A Case of Bilateral Chondrodermatitis Nodularis Chronica Helicis on Both Helices Treated with Intralesional Steroid Injection / 대한피부과학회지

We report a case of bilateral chondrodermatitis nodularis chronica helicis, on both helices, in a 60-year-old male patient. He presented with a 1-year history of two tender, firm, dark-brownish, 0.4x0.4cm-sized nodules with central ulceration on both helices. He had no history of trauma. A punch biopsy specimen taken from the nodule revealed central ulceration, hyperkeratosis, and irregular acanthosis of the epidermis. Within the dermis, there was inflammatory cell infiltration, dilatation and proliferation of vessels, and some eosinophilic collagen degeneration associated with degenerative cartilage. Based on these clinical and histologic findings, we diagnosed this as a rare case of bilateral chondrodermatitis nodularis chronica helicis occurring on both helices. We treated the lesions with intralesional steroid injections.

A Case of Bilateral Chondrodermatitis Nodularis Chronica Helicis on the Concha of Auricles / 대한피부과학회지

Chondrodermatitis nodularis chronica helicis is a painful erythematous, often crusted, papule most commonly found on the helix of the ear of men over the age of 40 years. It is seen less commonly in women, in whom it is usually located on the antihelix. The lesions usually occur unilaterally, although bilateral involvement has been reported. We report an unusual case of chondrodermatitis nodularis chronica helicis in an 86-year-old woman, which presented with bilateral involvement of the concha of auricles.
