This case report details a rare instance of a mobile, floating gallbladder in an elderly woman that was incidentally found to harbor double gallbladder cancers. Chronic inflammation leading to gallbladder hydrops may have contributed to cancer development.

Area of Science:

Gastroenterology
Surgical Pathology
Oncology

Background:

Floating gallbladder is a rare congenital anomaly where the gallbladder is suspended by a long mesentery, increasing its mobility.
Gallbladder cancer is uncommon, and double cancers (two distinct tumors) are exceptionally rare.

Observation:

A 79-year-old woman presented with a mobile abdominal cystic mass, later identified as a floating gallbladder.
The gallbladder exhibited an elongated, obstructed cystic duct with a long mesentery.
Histopathological examination revealed two distinct gallbladder cancers.

Findings:

The cystic duct obstruction was attributed to chronic inflammation, causing gallbladder hydrops.
This hydrops is suspected to have played a role in the carcinogenesis process.

This represents the first reported case of a floating gallbladder associated with double gallbladder cancers.

Implications:

Highlights the importance of thorough histopathological examination in cases of gallbladder anomalies.
Suggests a potential link between chronic inflammation, gallbladder hydrops, and the development of multiple gallbladder cancers.
Contributes to the understanding of rare gallbladder pathologies and their association with malignancy.
