Sporotrichosis

Sporotrichosis is a cutaneous fungal infection with a global distribution. The disease has several clinical forms, primarily cutaneous with associated lymphadenopathy. However, dissemination to osteoarticular structures and viscera may occur, both in healthy and immunosuppressed individuals; such disseminated forms usually follow spread after inhalation of fungal spores. Cutaneous infection is usually associated with trauma during the course of outdoor work, and treatment is required for the majority of patients. Potassium iodide (the treatment of choice in endemic areas) is an effective and inexpensive therapy; however, its adverse effects and complicated dosage regimen often weigh against its use in developed countries, where itraconazole is the antimycotic of choice.
