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.
