Chondrodermatitis nodularis

Chondrodermatitis nodularis is a common condition in clinical practice but rarely discussed or reported in the literature. It most often affects the helices and antihelices of the ear. It is either uni- or bilateral. Injury usually initiates or triggers the disease. Microscopic pathology supplements the clinical diagnosis. Its etiopathogenesis points to this being a transepidermal elimination or perforating dermatoses.
