ORPHA:826Disease
What it is
Sporotrichosis is an infection caused by the dimorphic fungus Sporothrix schenckii, generally occurring by traumatic inoculation of fungus from contaminated soil, plants, and organic matter, that has a highly variable disease spectrum but that usually presents as a subcutaneous mycosis with a single sporotrichotic chancre that may ulcerate and can then progress to lymphocutaneous (most common form; sporotrichotic chancre at inoculation site and a string of similar nodules along the proximal lymphatics), fixed cutaneous (localized asymptomatic, erythematous, papules at the inoculation site), or multifocal or disseminated cutaneous (rare form, with 3 or more lesions involving 2 different anatomical sites) forms. Pulmonary sporotrichosis occurs following inhalation of fungus and manifests as chronic pneumonitis while extracutaneous or systemic sporotrichosis (with osteoarticular, pulmonary, and central nervous system/meningeal disease) has also been reported, usually occurring in the setting of immunosuppression.
