PURPOSE: Primary pancreatic carcinoma and pancreatic metastases are rare in the pediatric population. Pancreatoblastoma is the most common pancreatic malignant tumor in young children and solid-pseudopapillary tumor in teenagers. Pancreatic adenocarcinoma is extremely rare under the age of 40 and is usually associated with underlying genetic abnormalities. Secondary malignancies of the pancreas occur more frequently than primary pancreatic malignancies in children and are most commonly seen with non-Hodgkin lymphomas (NHL) and mesenchymal sarcomas...

During next generation sequencing (NGS) analysis, many missense mutations were found in a well-known oncogene, many of which were variant of uncertain significance mutations. We recently treated an adult patient with pancreatoblastoma by chemotherapy. Using an NGS cancer panel, we found a previously unreported missense mutation in the 1835 codon of the adenomatous polyposis coli ( APC ) gene. We also found a heterogeneous mutation in the 1835 codon of the APC gene in the patient's germline by Sanger sequencing...

The authors describe a 31-year-old man admitted due to progressive weight loss, diarrhea and massive hepatomegaly. Laboratory data showed anemia (haemoglobin 11.7 g/dl), abnormal liver tests (total bilirubin 1.4 g/dl, aspartate aminotransferase 70 U/l, alanine aminotransferase 37 U/l and alkaline phosphatase 520 U/l). Abdominal ultrasound (US) displayed a large heterogeneous liver with a segment IV 25 mm nodule. Magnetic resonance revealed a 4 cm pancreatic tail mass and several liver nodules consistent with metastasis...

Pancreatic carcinomas with acinar differentiation are rare, accounting for 1%-2% of adult pancreatic tumors; they include pancreatic acinar cell carcinoma (PACC), pancreatoblastoma, and carcinomas of mixed differentiation. Patients with PACC have a prognosis better than pancreatic ductal adenocarcinomas but worse than pancreatic neuroendocrine tumors. Reports of overall survival range from 18 to 47 mo. A literature review on PACCs included comprehensive genomic profiling and whole exome sequencing on a series of more than 70 patients as well as other diagnostic studies including immunohistochemistry...

PURPOSE: While pancreaticoduodenectomy (PD) has been extensively studied in adults, there are few data pertaining specifically to pediatric patients. We retrospectively analyzed PD-associated morbidity and mortality in pediatric patients. METHODS: Our analytic cohort included all consecutive patients ≤18years of age treated at our institution from 1993 to 2015 who underwent PD. Patient data (demographics, disease characteristics, surgical and adjuvant treatment, length of hospital stay, and postoperative course) were extracted from the medical records...

Most cases of pancreatoblastoma, a rare malignant epithelial tumor of the pancreas, are seen in the pediatric population. The rarity of pancreatoblastoma, the similar radiologic findings to those seen in other pancreatic lesions, and its histopathologic heterogeneity, make its preoperative diagnosis in adults a real challenge. We report ultrasound, computed tomography and magnetic resonance imaging correlative findings of a histologically proven pancreatoblastoma in a 37-year-old woman. Pancreatoblastoma should be considered in the differential diagnosis of a pancreatic mass presenting uncommon imaging features...

Pancreatoblastoma (PB) is a rare malignant neoplasm of the pancreas with unknown etiology. It occurs mostly in the pediatric population with very rare documented cases in adults. This is a review of the case reports of the adult pancreatoblastoma in the literature. A total of 35 cases were identified and reviewed with the mean age of 41 years (range, 18-78 years) and the male sex accounted for 51.4% of the cases. Adult Pancreatoblastoma seem to have a predilection for the head of the pancreas which accounted for approximately 49% of the cases reviewed with an average size of 8 cm (range, 1...

The present study describes the case of a 24-year-old patient who presented with obstructive jaundice and weight loss, and was diagnosed with pancreatoblastoma (PB). Abdominal imaging studies revealed a heterogenous lesion of the pancreatic head with dilatation of the common bile duct. The patient underwent pancreaticoduodenectomy, however, three months after surgery multiple liver and bone metastases were identified on follow-up computed tomography scans. Despite treatment with four cycles of systemic chemotherapy and five courses of radiofrequency ablation, the patient succumbed due to tumour dissemination 13 months after initial diagnosis...

Pancreatoblastoma is a malignant pancreatic tumor that rarely occurs in adults. We report a case of an adult female with pancreatoblastoma. A mass was detected in the pancreatic head using computed tomography and ultrasonography. The clinical diagnosis was a solid-pseudopapillary neoplasm of the pancreas. However, after the operation, the final diagnosis was pancreatoblastoma, which showed two lines of differentiation: Acinar differentiation and squamoid corpuscles. The patient is currently in good condition...

Pancreatic neoplasms with acinar differentiation, including acinar cell carcinoma, pancreatoblastoma, and carcinomas with mixed differentiation, are distinctive pancreatic neoplasms with a poor prognosis. These neoplasms are clinically, pathologically, and genetically unique when compared to other more common pancreatic neoplasms. Most occur in adults, although pancreatoblastomas usually affect children under 10 years old. All of these neoplasms exhibit characteristic histologic features including a solid or acinar growth pattern, dense neoplastic cellularity, uniform nuclei with prominent nucleoli, and granular eosinophilic cytoplasm...

Pancreatoblastomas are malignant epithelial neoplasms of the pancreas that are heterogeneous and have variable cellular differentiation, complicating the diagnosis. We report a case of pancreatoblastoma occurring in an adult patient, presenting as a pancreatic head mass with liver metastasis and jaundice. The initial liver biopsy diagnosis was metastatic neuroendocrine carcinoma based on morphology and synaptophysin positivity. At pancreatic resection, the diagnostic features of pancreatoblastoma were recognized...

BACKGROUND: Acinar cell neoplasms of the pancreas are rare but when encountered, the diagnosis is often established based on cytology specimens. Diagnostic accuracy is important because acinar cell carcinomas are aggressive yet may mimic tumors with different outcomes and management. METHODS: The authors identified all patients with a diagnosis of acinar cell neoplasm in the institutional database; assessed cytomorphology and immunocytochemistry for trypsin, chymotrypsin, synaptophysin, chromogranin A, and MIB-1; and compared all cytology and final histological diagnoses for diagnostic discrepancies...

INTRODUCTION: Pancreatic tumor is a rare condition in children, but reasonably common in adults. Histopathology in children also differs from that in adults, with most cases being pancreatoblastoma, solid pseudopapillary tumor, or pancreatic endocrine tumors. PRESENTATION OF CASE: A 14-month-old boy was noticed abdominal distension and referred to our hospital. Laboratory findings revealed leukocytosis and elevation of serum level of C-reactive protein and pancreatic enzymes...

Ex situ ex vivo liver surgery represents a method to expand the surgical indications to treat otherwise unresectable liver tumors. We report the case of a 38-year old woman with hepatic metastasis from a pancreatoblastoma that was judged to be unresectable due to the involvement of the three hepatic veins. To treat the primary tumor, she underwent a pancreaticoduodenectomy, adjuvant chemotherapy, and thermal ablation of a liver metastasis. After appropriate preoperative study and with the permission of the ethics committee, she underwent ex situ ex vivo liver resection...

CONTEXT: Pancreatoblastoma is a rare neoplasm in adults with a total of only 24 cases that have been reported in the literature. Adult pancreatoblastomas are large tumors and majority are larger than 8 cm at the time of diagnosis. Metastasis is seen in 26% of adults and usually involves the liver and then the lymph nodes. Metastasis is usually observed in cases where the primary tumor measures more than 10 cm. Pancreatoblastoma is named after its resemblance to fetal pancreatic tissue in the seventh week of life...

Pancreatoblastoma is a very rare childhood tumor originating from the epithelial exocrine cells of the pancreas. It is the most common malignant pancreatic tumor in young children and has a mean age of diagnosis of 5 years. It is slow growing and its presentation is varied and often non-specific. Tumors tend to be quite large and appropriate cross sectional imaging is very important to assess for extent, metastatic disease, and resectability. Biopsy for tissue diagnosis is essential. Complete surgical resection is the goal of therapy although many patients are unresectable at initial diagnosis and require neoadjuvant chemotherapy...

AIMS: To determine the maximum tolerated dose, the recommended dose (RD) for phase II studies, dose-limiting toxicities and pharmacokinetics (PK) for plitidepsin administered as a 3-h intravenous infusion every 2weeks (one cycle) to children with refractory or relapsed solid tumours. METHODS: Consecutive cohorts of patients were treated according to a standard '3+3' design with escalating doses of plitidepsin at 4, 5 and 6mg/m(2). Additional 15 patients were recruited at the RD to further evaluate safety and pharmacokinetic associations with respect to age, dose level and toxicity...
