Abstract:
A 51-year-old man had small, tender, skin colored firm nodule on the helix of the both ears for eight months. He was found to have classic features of chondrodermatitis nodularis chronica helicis, namely, tender nodule less than 1 cm in length with central crusting, localization to helix, age, men, and histologic findings. The histologic examination of the biopsy specimen showed the presence of thinned epiderrnis on center. acanthosis on the adjacent epidermis, with hyperkeratosis and parakeratosis, and cleft between epidermis and dermis. In the dermis, highly vascularized connective tissue and chronic inflarnmatory infiltrate were visible with perichondrial fibrosis. Elastic tissue stain showed degeneration of elastic fibers. After complete excision, no recurrence was obsered until now.
