Simultaneous serous cystadenoma of the pancreas and mucinous cystadenoma of the appendix.
BACKGROUND
Serous cystadenoma of the pancreas and mucinous tumors of the vermiform appendix are rare. To our knowledge, the simultaneous occurrence of these two tumors has not been reported.


METHODS
Here, we report an adult female who presented with signs and symptoms of appendicitis. A preoperative CT scan confirmed the findings of appendicitis and also showed an incidental large mass in the head of the pancreas. The patient underwent uneventful appendectomy. Her pathology revealed an acutely inflamed appendix with a benign mucinous cystadenoma at the tip. Several months after her recovery, a Whipple procedure was performed. Pathologic examination showed a 5x5 cm serous cystadenoma of the head of the pancreas without evidence of malignancy. Two years later, the patient is alive and well without evidence of tumor recurrence.


CONCLUSIONS
Cystadenomas of the pancreas and appendix are unusual and their simultaneous occurrence is a rare event.
