Incidental signet ring cell carcinoma of the gallbladder in routine histopathology

Cholecystectomy is a common surgical procedure for various indications. Preoperative imaging is the main stay in the management of the patients. Routine and/or selective histopathological examination of the cholecystectomy materials have been discussed previously. However, incidental findings may be only observed with routine histopathological examination. Here, we report an incidental gallbladder signet cell carcinoma in a 66 years old patient. This case underlines the importance of routine histopathological examination after cholecystectomy.
