Epidemiology, clinicopathology, and diagnosis of cutaneous nocardiosis: A case series and population-level analysis

Cutaneous nocardiosis is a rare, opportunistic infection that occurs secondary to systemic disseminated infection or as a primary infection following direct penetration of the skin by Nocardia, often from contaminated soil.1 Distinct clinical presentations of cutaneous nocardiosis include superficial skin infection, lymphocutaneous infection, and actinomycetoma. Cutaneous nocardiosis presents variably and mimics other cutaneous infections including sporotrichosis, tuberculosis, atypical mycobacteria, leishmaniasis, and syphilis.
