Sporotrichosis is an infection of the skin caused by a fungus. At home, all you can do is to keep the ulcers clean and covered while they heal.
Treatment of sporotrichosis depends on the site infected.
If the infection is only in the skin, the usual treatment uses a saturated potassium iodide solution. This medicine is given 3 times a day for 3 to 6 months until all the lesions have gone away. Skin infections may also be treated with itraconazole (Sporanox) for up to 6 months.
