Abstract:
Metastatic involvement of the gallbladder is uncommon. We report a case of an 84-year-old male who presented with acute cholecystitis secondary to metastatic urothelial carcinoma (UC). An 84-year-old man presented with right upper quadrant pain and a positive Murphy's sign on the background of known metastatic UC. He was diagnosed with acute cholecystitis and underwent laparoscopic cholecystectomy. His postoperative period was complicated by a cardiac event, and he died 2 days later. Histology of the gallbladder revealed extensive infiltration by nested malignant epithelioid proliferation, consistent with UC. This case demonstrates that although uncommon, UC may metastasize to unusual sites, including the gallbladder. This serves as a reminder for surgeons to consider metastatic disease as a cause for acute cholecystitis.

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
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.
The causes of acute pancreatitis include:
Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Acute Respiratory Failure-V
Ensure that patients are monitored continuously for their response to therapy, including changes in...
