Definition:

Sporotrichosis is an endemic mycosis in tropical and subtropical areas caused by Sporothrix schenckii which is a common saprophyte of soil, decaying wood, hay and sphagnum moss. S. schenckii usually causes a mixed suppurative and granulomatous inflammatory reaction in the dermis and subcutaneous tissue, frequently accompanied by microabscess and fibrosis. The most common symptom is cutaneous disease, which is classified into fixed and lymphocutaneous forms. Osteoarticular, pulmonary, mucosal, disseminated and systemic infections are less common and usually occur in immunosuppressed individuals.
