Introduction: Frantz Tumor is a rare neoplasm, which represents 0.2-2.7% of pancreatic cancers. The majority of patients show minor symptoms or none at all and the diagnosis is usually incidental. We present a case of a young woman with this condition who suffered a blunt abdominal trauma and evolved with hemoperitoneum, undergoing treatment in two steps. Case report: A 13 years old female patient was elbowed in the abdomen, evolving with severe abdominal pain. She had normal vital signs and moderate pain in the mesogastric region, without peritonitis. Laboratory tests showed hemoglobin of 9.3 g/dl. CT Scan: Pancreatic tail showing heterogeneous nodular formation. The aspect was more suggestive of hematoma (volume of 150 mL). Moderate amount of hematic free fluid in the abdominal cavity. We opted for conservative conduct and clinical observation with favorable evolution. New CT Scan after two months: Solid-cystic mass in the tail of the pancreas, approximately 6.0 cm in its longest axis with reduction in the blood component of the pancreatic lesion. The image suggested a pseudopapillary tumor (Frantz tumor). Laparoscopic surgery was performed. The patient had no complications in the postoperative evolution and did not show signs of disease recurrence after two months of follow-up. Conclusion: There are few cases of Frantz tumor described in the literature in children and adolescents diagnosed after abdominal trauma and treated by laparoscopic surgery. This pathology must be among the differential diagnoses for pancreatic neoplasm, especially in young women. Treatment by laparoscopic surgery should be considered.
