Sarcoidosis misdiagnosed as malignant tumors: a case report

[摘要] BackgroundSarcoidosis is a rare condition that is often misdiagnosed as malignant tumors due to the similar clinical manifestations and imaging findings.Case PresentationWe encountered a 56-year-old Chinese woman who had a chief complaint of a persistent cough. The chest computer tomography (CT) revealed mediastinal and bilateral hilar lymph node enlargement, and positron emission tomography-computer tomography (PET-CT) revealed abnormal fluorodeoxyglucose (FDG) uptake in the lymph nodes of the chest and abdomen. To further clarify the diagnosis, a lymph node sampling was performed by video-assisted thoracoscopic surgery (VATS) and the histopathologic diagnosis of sarcoidosis was confirmed.ConclusionsVATS could be an effective and minimally invasive diagnostic method to discriminate pulmonary sarcoidosis with other malignant tumors.
