Clinical evaluation of 368 patients with nasal rosacea: subtype classification and grading of nasal rosacea.

BACKGROUND

The clinical features of nasal rosacea have not been described in detail.

OBJECTIVE

To describe the clinical features of nasal rosacea.

METHODS

599 patients were classified into those with rosacea in both the nasal and extra-nasal areas (group A), localized nasal rosacea (group B) and rosacea without nasal involvement (group C).

RESULTS

The mixed subtype was more common in group A (n = 337) than in group C (n = 231). The severity score was higher in group A than in group C. Erythematotelangiectatic rosacea was the most common subtype in group B (n = 31) and was more common in group B than in group A. Rosacea mainly affected the lower half of the nose in group B, but affected the entire nose in group A.

CONCLUSION

Nasal involvement may be an index of severe rosacea. Localized nasal rosacea is a separate spectrum with different clinical features.
