A chronic cutaneous mycosis spread by way of the lymphatics and caused by inoculation of Sporothrix schenckii, typically rare in tissue sections but rapidly growing in cultures. Extracutaneous s. probably originates in the lung but disseminates to cause osteoarticular or other visceral disease. Chronic cavitary lung disease is another manifestation. SYN: Schenck disease.

spo·ro·tri·cho·sis (spor″o-trĭ-koґsis) [sporo- + trich- + -osis] chronic fungal infection with Sporothrix schenckii; in most species it is characterized by nodular lesions of the cutaneous and subcutaneous tissues and adjacent lymphatics that suppurate and ulcerate. It is acquired by fungal implantation into the skin by trauma or through an abrasion, or by inhalation into the lungs. The infection may remain localized or may be disseminated by the bloodstream to involve the osteoarticular and musculoskeletal tissues, viscera, mucous membranes, central nervous system, eye, or genitourinary system.Medical dictionary. 2011.
