title: Naevus comedonicus in homozygous twins.
abstract: This is the first case report of bilateral naevus comedonicus seen in a pair of twins in Singapore. 3 other family members were similarly affected. Though both sexes were affected, there were more males affected as compared to females. Recent reports support a familial inheritance. Our pedigree showed an autosomal dominant inheritance. The extensive involvement seen in the twins suggest that they may be homozygous for this condition.
