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


Historical Perspective[edit | edit source]

  • Chondrodermatitis nodularis chronica helicis was first discovered by Max Winkler, a dermatologist, in 1915, in a paper titled Knötchenförmige Erkrankung am Helix . [3][4]
  • in 1925, Foerster further developed the clinical, microscopic and treatment options for CNH.

Pathophysiology

  • The pathophysiology remains unclear. It may be due to chronic pressure or trauma or anatomic features or temperature changes or actinic damage to the ear. Prolonged pressure seemed the most commonly reported cause. Sleeping on the one side can cause this pressure.
  • Other causes can be continuous use of headphones/ ear phones/ cell 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 few cases seen in women and young, especially when associated with autoimmune or connective tissue disorders. [5][6][7][8]
  • The anatomy of ear pinna can contribute to the pathophysiology of CNH. The pinna has limited blood supply and little subcutaneous tissue, which easily lead to formation of sore with pressure or trauma or cold temperature. [9]
  • In 2009, Perichondrium vasculitis theory explained above anatomical features. Because of the vasculature and subcutaneous tissue padding limitations, there is easy development of ischemia and necrosis of underlying cartilage, causing a severe inflammatory condition, leading to CNH. [10][11]
