Case 9

A 60-year-old horticulturist complains of a painful papule on his ear, which prevents him sleeping on the affected side.

Chondrodermatitis nodularis helicis chronicum et dolorum (CNH)

Basal cell carcinoma, squamous cell carcinoma, gouty tophus, chilblain, perichondritis, polychondritis, elastotic nodules

The treatment of choice is excision. Pressure on the affected area must be avoided long term. The patient should sleep on the unaffected side, or use a pillow with a hole cut in it for the ear. Recurrence of CNH is common following minor trauma eg: sleeping on the ear. Intralesional steroid injection may help early lesions.
