Vesicular eruption on the arm of an infant.

Cutaneous mucormycosis is an uncommon disease and occurs mainly in immunocompromised patients. We report an immunocompetent infant who developed primary cutaneous mucormycosis at an intravenous line site secured with an arm board and elastic bandage. The isolate was identified as the zygomycete, Rhizopus sp. High mortality rates are reported with invasive mucormycosis; however, early identification of the causative agent and antifungal therapy led to complete cure of the lesions in the reported case.
