Rhinophyma is a large, bulb-shaped, red-colored (ruddy) nose.

Rhinophyma was once thought to be caused by heavy alcohol consumption, but this is not the case. Rhinophyma occurs equally in those who do not drink at all and those who drink alcohol in quantity. The condition is much more common in men than in women.

The cause of rhinophyma is unknown, though it is generally regarded as a severe form of rosacea. It is a relatively rare disorder involving thickening of the skin on the nose and the presence of many oil glands. The nose takes on a bulb-like (bulbous) look.

Symptoms involve an abnormal appearance of the nose:

• Thickening
• Bulb shape
• May be reddish
• Waxy, yellow surface

Rhinophyma may usually be diagnosed without any testing. A skin biopsy may be needed to confirm the diagnosis in unusual cases.
