Concurrent Appearance of Alopecia Areata in Four Siblings / 대한피부과학회지

ABSTRACT

Familial occurrence of alopecia areata is not uncommon. A positive family history ranging among 10% to 40% has been reported from different surveys. A prevalence of 3% has been observed among siblings. The simultaneous onset of the disease in four siblings is, however, rare. We report the concurrent appearance of alopecia areata in four siblings and suggest emotional and genetic factors as possible causes.
