We report a case of primary extrarenal Wilms' tumour which, on histological examination, revealed a zone of hyalinized blastema adjacent to, and within the tumour capsule. The tumour showed a predominant stromal component. The presence of the hyalinized blastema adjacent to the tumour raises the possibility that some cases of extrarenal Wilms' tumour may have a precursor lesion.

With the application of endoscopic retrograde cholangio pancreatography (ERCP), the association of anomalous pancreatobiliary junction and choledochal cyst is being increasingly recognized. We describe here the ERCP findings in three patients who had this anomaly in association with fusiform (Type I) choledochal cyst. Two of our patients also had evidence of pancreatitis. The importance of ERCP in the preoperative assessment of such patients is highlighted.
A rare case of retroperitoneal extrarenal Wilms' tumor with an unusual presentation is reported. The tumor contained a large cystic component and mimicked ascites clinically.
A unique case of solitary infantile myofibromatosis arising in the omentum is presented. The essentiality of wide surgical resection to avoid recurrence is emphasised.
A young patient who had traumatic amputation of left arm developed extensive chylothorax on right side of chest. The pathophysiology appears to be left subclavian thrombosis secondary to gross sepsis of the amputation stump which resulted in occlusion of thoracic duct opening and chylothorax. The child was successfully treated by closed chest tube drainage.
Two infants with mesenchymal hamartoma of the liver are reported. This lesion clinically simulates a malignant neoplasm very closely and awareness is essential to avoid unnecessary major hepatic resections. The cases were successfully treated with simple enucleation.

A 4-year-old boy with unilocular hydatid cysts of spleen and liver was successfully treated by enucleation of both the cysts and salvage of the spleen. The conventional surgical treatment of choice for hydatid cyst of the spleen is splenectomy. The authors demonstrate that preservation of a spleen afflicted by hydatid disease is technically feasible and is recommended as the choice of treatment to obviate the well-recognized postsplenectomy complications especially in children.
A rare case of esophageal atresia associated with esophageal duplication cyst is reported. The cystic duplication was recognized and successfully resected at primary thoracotomy for repair of esophageal atresia. This case is believed to be the first reported instance where both lesions could be treated concomitantly at first thoracotomy.
A child with cystic duplication of the rectum containing ectopic duodenal mucosa and aberrant pancreatic tissue presenting as a chronic perianal fistula is reported. The duplication was removed by subtotal excision of the cyst along with mucosal sleeve resection from the common septum with the rectal wall.
Antenatal appendicular perforation leading to localized meconium peritonitis and intestinal obstruction is reported in a premature neonate. The baby was successfully treated by a limited ileocaecal resection.
