Introduction: Gall bladder carcinoma is the most common biliary tract malignancy worldwide.1Aggressivebiological nature of the tumor results in rapid spread of the tumor to adjoining vital structures since theGB is located in an anatomically busy area.1The tumor is thus, often unresectable at presentation.In thisretrospective study we aimed to establish the overall rate of unsuspected gallbladder carcinoma in allcholecystectomy specimens in a tertiary care hospital in the eastern part of India.Material and Method: In our study we have reviewed the clinical records of consecutive 731Cholecystectomyspecimens during the last 5 Years (2014May-2019April) .A uniform procedure of history taking,physicalexamination, investigation and treatment adopted for all the patients.Diagnosis of Incidental gall bladdercarcinoma was confirmed on microscopic examination.Results: During the last 5 years, 731 cholecystectomies were performed in this tertiary care hospital. Outof them 65.43% was from female population whereas 34.57% were from male. Median age of the patientpopulation is around 55± 9.34 years.Most of the approaches were laparotomy.Evaluation of the all pathologicspecimen revealed 74 cases of gall bladder carcinoma which comprises 10.12% of all the cholecystectomiesdone in that aforesaid period.Conclusions: The findings of Incidental gall bladder carcinoma is a clinical problematic scenario whichoften misses the eye of a radiologist and comes as a histopathological surprise. Microscopical examinationof all cholecystectomy specimen should be done because it is not only the gold standard diagnostic methodbut also reveals the occult malignancy at the earliest.
