A review of the literature reveals that Wilms tumor is rare in adolescence. At the time of diagnosis 78 per cent of children are less than 5 years old. Of 17 cases of Wilms tumor seen at the Ontario Cancer Foundation Clinic in Kingston from 1973 to 1975, 3 children were between 16 and 17 years old. Of 316 cases registered in Ontario with the Ontario Cancer Treatment and Research Foundation only 5 were in the 15 to 19-year age group. The possibility of Wilms tumor in patients beyond the usual age group is not considered as a differential diagnosis because of its relative rarity. Patients may present with features suggestive of neuroblastoma, renal cell carcinoma, hydronephrosis, cholecystitis, appendicitis and twisted ovarian cyst as seen in our 3 patients. In comparison, a review of 84 reported cases of renal cell carcinoma in children from 1934 to 1974 showed 5 cases in the 15 to 18-year age group.

This article highlights the surgeon's role in childhood cancer especially as it relates to local control of solid tumors, research, and surgical supportive care. There is a trend toward preresection chemotherapy, and rarely, radiotherapy. This may allow safer, less extensive, and function-preserving delayed resection in neuroblastoma, hepatoblastoma, bone tumors, and nephroblastoma in selected patients without negatively affecting outcome. Ultimately, complete resection for most tumors, even advanced neuroblastomas, significantly improves survival. Organ transplantation allows complete resection with good survival in children with otherwise nonresectable liver tumors. In non-Hodgkin's lymphoma, resection should not be attempted, except for localized disease and if complete resection is possible. Second-look procedures have limited value in lymphoma, but have an important role in germ cell tumors. The differentiation of typhlitis from appendicitis is critical in the neutropenic patient to avoid life-threatening complications. Studies of venous access devices show a clear benefit of totally implantable devices in preventing dislodgment and decreasing the rate of infection. Neuroblastoma models are fertile soil for research into tumor biology and novel treatment modalities. Surgeons continue to play crucial roles in childhood oncology.

The term "Western diseases" refers to those conditions that are rare or absent in underdeveloped areas of the Third World and increase in frequency with adoptions of Western customs. In adults, they include such common conditions as coronary artery disease, essential hypertension, appendicitis, cholesterol gall stones, and colon cancer. The best examples of Western diseases in the pediatric population are asthma, allergies, appendicitis, and inflammatory bowel disease. Limited data from sub-Saharan Africa suggest other pediatric surgical conditions may fall into this category, including hypertrophic pyloric stenosis, gastroesophageal reflux, perirectal abscess, anal fissure, gastroschesis, and neuroblastoma. Existing theories for the origins of Western diseases have postulated a role for decreased dietary fiber, improved hygiene, fetal programming, and a protective effect of tropical enteropathy. How these factors might relate to the rise of appendicitis, inflammatory bowel disease, and possibly other common pediatric surgical diseases in industrialized societies remains poorly understood. Further research is needed to better define geographical differences in common pediatric surgical conditions and to investigate how genetic and environmental factors interact to modify risk of disease. Understanding the molecular mechanisms that give rise to Western diseases could lead to new therapeutic and prevention strategies for some of the most common pediatric surgical conditions in industrialized countries.

Fetal imaging has dramatically impacted neonatal care by providing an advanced warning of many different congenital anomalies. The advancements and widespread use of fetal imaging has, however, increased the identification of various incidental findings that is creating new challenges for neonatal diagnosis and treatment. We report such a case where a fetal pancreatic neuroblastoma (NB) was incidentally detected by computed tomographic scan of the maternal abdomen. Primary pancreatic NB is a very uncommon childhood neoplasm that, to our knowledge, has never been previously reported in the English language presenting in either the prenatal or neonatal periods. A 21-year-old woman complaining of acute abdominal pain and carrying a 35 weeks' gestation fetus was referred for computed tomographic scan because of the concern of maternal appendicitis. That scan was inconclusive for appendicitis but did incidentally detect a fetal mass in the general region of the pancreas. At 36 weeks' gestation, the fetus developed signs of distress, which prompted a cesarean delivery. Neonatal workup confirmed the presence of an abdominal mass in the region of the pancreas, but precise anatomic localization was not possible. Also noted on neonatal workup were elevated urinary catecholamines consistent with a hormonal active tumor. These findings prompted an abdominal exploration of this neonate, which revealed a solid tumor contained in the distal pancreas. The mass was managed by an uncomplicated distal pancreatectomy. The neonate fully recovered, and histologic diagnosis revealed NB, whereas the postoperative urine catecholamines normalized. This case underscores the unintended clinical challenges created by widespread fetal imaging, while presenting the first prenatally diagnosed case in the English language medical literature and earliest treated patient with pancreatic NB.
