A 56-year-old Hispanic woman came to the office distraught about the red rash on her face. The rash has been on her cheeks and nose for 5 years, but over the past 2 weeks she has developed red, mildly pruritic, and very tender papules that she calls granitos (the Spanish term for pimples). Foods do not make the rash better or worse, but it gets redder with sun exposure. She had not tried any lotions or sought medical attention until now, when she noticed that the papules were increasing in number but not size.
A few years ago she first noticed small blood vessels becoming more prominent, especially on her cheeks. The lesions have not bled or ulcerated. Her health has been generally good within the past year, with no recent infections. Review of systems indicated no changes in vision, upper respiratory illness, or systemic conditions. She is being treated for type 2 diabetes and hypertension. She does not have a family history of the same rash. FIGURES 1 AND 2 show erythema and telangiectasias distributed symmetrically on both cheeks and nose. A cluster of smooth papules were seen under the nose. No scales were noted.
