[Diffuse peritoneal carcinosis of pseudo-papillary and solid tumor of the pancreas. Role of abdominal injury].

We report the case of a young girl with diffuse peritoneal carcinomatosis due to pseudopapillary and solid tumor of the pancreas. Fourteen months before the diagnosis and treatment of the tumor, an abdominal trauma occurred. Initial treatment was tumor and visible peritoneal carcinomatosis resection. Eight months later, relapse of peritoneal carcinomatosis occurred and the patient was reoperated. All macroscopic lesions were removed. Thirty-seven months after first laparotomy, the patient was well but abdominal ultrasound led to suspicion of hepatic metastasis. Among 17 published cases of metastatic pseudopapillary and solid tumor of the pancreas (including 6 cases with peritoneal carcinomatosis), trauma was described in 11 cases (including 3 cases with peritoneal carcinomatosis). Pseudopapillary and solid tumor of the pancreas may spread outside the pancreas, particularly in peritoneal cavity. Metastatic spread may be promoted by trauma, including tumor biopsies which should never be performed.
