Lobomycosis is a chronic skin mycosis endemic in Amazon regions characterized by chronic nodular or keloidal lesions caused by , an uncultivable fungus. Imported cases in nonendemic countries are rare and diagnosed after years. We describe a case of lobomycosis in a healthy 55-year-old Italian traveler who had acquired the infection during 5-day-honeymoon in the Amazon region of Venezuela in 1999. Several weeks after return, he recalled pruritus and papular skin lesions on the left lower limb, subsequently evolving to a plaque-like lesion. Blastomycosis and cryptococcosis were hypothesized based on microscopic morphology of yeast-like bodies found in three consecutive biopsies, although fungal cultures were always negative. In 2016, exfoliative cytology and a biopsy specimen examination showed round yeast-like organisms (6–12 μm), isolated or in a chain, connected by short tubular projections fulfilling the morphologic diagnostic criteria of spp. The microscopic diagnosis was confirmed by molecular identification.
