Rosacea Found 'Not Uncommon' in South Korea
While acknowledging that rosacea is more widespread among fair-skinned individuals, researchers found that rosacea is "not uncommon" in Korea, according to information presented at the annual meeting of the American Academy of Dermatology.
Rosacea was diagnosed in about 1 percent of nearly 6,000 patients who visited the clinic of Drs. B. J. Kim, J. M. Park, J. N. Park and W. S. Koh of the Department of Dermatology, Inje University College of Medicine, Sanggye Paik Hospital in Seoul, South Korea.
They noted that flushing and redness (erythema) occurred at high rates when compared with a similar study in England. On the other hand, they reported that papules (bumps), pustules (pimples) and rhinophyma (enlarged nose) were less common in the Korean patients than in the English study.
The researchers said papules, pustules and rhinophyma may be rarer in Korea due to less sun-induced degeneration of connective tissue because of more pigmentation in Koreans than in Caucasians.
About two-thirds of the Korean rosacea sufferers were women. Interestingly, the Korean researchers reported no cases of ocular rosacea (eye irritation), which has been found at significant rates in Western studies.
