Sporotrichosis is a polymorphic disease caused by the fungus Sporothrix schenckii, which manifests mainly in the lymphocutaneous form, skin-fixed form, skin-disseminated form and sometimes with extra-skin form, affecting bones, joints, lungs and central nervous system. Objective: Investigate the occurrence of the disease in the population of Baixada Fluminense region. Material and methods: the lesion's material suggestive of sporotrichosis of 13 patients was collected and sent to a clinical pathology laboratory where it was grown in Petri dishes containing Sabouraud dextrose agar medium. The dishes were sealed and stored at room temperature. The obtained fungal growth was identified by analysis of the morphological characters. Result: The results confirmed the identity of S. schenckii of the 13 samples. Conclusions: lymphocutaneous form was the most frequent with lesions on the face and upper limbs. The contact with infected cats was considered the main mechanism of transmission of the etiologic agent among the studied patients. Treatment with itraconazole and potassium iodide was effective and well tolerated.
