Insights

Extramedullary plasmacytoma, a rare plasma cell tumor, can occur in the gallbladder. This case highlights gallbladder extramedullary plasmacytoma without multiple myeloma, presenting with gastrointestinal symptoms.

Area of Science:

  • Oncology
  • Gastroenterology
  • Pathology

Background:

  • Extramedullary plasmacytoma (EMP) is a rare plasma cell neoplasm.
  • While typically found in the upper aerodigestive tract, EMP can occur elsewhere in the digestive system.
  • Gallbladder involvement by EMP is exceptionally uncommon.

Conclusions:

  • Extramedullary plasmacytoma is a rare differential diagnosis for gallbladder masses.
  • Gallbladder EMP can present with gastrointestinal symptoms mimicking malignancy.
  • Surgical resection and pathological analysis are crucial for accurate diagnosis.

Gallbladder01:17

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...
Cholecystitis01:20

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...
