Usually, sporotrichosis results from traumatic inoculation of Sporothrix spp. into the dermis, affecting humans and other mammals, but a greater number of cases have been reported in felines, a fact increasingly important in the zoonotic transmission of diseased animals to man. In horses, there may be multiple ulcerated wounds covered with scabs and slightly elevated plaques or nodules that occur along lymphatic chains in limbs and can be unique and located. Iodides are considered drugs of choice for the treatment of sporotrichosis in horses. The main side effect of prolonged use of these substances is iodism and thyroid dysfunction. The aim of this study was to report a clinical case of sporotrichosis in an equine treated in the state of Paraná, southern Brazil, which showed secondary iatrogenic hypothyroidism with prolonged use of sodium and potassium iodide. Case: A female, 3-year-old, Quarter Horse, with 400 kg of liveweight presented at clinical examination of the cutaneous tissue elevated lesions of nodular aspect, with 2 to 4 cm in diameter, absence of itching and some nodules presenting alopecia areas in the chest and abdominal region, and in the [...](AU)
