  Fig. 1. (A) Contrast-enhanced computed tomography demonstrates a 2.6-cm, round, enhancing mass in the pancreatic tail. (B) Endoscopic ultrasonography shows a 1.9 cm×2.3 cm round hypoechoic mass with well-defined margin at pancreatic tail. (C) Contrast-enhanced endoscopic ultrasonography shows homogenous enhancement of the mass. (D) Endoscopic ultrasound-guided fine needle aspiration is performed. (E) Cytology shows no malignant cells.

  Fig. 2. (A) Gross appearance of the resected specimen reveals a 2.3 cm×1.5 cm well-demarcated, dark brown mass in the pancreatic tail. (B) Microscopic examination reveals that the mass is surrounded by normal pancreatic tissue and composed of follicles and germinal centers (hematoxylin and eosin stain, ×20).
