Of 191 children who had had infantile seborrheic dermatitis, 88 were r
eexamined after 10 years. One child had psoriasis, four had atopic der
matitis, and seven had seborrheic dermatitis, which suggests a link wi
th adult seborrheic dermatitis. A familial tendency toward infantile s
eborrheic dermatitis was noted, as was an increased incidence of aller
gy within the family.
