INTRODUCTION Porcelain gallbladder is a very rare entity that consists of a calcification of the gallbladder wall, and is associated with carcinoma in 12.5-62% of patients, although recent studies suggest weaker association. CASE REPORT We describe an 80-year-old woman who presented with colicky abdominal pain in the right upper quadrant, radiating to the back and associated with vomiting. Ph...

OBJECTIVE Estrogen interacts with a membrane receptor, G protein-coupled estrogen receptor (GPER). It was reported that 17β-estradiol was able to inhibit contraction of the human colon and cause relaxation of the guinea pig gallbladder, however, the involvement of GPER was not clarified. The aim of the present study was to investigate the effect of estrogen on human gallbladder motility and the...

BACKGROUND Incidental gallbladder cancer is found in upto 1% of cholecystectomy specimens for gallstone disease. Currently, in our institution, all gallbladder specimens are sent for routine histopathology, to rule out incidental gallbladder carcinoma. This study was aimed at assessing the need for routine histopathology of gallbladder specimens after cholecystectomy for gallstone disease. ME...

The effect of vagotomy on gallbladder function was investigated in a clinical and experimental study. In the clinical study both the size of the gallbladder and its capacity to respond to cholecystokinin were evaluated radiologically before and after vagotomy. In studies in the rabbit, both the immediate effect of vagotomy on the gallbladder and the effect of varying doses of cholecystokinin on...

INTRODUCTION Gallbladder torsion is mainly associated with a floating gallbladder. From an anatomical perspective, laparoscopic cholecystectomy is a more optimal treatment than open cholecystectomy. PRESENTATION OF CASE An 84-year-old woman visited the Onomichi General Hospital because of progressive pain in the right upper quadrant of her abdomen. Physical examination revealed a positive Mur...

Gallbladder carcinosarcoma is one of the rarest subsets of gallbladder malignancies. The first case of carcinosarcoma of the gallbladder was reported in 1907. To date, <100 cases have been reported in the English literature. The present study reports a case of gallbladder carcinosarcoma accompanied with tumor thrombi, presenting as a soft tissue mass in the common bile duct and resulting in the...

Porcelain gallbladder or calcified gallbladder is a rare entity and is considered as the end stage of chronic cholecystitis. This disease is rarely diagnosed preoperatively and usually mimics carcinoma gallbladder. Hereby, we present a rare and interesting case of porcelain gallbladder that was diagnosed preoperatively and managed by cholecystectomy. How to cite this article: Goel A, Agarwal A,...

Gallbladder (GB) carcinomas are adenocarcinomas (AC) in the majority of cases. Adenosquamous carcinoma (ASC) and pure squamous cell carcinoma (SCC) of the gallbladder are rarely encountered and comprise 1-3% of gallbladder cancer cases.  Pure squamous cell carcinoma of the gallbladder is rarer with less than 1% of the incidence. Most of the published literature is based on case reports and case...

Mucosa-associated lymphoid tissue (MALT) lymphoma is rarely observed in the gallbladder, and its diagnosis before surgery is difficult. This report describes a case of primary MALT lymphoma of the gallbladder in an 80-year-old man. Imaging studies revealed a protruding lesion on the inside of the gallbladder, which led us to diagnose gallbladder carcinoma prior to the patient undergoing extende...
