What Is Sebaceous Hyperplasia?

Sebaceous hyperplasia is characterized by 1 or more small, yellowish, soft papules over the nose, cheeks, and forehead. It is a benign condition of sebaceous glands in middle-aged adults and older. Sebocytes (sebaceous cells) overcrowd the sebaceous gland, causing its enlargement that results in hyperplasia. Sebaceous hyperplasia lesions produce very little sebum.
