Why is sporotrichosis itchy?

Sporotrichosis is caused by the fungus Sporothrix schenckii, which can lead to dermatitis and inflammation upon infection. The itchiness associated with sporotrichosis is primarily due to the body's immune response to the fungal invasion, resulting in histamine release and irritation of nerve endings in the skin. Additionally, the formation of lesions and the body's efforts to heal can further contribute to the sensation of itchiness.
