title: [An unusual case of pulmonary granulomatous lesion in an immunocompetent patient: infection caused by Pasteurella multocida].
abstract: We report a case of lung infection caused by Pasteurella multocida in an immunocompetent patient. Diagnosis was made both on histological analysis of a lung wedge resection, showing pyoepithelioid granulomas, and on bacteriological cultures from lung tissue. Histological diagnosis of pulmonary pasteurellosis is difficult, and other etiological causes of pyoepithelioid granulomas of the lung have to be discussed. Pulmonary pasteurellosis is particularly severe in immunocompromised patients, and should be systematically suspected in patients exposed to pets, eventhough a percutaneous exposure is not usually found for these patients.
