Sepsis due to Erysipelothrix rhusiopathiae in a patient with chronic lymphocytic leukemia associated with bronchopneumonia due to Pseudomonas aeruginosa and Escherichia coli: A case report

INTRODUCTION The present report describes a case of sepsis due to Erysipelothrix rhusiopathiae in a patient with B-cell chronic lymphocytic leukemia with no animal exposure, associated with concomitant bronchopneumonia due to Pseudomonas aeruginosa and Escherichia coli. CASE PRESENTATION A 54-year-old Caucasian man presented to an emergency room with a three-day history of chest pain, fever, cough with purulent sputum, chills and dyspnea. The patient had associated erythematous papules on the chest and enlarged axillary, submandibular, pectoral and supraclavicular lymph nodes, which regressed under treatment with penicillin. The patient was found to have sepsis without endocarditis caused by E rhusiopathiae, associated with bronchopneumonia that was induced by a double Gram-negative infection. CONCLUSIONS The underlying-B cell chronic lymphocytic leukemia may have favoured the development of bacteremia due to E rhusiopathiae, which occurred subsequent to glossitis in an immunocompromised host being treated with methylprednisolone and cladribine.
