Abstract
Background. Acute sarcoidosis is a rare disease in Japan. We report a case of acute sarcoidosis diagnosed by EBUS-TBNA (endobronchial ultrasound guided transbronchial needle aspiration). Case. A 55-year-old woman who had a history of bilateral mammoplasty at the age of 23 developed fever and bilateral knee joint pain in February 20XX. Pointed out of bilateral hilar lymphadenopathy on chest X-ray, she was referred to our hospital. Chest enhanced computed tomography revealed mediastinal and bilateral hilar lymphadenopathy, and gallium scintigraphy showed multiple accumulations on major joints, mediastinal and bilateral hilar lymph node. A hilar lymph node specimen obtained by EBUS-TBNA revealed non-caseating epithelioid cell granulomas typical of sarcoidosis histologically. There are few reports of acute sarcoidosis with joint involvement in Japan. Moreover the association between sarcoidosis and mammoplasty was indicated. Conclusion. We report a case of acute sarcoidosis with fever and joint involvement after bilateral mammoplasty diagnosed by EBUS-TBNA.
