What condition is characterized by a red, bumpy nose due to skin changes?

The condition characterized by a red, bumpy nose due to skin changes is rhinophyma. This condition is a type of rosacea, specifically associated with thickening of the skin and enlargement of the sebaceous glands, leading to a rough, swollen appearance, particularly on the nose. Rhinophyma often presents as a pronounced redness and a bumpy texture, which gives it a distinct look that can be easily identified.

While rosacea in general may involve redness and flushing of the face, rhinophyma specifically refers to the development of the bulbous nose associated with advanced rosacea. This change is due to inflammation and changes in the skin structure over time, leading to the characteristic features of rhinophyma. Understanding this distinction is important when diagnosing and treating patients with facial dermatological conditions.
