Overview
Sporotrichosis may be classified, according to the location of the lesions, into three subtypes: cutaneous, mucosal, and extracutaneous.
Classification
- Presentations vary based upon numerous factors, such as the patient’s immunological status, the severity and depth of the inoculum, and the particular strain’s thermal zone of tolerance and pathogenicity.
Cutaneous Forms
Cutaneous forms of Sporotrichosis typically manifest following minor epidermal trauma.
Fixed form:
- Staying localized within the subcutaneous tissue, the fungus transforms into its yeast form.
- Manifests at the site of inoculation with at least one, frequently ulcerated, lesion. The lesions are characterized by red edges due to capillary dilation and congestion.
- Fixed form sporotrichosis may spontaneously regress [1]
Lymphocutaneous form:
- The yeast form of S. schenckii extends through the nearby lymphatic vessels.[2]
- Approximately 70% of the cases of sporotrichosis may be classified as lymphocutaneous sporotrichosis.[3]
Disseminated cutaneous form:
- The hematogenous dissemination of the yeast form of "S. schenckii".
Mucosal Form
Extracutaneous Form
