Gallbladder

Gallbladder

The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins the common...

Cholecystitis

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Area of Science:

Oncology
Surgical Pathology

Background:

Carcinosarcoma of the gallbladder (CSGB) is a rare malignancy with unknown pathogenesis.
CSGB typically presents at advanced stages, leading to uncommon curative resections and poor survival rates.

Observation:

A 77-year-old woman presented with right upper quadrant pain, initially diagnosed as gallbladder cancer.
A curative radical cholecystectomy was performed, but pathology revealed a biphasic tumor: squamous cell carcinoma and spindle cell sarcoma.

Findings:

The resected CSGB extended to the perimuscular connective tissue.
Metastasis to one lymph node was identified in the surgical specimen.

Implications:

Despite curative resection, the prognosis for CSGB remains poor.
Enhanced surgical strategies and outcomes are crucial for improving patient survival in CSGB cases.
