A full term boy with bladder extrophy develolped a diffuse red urticarial papular eruption on the trunk that spread to the proximal extremities on day 2 of life. On day 3 of life 1-2 mm white papules and pustules formed at the center of the red papules that were most dense in skin creases and the diaper area. Smears of the contents of the pustules showed cellular debris, eosinophils and neutrophils, but no organisms. Cultures for fungus and bacteria from the pustules were also negative. Two days later the erythema was receding and pustules were dry and desquamating. Pediatric urology repaired the bladder extrophy without complication.
