Weathering nodules of the ear: a clinicopathological study

Twenty-five cases of distinctive ear nodules on the helices of the ears in elderly males are presented. We believe the clinicopathological features of these lesions allow them to be defined as a distinct entity. They are probably more common than is currently recognized. Histologically, a typical nodule comprises a spur of fibrous tissue with a focus of cartilage metaplasia. While the pathogenesis of weathering nodules remains unclear, there is an association with age and chronic UV exposure.
