Abstract
- Weathering nodules are benign skin conditions of the ear typically occurring in patients with a history of persistent sun exposure. Clinically, they appear as multiple localized, skin-colored to whitish papules or nodules in the ear helix. Histopathologically, weathering nodules are characterized by chondroid metaplasia with spurs of fibrous tissue extending upward from the disrupted perichondrium of the underlying pinna cartilage. We report the case of a 19-year-old man who presented with multiple localized whitish papules on the right ear helix for a month. The lesions were asymptomatic and accompanied by a blanch sign. Histopathological examination revealed chondroid metaplasia in the dermis, separate from the pinna cartilage. Based on the clinicopathological findings, weathering nodules of the ear was diagnosed.
