Microcystic Serous Cystadenoma of Pancreas Presenting With Chronic Diarrhea

Pancreatic cystic neoplasms are increasingly being recognized due to widespread use of advanced imaging techniques. The prevalence of pancreatic cystic lesions is estimated to be between 2.6% - 19.6%. Serous Cystic Neoplasms account for nearly 16% of surgically resected pancreatic cystic neoplasms. They commonly occur in females between 5th and 6th decade of life. These tumours are essentially benign and asymptomatic unless they attain a large size. Majority of them occur in the body and tail of pancreas. Malignant transformation is reported in 1%-3% of cases. Surgical excision is the treatment of choice. Thus, it is important to accurately diagnose this lesion to avoid unnecessary intervention in the form of chemotherapy or uncalled for surgical resection. We report a rare case of a 65 year old male who presented with a history of intermittent diarrhea.
