This young boy exhibited a verrucous, or wart-like lesion on the tip of his nose, which was diagnosed as a case of sporotrichosis, due to the fungal organism, Sporothrix schenckii. See PHIL 16793, for another view of this child’s condition.
“Sporotrichosis is an infection caused by a fungus, Sporothrix schenckii. The fungus lives throughout the world in soil, plants, and decaying vegetation. Cutaneous infection is the most common form of infection and usually occurs after handling contaminated plant material, when the fungus enters the skin through a small cut or scrape.”
