Primary hepatic tumours are rare in childhood. We observed nine cases between 1976 and 1995, of which eight were hepatoblastomas and one a mesenchymal hamartoma. A male-to-female ratio of 2:1 was noted; 78% of the cases occurred in children below 2 years of age. Five hepatoblastomas were of the pure epithelial type; mesenchymal components encountered in the mixed type were cartilage, bone, and spindle sarcomatous cells.

An 8-day-old female neonate was referred to pediatric surgical services for regurgitation of feeds since birth. Plain x-ray of the chest and abdomen with Ryle's tube in situ and contrast study confirmed the diagnosis of esophageal atresia at the cardiac end of the esophagus. The membrane at the cardiac end of the esophagus was excised employing a thoracoabdominal approach. This is the first case report of membranous type of esophageal atresia at the cardiac end of the esophagus to be reported in the English literature.
Rhabdomyoma is a rare benign tumor of striated muscle origin. Two distinct histologic groups, adult and fetal type, are recognized. So far only 66 cases of extracardiac rhabdomyomas (37 fetal and 29 adult) have been documented in the literature reviewed. The present report details a case of adult rhabdomyoma of the esophagus in an 8-year-old boy.
A 42-year-old man was operated with a clinical diagnosis of peptic ulcer but was found to have growth in the pyloric region. The pathology report on the gastrectomy specimen was Crohn's disease of the stomach with malignant lymphoma. Review of the literature indicates the rarity of this association.
