Concomitant Carcinoma of the Gallbladder and Incidental Gallstones, and Concurrent Gallbladder Cyst: A Case Report

Abstract

Introduction: Gallbladder carcinoma is a malignant epithelial neoplasm of the gallbladder. The tumor is clinically
aggressive, with an overall 5-year survival rate of < 10%. Cholelithiasis is a known and established risk factor. Up to
50% of gallbladder tumors are detected incidentally in routine cholecystectomy specimens due to the absence of gross
abnormalities. Gallbladder carcinoma has several unusual presentations, one of which is an incidental pseudocyst with
cholelithiasis and perforation. This unusual occurrence makes the index case unique.
Case presentation: We report a case of gallbladder cancer diagnosed by an emergency cholecystectomy, performed
for acute cholecystitis caused by a pseudocyst. The patient underwent chemotherapy, and currently, 12 months have
passed. The patient is doing well, without signs of recurrence or metastasis.
Conclusions: Systematic sampling of cystectomy specimens is therefore crucial to detecting incidental gallbladder
adenocarcinomas.
