Unusual clinical presentation of sporotrichosis in three members of one family

Introduction Sporotrichosis is a mycosis caused by the dimorphic fungus Sporothrix spp., and the primary mode of transmission is traumatic inoculation of fungus conidia from plants and other organic matter. Methods Sporotrichosis was established in a cat and in three members of one family from a rural area, by fungal growth in culture. Results The cutaneous lesions developed on the lower buttock and limbs with no report of any injury. Conclusion Although sporotrichosis should be considered for differential diagnosis in people working with soil and plants, cases of chronic lesions on skin of cats and in households is probably a new epidemiological approach in a given geographic region.
