Sebaceous Hyperplasia Information
Sebaceous hyperplasia is a common benign condition consisting of prominently enlarged, sebaceous glands on the face. Sebaceous hyperplasia occurs in both men and women. Papules rarely appear before age 30 but become increasingly more common with advancing age. Roughly 80% of patients over age 70 have at least one such lesion. Most lesions represent a single, hypertrophied sebaceous gland with multiple lobules arranged around a central enlarged sebaceous duct.
Lesions occur in all skin types but are more easily seen in lighter skin. The etiology of sebaceous hyperplasia is unknown. Genetic inheritance most certainly plays a large role. Sun damage has been suggested as a contributing factor. The lesions are entirely asymptomatic but persistent. Papules can become disfiguring and are mostly of cosmetic concern. Older patients are typically concerned that the lesions represent basal cell carcinoma or other type of skin cancer.
