Abstract

A 21-month-old girl developed a local skin reaction after the unheated liquid contents of a broken lava lamp were in contact with her skin overnight. Several weeks later, small umbilicated erythematous papules containing central keratotic spines developed within the affected areas. Biopsy showed a granulomatous foreign body reaction with focal transepidermal elimination. Electron microscopy and energy-dispersive X-ray spectroscopy analysis of the tissue revealed carbon-based material, consistent with substances reported to be present in lava lamp liquid.
