Background: Pancreatic cystic lesions (PCL) are identified in 1 % of patients who undergo abdominal computed tomography scans, because it is difficult to discriminate clinically between benign and malignant PCL. The PCL must be distinguished from inflammatory pseudocysts, which can have a similar radiographic appearance. The aim of this study was to review the incidence of PCL during 10 years., Methods: Nineteen consecutive patients who underwent surgical resection of a cystic lesion of the pancreas during a 10-year period were reviewed., Results: From 1998, 434 patients underwent to pancreatic surgery, 103 (25.75%) resulted with neoplasm of the pancreas and a PCL was diagnosed in 19 of them (18.44%). They were more common in women (n=15, 79%). The pathologic diagnosis was mucinous cystadenoma (n=6, 31.5%) followed by serous cystadenoma and solid cystic papilar tumor (n=4, 21%). Mucinous cystadenocarcinoma was diagnosed in a 77 year-old man and a serous cystadenocarcinoma was diagnosed in a 53 years-old woman; cystic degeneration of two insulinomas were diagnosed in a 71 year-old woman and a 32 year-old man (5.26%)., Conclusions: PCLs represent a spectrum of associated diseases. The incidence of serous cystadenoma is lower in our experience.

Objective: The objective of this report is to describe the existence of a rare tumor that must be taken into consideration when studying the diagnosis of pancreatic tumors., Case Report: A 20-year-old female with abdominal pain as an only manifestation was seen. The diagnosis of a pancreatic head and body tumor was made. During surgery, we found a tumor in the head and body of the pancreas that measured approximately 10 x 7 cm; histopathologic study revealed a solid and cystic papillary epithelial neoplasm of the pancreas., Discussion: Frantz-Gruber tumor is a rare pancreatic tumor suspected during the evaluation of a young female with abdominal pain and confirmed during surgery. It is important to consider the existence of this tumor in the evaluation of patients with these characteristics; even if the tumor's biological behavior is benign Frantz-Gruber tumor is considered a low-grade malignant tumor
