Disseminated Legionella micdadei infection in a liver transplant patient presenting as pulmonary nodules and a laryngeal lesion.

We report a liver transplant patient with disseminated Legionella micdadei infection with pulmonary, laryngeal, and suspected muscle involvement. This organism, which stains weakly acid-fast, primarily affects immunocompromised patients. The diagnosis is difficult to make; in this case, the organism was identified via molecular diagnostics on laryngeal and pulmonary biopsy tissue.
