Y1 - 2013 N1 - T2 - The Color Atlas of Family Medicine, 2e AB - A 44-year-old white man presents with a painful nodule on his right ear for 1 year (Figure 29-1). He has a long history of occupational sun exposure but no skin cancers. He states that it is too painful to sleep on his right side because of the ear nodule. He tried to remove it once with nail clippers but it bled too much. The patient is told that this is likely a benign condition called chondrodermatitis nodularis helicis. A shave biopsy/removal is performed for diagnostic and therapeutic purposes. It is explained to the patient that this could be a skin cancer as a result of his sun exposure history. The biopsy confirms chondrodermatitis nodularis helicis and he is counseled to use sun protection.
