Pseudomonas aeruginosa is a common causative agent of septicemia in compromised host and the entry site of organism is most commonly the respiratory and genitourinary tract. P. aeruginosa septicemia is often associated with vesicular or pustular skin lesions, subcutaneous nodules, deep abscess, cellulites and bullae. We report a case of P. aeruginosa pneumonia with multiple pustular skin lesions on the chest and leg. A 77-year-old male was admitted to our hospital complaining of fever, productive cough and eruptions. Laboratory findings revealed a leucocytosis (14,830/microliter) and an elevated CRP (21.72 mg/dl). The chest radiograph and computed tomography revealed a fluid level in preexisting bullae and a consolidation shadow with multiple cavities in the right upper lobe and nodular shadow with cavity in the left lower lobe. P. aeruginosa strain was isolated from the bronchial lavage and pustule. Blood cultures were negative. Skin biopsy specimens showed histologically a dense infiltrate of neutrophils in the horny cell layer. He was diagnosed as Pseudomonas aeruginosa pneumonia complicated with multiple pustular skin lesions. He was treated with antimicrobial agents for 24 days and his clinical condition improved.
