Hypertrophic rosacea is a skin condition that causes thickening and inflammation of the skin. There are a few different synonyms for this condition, including rhinophyma, which specifically refers to thickening and enlargement of the nose, and granulomatous rosacea, which involves the formation of small, hard bumps on the skin. Other possible synonyms include nodular rosacea, papulopustular rosacea, and nodulocystic rosacea, all of which describe variations of the condition that involve the formation of bumps and pustules on the skin. While these terms may be used interchangeably, it's important to note that there can be slight differences in the presentation and treatment of each subtype of hypertrophic rosacea.
