The Frantz tumor (solid pseudopapillary neoplasm – SPN) is a rare, usually benign tumor of unclear etiology having a predilection for young women. This usually asymptomatic tumor may, however, be a cause of abdominal pain or discomfort. In our case, the mentioned tumor was a cause of abdominal pain in a 14-year-old, a so far healthy patient. Abdominal imaging – USG and computed tomography scan (CT) were performed showing a large mass in the left epi- and mesogastrium with primary location probably in the pancreas. A laparoscopic biopsy was performed and confirmed the initial diagnosis. A tumor along with the pancreatic tail were removed by laparotomy without complications. The case we described shows that a solid pseudopapillary neoplasm can be a rare cause of abdominal pain in pediatric patients.
