Chondrodermatitis nodularis chronica helicis (CNCH), Winkler's disease, pressure, nodule, excision, recurrence.
Chondrodermatitis nodularis chronica helicis (CNCH) is a cutaneous lesion of the external ear characterized by spontaneously evolving tender nodule over the apex of helix or antihelix.
Chondrodermatitis nodularis helicis (or antihelices depending on site of lesion), chondrodermatitis nodularis chronica helicis, ear pressure sore, painful nodule of the ear, Winkler's disease.
Analysis of the excised specimen detected epidermal ulceration with foci of necrosis in the hyaline cartilage, focal granulation tissue, and epidermal hyperplasia and hyperkeratosis; these findings were consistent with chondrodermatitis nodularis chronica helicis.
Once malignancy is ruled out and a histologic diagnosis of chondrodermatitis nodularis chronica helicis is reached, the patient can be treated surgically or medically.
