Chondrodermatitis nodularis helicis (Chondrodermatitis nodularis chronica helicis) is considered to be an idiopathic degenerative process involving the upper dermis of the auricular rim.

The lesion is characterized by the presence of small, intensely painful nodules on the free border of the helix of the ear with unknown origin.

Patients are generally middle-aged or elderly males.

There are no associated systemic disorders with this condition.

Associations of Chondrodermatitis nodularis helicis with underlying trauma and sun exposure have been postulated as potential inciting factors.

The lesions are discrete, grey to red in color, oval shaped with raised rolled edges, and a central ulcer or depression which often contains a crust or scale.

The characteristic histopathologic features are epithelial hyperplasia, collagen degeneration, focal fibrinoid necrosis, and inflammatory components.

The differential diagnoses for chondrodermatitis nodularis chronica helicis are relapsing polychondritis and idiopathic cystic chondromalacia.
