Atopic background of a recurrent papular eruption of childhood (frictional lichenoid eruption).

Thirty-five children affected by a recurrent summer and spring papular eruption on the elbows, knees, and backs of the hands were examined retrospectively in order to evaluate the frequency of atopy. It was found that 45.7% were suffering from atopic diseases (atopic eczema, allergic rhinitis, asthma). This high proportion confirms the fact that an underlying atopy may predispose to the occurrence of this dermatosis.
