SPOROTRICHOSIS is a chronic infection caused by the fungus Sporotrichum schenckii. The disease is found world wide and occurs in all age groups, but most frequently in adult men. Farmers, gardeners, laborers, and certain types of miners are most commonly affected. The organism gains entrance into the skin through a cut or wound made by an object contaminated with spores. Natural infection of rats, dogs, mules, and horses has been reported.
The most common type of sporotrichosis is the lymphatic, which begins at the site of the initial trauma, most frequently on an extremity. A nodule forms, breaks down to form a chronic ulcer, and within a few weeks, new subcutaneous nodules arise consecutively along the course of the regional lymphatics in a more or less linear fashion. These nodules break down consecutively.
Sporotrichosis may rarely occur in a hematogenous form, in which crops of subcutaneous nodules appear generally over
