[Acute diffuse peritonitis of a rare cause]
Abstract:
The authors report a rare case of acute onset of non-Hodgkin lymphoma with diffuse peritonitis due to bowel perforation of secondary jejunal involvement. The admission diagnosis in the 18-years-old male with acute abdominal pain for 4 days, guarding on physical examination and pneumoperitoneum on abdominal ultrasonography was peptic ulcus perforation. The palpable splenomegaly and cervical lymph nodes on ultrasonography examination might have raised suspicion of lymphoma. Surgical exploration revealed the peritonitis origin--jejunal perforation, proximal to a stenosing tumor, a gastric tumor and confirmed the splenomegaly. Small bowel resection--end to end anastomosis--and gastric tumor biopsies were performed. The pathological diagnosis was diffuse large B-cell non-Hodgkin lymphoma. Some therapeutic considerations on digestive tract secondary lymphoma are made.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
