Neuroendocrine tumor of the minor duodenal papilla with lymph node metastasis: a case report and literature review.

Whether pancreatoduodenectomy or papillary resection should be performed to achieve curative treatment for neuroendocrine tumors of the minor duodenal papilla with a diameter of ≤2 cm is controversial. We report a 35-year-old male patient with a rare case of a neuroendocrine tumor of the minor duodenal papilla. The patient was referred to our hospital from a different clinic for dilatation of his minor duodenal papilla.

Lesser omental panniculitis: a possible cause of acute abdomen.

We encountered a case of panniculitis of the lesser omentum in 2018 after a long time since our first case report in 2007. We reviewed previously reported three cases of lesser omental panniculitis including our first case to investigate its clinical characteristics. Total four cases were relatively young with mean age of 30, and had common chief complaint of considerable epigastric pain and tenderness.

Submucosal fat accumulation in human colorectal tissue and its association with abdominal obesity and insulin resistance.

Background: In addition to visceral fat, peripheral ectopic fat accumulation is suggested to play a role in the pathophysiology of metabolic syndrome, which is known to be associated with not only cardiovascular diseases and type 2 diabetes mellitus but also colorectal cancer.

Objective: This study aims to clarify whether there is ectopic fat accumulation in human colorectal tissue in association with metabolic syndrome or its components such as abdominal obesity and insulin resistance.

Methods: Lipid contents of colorectal tissue were measured in 27 patients with colorectal polyp excised endoscopically.

A case of pancreatic acinar cell carcinoma metastatic to skin.

Computed tomography showed a pancreatic mass with hepatic tumors and enlarged lymph nodes besides ring-enhanced subcutaneous nodules. Magnetic resonance diffusionweighted imaging detected the presence of lesions in other organs.
