Sutton's summer prurigo: a morphologic variant of atopic dermatitis.

We describe in detail 6 of 18 children affected by a recurrent summer papular eruption on the elbows, knees, and backs of the hands. In all six, family history, clinical observation, or laboratory data revealed signs of atopy. Phototesting, performed to evaluate the role of ultraviolet rays in the pathogenesis of the disease, gave results similar to those obtained in subjects with atopic dermatitis. Therefore we suggest that this disease may be a peculiar morphologic variant of atopic dermatitis.
