The term sporotrichosis is used to designate a parasitic disease due to an infection by a species of Rhinocladium, and usually characterized by the presence of various-sized subcutaneous nodes and nodules with an associated lymphangitis. These nodular formations undergo various degrees of structural change. Some soften, enlarge and involve the overlying skin in an ulcerative process, while others undergo spontaneous healing.
Since the year 1898, when Schenck first described his case and the casual organism was classified as Sporotrichum, the literature has gradually grown, as to both the number of cases and the variety of related organisms of the same species which have shown themselves possessed of pathogenic qualities. Today sporotrichosis ranks as one of the more important, as well as one of the more frequent, of the major dermatomycoses. This right to importance is augmented by the close resemblance between sporotrichosis and syphilis and tuberculosis, both clinically and anatomicopathologically.
