Mycetoma-like infection caused by previously undescribed bacterium.

A 56-year-old man had a verrucous plaque with draining abscesses on the dorsum of hir foot for four years. Examination of cultures revealed a Gram-negative bacterium that, to our knowledge, has not been described in the literature. The infection was cured by treatment with co-trimoxazole (trimethoprim and sulfamethoxazole) and topical 10% lactic acid in hydrophylic emulsion base.
