Distinctive skin lesions with pale halos occurred in Hawaii. The asymptomatic, erythematous macules and papules, located on the face, upper extremities, and neck, resolved sponstaneously in a few days. Clinical and epidemiological evidence implicated thrips, a minute plant-eating insect, as the cause of these bizarre lesions. Thorough medical evaluation of several subjects showed them to be completely normal. Unfortunately, attempts to reproduce the lesions in volunteers were unsuccessful. Awareness of the benign nature of these lesions may prevent over treatment.
