Pancreatoblastoma is a rare primary pancreatic neoplasm of children that may arise in any portion of the pancreas. We report a case of a 3-yr-old boy who presented to with abdominal pain our hospital and a progressive bulge in his right abdomen. Biochemical evaluation and serum levels of tumoral markers were within reference limits. On the computed tomography, two tumors were found. One located in the head of the pancreas; however, a laparotomy revealed that the head of pancreas was compressed but normal. The other was in the left abdomen near the spleen and the tail of the pancreas. The diagnosis of two synchronous pancreatoblastoma originating from the omentum was confirmed by pathology. Therefore, a pancreatoblastoma should be considered when a large well-defined, lobulated, and heterogeneous mass is identified in the pancreas of children. In addition, an ectopic pancreatoblastoma should be considered when identified within or near the ectopic pancreatic tissue.

INTRODUCTIONPatients with peritoneal metastases (PM) from hepatocellular carcinoma (HCC) often experience a rapid demise even after a complete removal of intrahepatic tumour. Localised PM may now be adequately controlled and managed with cytoreductive surgery (CRS).

TREATMENTThree patients underwent CRS for HCC PM.

OUTCOMEThe first patient survived 21 months from the time of CRS and is alive with the disease. The second patient died 4 months after CRS. The third patient survived 10 months since CRS and is also alive with the disease. Collectively, the survival of 24 patients with HCC PM extracted through a collective literature review who were treated with cytoreductive surgery had 1- and 2-year survival percentages of 83% and 71%, respectively.

CONCLUSIONCareful selection of patients with localised disease to the peritoneal cavity for CRS, taking into consideration the performance status, liver function and tumour biology may lead to a successful outcome in patients with HCC PM.

OBJECTIVEExtraovarian peritoneal serous papillary carcinoma (EPSPC) is both histologically and clinically similar to stage III-IV ovarian papillary serous carcinoma (OPSC). The purpose of this study is to investigate the clinical findings, treatment, and outcome of EPSPC patients compared with stage III-IV OPSC patients.

METHODSThe data of 12 EPSPC patients and 45 stage III-IV OPSC patients were retrospectively reviewed, comparing the characteristics on clinical presentation and treatment, sensitivity to first-line chemotherapy agents and survival.

RESULTSBy analysis of patients' characteristics, presenting signs and symptoms, type and extent of surgery, tumor response to first-line chemotherapy, recurrence-free interval, recurrence site and serum CA-125 levels, no significant difference was observed between the EPSPC patients and stage III-IV OPSC controls. The prevailing presenting symptoms were abdominal mass and ascites. The mainstay of treatment was debulking surgery followed by adjuvant platinum-based chemotherapy. The complete clinical response of stage III-IV OPSC was 91.8% compared with 25.0% for women with EPSPC (P < 0.01).

CONCLUSIONThe clinical and surgical characteristics of EPSPC are similar to those of stage III-IV OPSC. When the same treatment strategy is applied, similar response and survival are expected in either condition.

OBJECTIVE: This study was undertaken for the purpose of describing the CT features of intra-abdominal extra-hepatic metastases from gastrointestinal stromal tumors in patients who were treated with imatinib. MATERIALS AND METHODS: Eleven patients with intra-abdominal extra-hepatic metastases from gastrointestinal stromal tumors, who were treated with imatinib between May 2001 and December 2003, were included in this study. The clinical findings and CT scans were retrospectively reviewed. The metastatic lesions were assessed according to the location, size (greatest diameter), attenuation, and the enhancing pattern before and after imatinib treatment. RESULTS: Prior to the treatment, the sizes and attenuation values of the metastatic lesions ranged from 5 to 20 cm and from 63 to 131 H, respectively. The metastatic lesions showed a heterogeneous enhancement pattern on the contrast-enhanced CT scans. After the treatment, the metastatic lesions became smaller in all 11 patients, and the corresponding attenuation value ranged from 15 to 51 H. The metastatic lesions became homogeneous and cystic in appearance on the follow-up CT scans, mimicking ascites. CONCLUSION: Intra-abdominal extra-hepatic metastases of patients with gastrointestinal stromal tumors treated with imatinib may appear as well-circumscribed cystic lesions on contrast-enhanced CT. These metastases are likely to become smaller and resemble ascites, but may persist indefinitely on the follow-up CT.
