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, 1.8-20 cm). The median follow up for patients was 15 months (range, 1-108 months) Metastatic disease and local infiltration of surrounding tissues is common with poor prognosis in adult patients. Preoperative diagnosis is difficult because of the unhelpful
tumor markers in adults and the cellular heterogeneity of the
tumor which makes fine needle aspiration cytology unreliable. Histopathological review of the
tumor is essential for diagnosis. Pancreatoblastomas should be considered a differential diagnosis of solid and cystic
pancreatic neoplasms. Surgical resection of the
tumor is the treatment of choice with a variable combination with
radiotherapy and
chemotherapy.
