Abstract
|
|
|
|
Adenomyomatous hyperplasia (AMH) of the gallbladder commonly accompanies chronic cholecystitis and may be classified into three types according to the gross features: segmental, localized (fundal), and diffuse types. In situ or invasive carcinomas arising from and confined to AMH are rarely observed, especially of the segmental type. Intracystic papillary neoplasm (IPN) is one of the precancerous lesions of the gallbladder. IPN usually grows into the lumen and produces a polypoid or papillary mass. Here, we report an extremely rare case of IPN arising from and limited to a localized AMH incidentally detected in a brain-dead 68-year-old female patient during organ harvesting.
