Abstract
We herein report a 52-year-old man with multiple hypoechoic lesions in the body and tail of the pancreas detected during a screening ultrasound. Computed tomography (CT) showed no lesions other than those in the pancreas and peripheral lymph nodes. Contrast-enhanced CT identified hypovascular tumors in the pancreas. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) demonstrated partial fibrosis and noncaseating granulomas with Langhans giant cells. To our knowledge, this is the first report of isolated pancreatic sarcoidosis diagnosed by EUS-FNA. Although pancreatic sarcoidosis is very rare, clinicians should be aware of this possibility in patients presenting with multiple hypovascular pancreatic tumors.
