Sarcoidosis is a multi-organ disease with various clinical manifestations. The lung is the most common site of manifestation; however, unusual findings may delay the correct diagnosis of sarcoidosis. Here we report a case of 32-year-old man with 4-month history of neck mass. Radiological findings revealed multiple pulmonary parenchymal nodules, with initial biopsy results of his neck lymph node showing chronic granuloma with focal necrosis. The patient was treated with anti-tuberculosis medications, but the size of the nodules did not change. Biopsy was performed from one of his pulmonary nodules, which revealed chronic granuloma without necrosis. Therefore, the patient was diagnosed with sarcoidosis. We present a case of sarcoidosis with multiple lung parenchymal nodules that is uncommon in Korea, with an aim to alert physicians of such unusual presentations.

Gastric sarcoidosis is a rare disease accounting for 0.1~0.9% of all sarcoidosis cases. It presents either as a systemic disease or as an isolated finding. Diagnosis is established with biopsy of a lesion. It is important to distinguish between sarcoidosis and a sarcoid-like reaction, which can be caused by Crohn's disease, foreign body reaction, fungal infection, tuberculosis, or malignancy. We report a 60-year-old woman with both gastric and pulmonary sarcoidosis.
