ABSTRACT
The Abdominal Inflammatory Myofibroblastic Tumor [AIMT] is a rare tumor with unknown etiology which usually occurs in children and adolescents. It is composed of myofibroblastic spindle cells intermixed with inflammatory cells. We present four cases of AIMT. We herein present four cases of AIMT in different ages [range: 3.5 to 13 years] and in different organs [stomach, periduodenal, mesenteric, and colon]. There were two females and two males. The main symptoms were abdominal pain/mass/obstruction, vomiting, and weight loss. In all four patients, diagnosis was made by laparatomy and pathologic examination of excised mass lesion. Three patients underwent complete excision and no residual disease was present, one patient received chemotherapy due to tumor recurrences. The patients were followed up in average for four years. As the imaging and laboratory tests are non-specific, the diagnosis of AIMT is rarely made before surgery. AIMT should, therefore, be considered when a mass arises in an unusual location in the pediatric age group. Complete surgical resection should be performed whenever possible and the child should be kept on long-term follow-up

Parathyroid hormone-related protein producing pancreatic neuroendocrine tumors have been infrequently reported. Here-in, we report a case of an Iranian woman who had such a tumor during pregnancy, and gave birth to a female neonate with esophago-tracheal fistula and imperforated anus. Hypercalcemia was diagnosed at postpartum because of elevated serum calcium levels in the neonate and neurologic deterioration of the mother. Extensive literature review revealed 42 cases with pancreatic neuroendocrine tumors and hypercalcaemia. The clinical and laboratory findings of such patients are reviewed in this manuscript
