Diagnostic Considerations

A clinically distinctive feature of chondrodermatitis nodularis chronica helicis (CNH) is that very often the patient presents for help because of the pain associated with the skin lesions. In contrast, cutaneous tumors in the differential diagnosis are usually painless, even when ulcerated. Consistent with this observation, Cribier et al found histologic evidence of nerve hyperplasia or increased numbers of small nerves adjacent to the involved cartilage primarily in chondrodermatitis nodularis chronica helicis cases but not in control tumors.
