Sebaceous hyperplasia is a disorder that affects the sebaceous glands, where they become enlarged. These sebaceous glands are located within the skin and are responsible for secreting an oily substance called sebum. These glands are most commonly associated with hair follicles but they can also be found hairless regions of the skin as well. The secretions that come from these glands, lubricates the skin, protecting it from drying out or becoming irritated.
Sebaceous hyperplasia normally affects middle-aged to the elderly. Symptoms of this condition are 1-5 mm papule on the skin, mainly on the forehead, nose, cheeks, and sebarrhoeic skin. The papule my be cauliflower-shaped. Another symptom of this glandular disorder is acne. The acne that is associated with this disorder is not the same type of acne that affects adolescents and young adults. They look like more of an abnormally discolored patch that can’t be cured with topical treatments alone.
