  Propionibacterium acnes (P. acnes) have been reported to have an etiologic link with sarcoidosis. A 45-year-old Japanese woman complaining of cough for 1 month presented to our hospital. Chest computed tomography showed an irregular nodular shadow in the right upper pulmonary lobe, a finding suggestive of either pulmonary sarcoidosis or tuberculosis. Biopsy specimens from the pulmonary shadow showed necrotizing granulomas, and there were no other findings from the initial laboratory examinations that could provide a definitive diagnosis. However, immunohistochemical staining using a P. acnes-specific monoclonal antibody revealed small round bodies within the granulomas. Based on these results, we diagnosed the patient clinically with sarcoidosis, and orally inhaled ciclesonide was administered. At a 7-month follow up, the patient had improved clinical.. Read More»
