DEAR EDITOR, A 53-year-old man presented with a 2-month history of (a) erythematous papules and plaques on the nose root, and two abscesses on (b) the neck and (c) the left face, with cervicofacial lymphadenitis. Skin biopsy of the plaques revealed (d) granulomatous inflammation with multinucleated giant cells. (e) Mycobacterium marinum was isolated and confirmed by DNA sequencing. All lesions regressed completely after 3-month treatment with rifampin, ethambutol and minocycline. Mycobacterium marinum infection rarely involves the face. This patient reported an accidental scratch on the nose root by a rusty shrimp cage prior to the lesions’ onset, providing a key diagnostic clue. H. FENG Y. SU S . FU iD Y. ZHOU R. X IAO R. WU X.
