Sporotrichosis transmitted by domestic cats: A case report

Sporotrichosis is a subacute to chronic subcutaneous mycosis caused by dimorphic fungi of the Sporothrix spp. complex. It is considered the most frequent subcutaneous mycosis in Latin America and predominates in tropical areas. In Argentina, its prevalence is estimated at 0.01-0.02%. In half of the patients, it manifests as lymphocutaneous sporotrichosis. Infection results from the agent's inoculation on the skin or mucous membrane by trauma with contaminated plants. There are also cases of zoonotic transmission by contact with animals, such as armadillos, birds, rats, horses, fish, mosquitoes, and cats. Here we describe the case of a 14-year-old female patient who consulted due to nodular lymphangitic syndrome for two months and, given the lack of response to multiple antibiotic regimens, a biopsy was performed and a culture of the lesion was done, which confirmed the diagnosis of lymphocutaneous sporotrichosis.
