Clinical Medicine Insights: Dermatology

Objective: Presentation of chondrodermatitis nodularis helicis chronica that is an uncommon but important differential diagnosis for particular benign and malignant tumours.

Case report: A 32-year-old woman presented with a painful, hyperkeratotic nodule on her left antihelix. The lesion was treated with cryotherapy and resolved completely.

Conclusion: Chondrodermatitis nodularis helicis should be considered as an important differential diagnosis for skin tumours and cryotherapy may be a good alternative in selected cases with an excellent cosmetic outcome to the surgery although surgery is still the mainstay of the treatment of this condition.
