Abstract and Introduction

Asymmetric periflexural exanthema of childhood is a benign, self-limiting disease of unknown origin. Patients generally present a few weeks after a viral-like prodrome with erythematous macules and papules within flexural spaces followed by centrifugal spread. Treatment focuses on alleviating symptoms of pruritus.

A 22-month-old boy came to the dermatology clinic with a mildly pruritic rash present for 6 days (see Figure 1). The eruption began initially near his left axilla and over a period of 10 days it extended onto the inner aspect of his left arm as well as downwards on the left side of the chest and abdomen (see Figure 2). The patient's mother noted no improvement after continuous application of over-the-counter topical corticosteroids. Approxi mately 3 weeks prior to presentation, the child had an upper-respiratory infection that resolved without specific treatment. This patient was asymptomatic. The child had a brief period of fever not exceeding 38.5C.

Erythematous eruption consisting of coalescent papules and macules involving the left axilla, the left lateral side of the chest, and the left arm.

Note the sparing of other areas on the right side of the body.
