Hidradenitis suppurativa in South-East Asia and East Asia.

ABSTRACT

Hidradenitis suppurativa (HS) in South-East Asia and East Asia shows distinct clinical, environmental, physiological and likely genetic differences compared with the West. A male predominance is present, which may be due to differences in smoking habits. Involvement of the buttocks is common in East Asian patients, while the axillae are most commonly affected in South-East Asian patients. Metabolic comorbidities are prevalent in South-East Asian and East Asian HS patients. A family history of HS is less common than noted in Western populations. Asian ethnic subgroups deserve further study.
