Hi,
Welcome to ehealthforum,
Sporotrichosis is caused by a fungus Sporothrix schenckii, which is found in vegetation. Infection occurs when the skin is broken while handling plant materials such as rosebushes, briars, or mulch-rich dirt. Symptoms include a small, painless, red lump that develops at the site of infection that eventually turns into an ulcer. Sometimes, the lump is known to develop up to 3 months after an injury. The fungus follows lymphatic channels in the body, so, small ulcers appear in lines on the skin as the infection goes up an arm or leg, and do not heal unless they are treated and may remain for years.
The skin infection (once diagnosed) is usually treated with an antifungal medicine called itraconazole which is taken by mouth and continued for 2 to 4 weeks after the skin lesions have cleared. Your doctor may recommend you to take the medicine for 3 to 6 months. Fluconazole is usually used in patients who do not respond to treatment with itraconazole, or have widespread lesions. You can consider taking a second opinion for your condition. If the diagnosis is not confirmed, you can also go ahead with getting treatment for the cat bite alone (usually treated symptomatically).
Take care.
