Sporotrichosis is a subacute or chronic mycosis caused by the dimorphic fungus Sporothrix schenckii which is endemic in Brazil and is transmitted primarily through traumatic inoculation of its causative agent into the skin. The zoonotic transmission, especially from infected cats, has been demonstrated in several reports and case series. We present simultaneous occurrence of the disease in three members of the same family by scratches from an infected domestic cat. Two patients developed the lymphocutaneous form and one only developed the fixed cutaneous form. Two patients were successfully treated with saturated solution of potassium iodide; however, the third case reported side effects and had his therapy substituted for itraconazole, with resolution of his lesions
