Sporotrichosis: Symptoms & Signs

Medically Reviewed on 1/8/2022

Sporotrichosis is a fungal infection found throughout the world. The condition has been referred to as rose gardener's disease.

The first sign of sporotrichosis is usually a small bump on the arm, finger, or hand that develops 1 to 12 weeks after exposure. The bump becomes larger and resembles a sore or ulcer. Immunosuppressed people can develop more widespread infections including pneumonia. If this occurs, symptoms can include cough, fever, chest pain, and shortness of breath.

Cause of Sporotrichosis

Infection with the fungus Sporothrix schenckii causes sporotrichosis. The infection usually begins when the fungus comes in contact with skin cuts or scrapes while gardening or handling vegetation (moss, hay, wood, sharp-stemmed plants like rosebushes).
