  Fig. 1. Brunner's gland hamartoma or adenoma (hematoxylin & eosin stain, ×200). (A) Brunner's gland hamartoma is composed of a dilated cyst. (B) Hyperplasia of Brunner’s glands and fibrous stroma.

• 

  Fig. 2. (A) Endoscopy reveals a pedunculated polypoid mass in the duodenal bulb. (B) Endoscopic ultrasound reveals a heterogeneous appearance with an anechoic lesion representing cysts (red arrow). (C) On computed tomography, a round mass with a well-demarcated cystic lesion in the duodenal bulb is shown (red arrow). (D) Histological examination reveals the proliferation of Brunner's glands and fibrous stroma with several dilated cysts (blue arrow, hematoxylin & eosin stain, ×10).

• 

  Fig. 3. (A) Endoscopy reveals a round sessile polypoid mass in the second portion of the duodenum (red arrow). (B) On endoscopic ultrasond, a heterogeneous hyperechoic appearance without anechoic lesions is shown (red arrow). (C) Histological examination reveals dense Brunner's gland proliferation without definite cystic lesions (hematoxylin & eosin stain, ×10)

• 

  Fig. 4. (A) Endoscopy reveals a round sessile polypoid mass in the duodenal bulb. (B) Endoscopic ultrasound reveals a heterogeneous appearance, with tiny anechoic lesions representing cysts (red arrow). (C) On computed tomography, a homogeneous round mass in the duodenal bulb is shown (red arrow). (D) Histological examination reveals the proliferation of Brunner's glands and fibrous stroma without cystic lesions (hematoxylin & eosin stain, ×10).
