Sporotrichosis on the hand and arm
Sporotrichosis is a fungal infection that frequently occurs following a minor injury while gardening or farming. Spores, which live in vegetation, enter the skin and begin to grow. The fungus follows the lymph channels up the extremity. Granulomatous lesions develop along the lymph channel, ulcerate, and drain. If left untreated, this condition can persist for years.
