A Report of 10 Individuals with Weathering Nodules and Review of the Literature.

Weathering nodules are a benign skin condition that usually present as papules on the helices of patients with significant prior sun exposure. They are easily recognized clinically and blanch upon application of pressure to the adjacent helical rim: a positive blanch sign. We describe the clinical presentation of weathering nodules in 10 patients, nine men and one woman, aging from 38 to 70 (median 59), and their associated risk factors. Eight patients had a history of actinic keratosis, three had a history of nonmelanoma skin cancer, and all patients had increased Sun exposure through outdoor activities. Weathering nodules are rarely mentioned in the literature and may be confused with other cutaneous disorders. Therefore, it is paramount for clinicians to become familiar with weathering nodules and include them in the differential diagnosis of ear nodules. Appropriate diagnosis will help avoid unnecessary biopsies while reassuring the patient that the lesions are benign.
