Roentgenology of sporotrichosis.
Localized cutaneous as well as unifocal and multifocal systemic sporotrichosis may all produce roentgenographic findings. Localized cutaneous nodules may occasionally extend to the bone below producing a locally erosive lesion similar to those more commonly found in blastomycosis. More frequently, sporotrichosis involves the joints, either alone or with accompanying skin nodules. The joint changes are those of a pyogenic arthritis of the knees, elbows, hands, or feet which is difficult to distinguish from pyarthrosis produced by other organisms. The pulmonary findings depend upon whether or not the lung is the only site of infection. If there are no other areas of involvement, the pulmonary findings may be indistinguishable from those of secondary tuberculosis. However, if the skin on joints are also involved, small nodules appear and apparently do not proceed to cavitation.
