Transilluminator burns in the neonatal intensive care unit: a mimicker of more serious disease.

We report an outbreak of erythematous to purpuric papules and vesicles in four neonates whose lesions arose within a 72-hour period in a neonatal intensive care unit. As isolated lesions, the clinical presentation mimicked cutaneous aspergillosis. Ultimately, because of the number of patients with similar lesions, an exogenous source was suspected and determined to be a faulty transillumination device.
