrodermatitis nodularis helicis"[1]:782) (CNH) is a small, nodular, tender, chronic inflammatory lesion occurring on the helix of the ear, occurring most often in men.[2]:610
Pathophysiology
- The pathophysiology remains unclear. It may be due to chronic pressure or trauma or temperature changes or actinic damage to the ear. Prolonged pressure seemed to most commonly reported. Sleeping on the one side can cause this pressure.
- Other causes can be continuous use of headphones/ ear phones, hearing aids, or can be idiopathic. There are some theories on association with autoimmune disorders and connective tissue diseases like scleroderma, autoimmune thyroiditis, lupus erythematosus, or dermatomyositis.
- CNH is seen mostly in elderly men. There are cases seen in women and young, especially when associated with autoimmune or connective tissue disorders. [3] [4][5][6]
