A Wood UV lamp is useful in a wide variety of primary care settings. Seen in "black light," fungi appear bright yellow-green to pale green, Corynebacterium minutissimum looks coral red to pink, Pseudomonas aeruginosa appears as aqua-green to whitish green patches, and Malassezia furfur is golden yellow. A Wood lamp can also be used to evaluate pruritic papules for scabies and to check for abrasions and herpetic lesions of the cornea (after staining).
