title: Clinicopathological review of pancreatoblastoma in adults.
abstract: 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.
