Lymphocutaneous sporotrichosis.

Lymphocutaneous sporotrichosis presented in a 10 year old child 1-2 weeks after an abrasion. A series of nodules, two of which ulcerated, appeared along the arm with tender unilateral axillary lymphadenopathy in the absence of systemic symptoms. Biopsy showed a granulomatous infiltrate but failed to reveal the organism; however, culture was positive for Sporothrix schenckii. The primary lesion healed with a scar after 3 months of systemic therapy with potassium iodide.
