Abstract:
A 72-year-old woman had severe watery diarrhea and weight loss. Computed tomography demonstrated a 55mm tumor in pancreatic tail with enlargement of para-aortic lymph nodes. There was no apparent liver metastasis. Endoscopic ultrasound demonstrated a well-circumscribed heterogenous tumor, which was diagnosed neuroendocrine tumor by endoscopic ultrasound-guided fine needle aspiration biopsy. For suspected VIPoma with para-aortic lymph node involvement, distal pancreatectomy and para-aortic lymphadenectomy was performed. The tumor was diagnosed as VIPoma by immunohistochemistry. The diarrhea improved after surgery. No evidence of recurrence was detected after a follow-up of 11 months.

Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
