Sarcoidosis misdiagnosed as malignant tumors: a case report
نویسندگان
چکیده
BACKGROUND Sarcoidosis is a rare condition that is often misdiagnosed as malignant tumors due to the similar clinical manifestations and imaging findings. CASE PRESENTATION We 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. CONCLUSIONS VATS could be an effective and minimally invasive diagnostic method to discriminate pulmonary sarcoidosis with other malignant tumors.
