Metastatic Cecal Adenocarcinoma to the Gallbladder Presenting with Acute Cholecystitis.

Colorectal cancer (CRC) is one of the most common cancers and the second highest cause of cancer-related deaths (Jemal et al., 2011). Common presentations of CRC include alterations in bowel habit, weight loss, and lower gastrointestinal bleeding. We report a case of a 74-year-old male who presented with fever and right upper quadrant pain, with positive Murphy's sign on examination. The case was initially managed with a routine cholecystectomy. Histological examination revealed a moderately differentiated adenocarcinoma with a superimposed histologically proven acute acalculous cholecystitis. CT scan done postsurgery showed a cecal mass with retroperitoneal lymphadenopathy. Biopsy result of cecal mass was remarkable for colon adenocarcinoma. We are not aware of any similar prior cases reported in English literature.
