چکیده
Berry, Colin L., Keeling, Jean, and Hilton, Clare (1970). Archives of Disease in Childhood, 45, 229. Coincidence of congenital malformation and embryonic tumours of childhood. Examination of the records of cases of neuroblastoma, nephroblastoma, hepatoblastoma, and teratoma has not revealed a significant association between neoplasia and malformation. An increase in 'local' abnormalities in sacrococcygeal teratomata might be explained by local growth effects. The significance of the definition of malformation, the validity of comparisons between 'general incidence' figures for malformations, and those obtained in tumour-bearing patients is considered.

Malignant Soft Tissue Tumours
Introduction Tumours of soft tissue are mostly benign lesions of connective tissue in children. A number of aggressive malignant tumours that require multimodal therapy do occur, however, usually including surgical management. These malignant soft tissue sarcomas (STSs) are relatively rare in childhood, contributing approximately 5–8% of childhood malignancies (approximately 850–900 children an...
متن کاملBenign hamartoma of the liver.
Sheehan (1930) when describing a malignant liver tumour in a young child, first brought together a number of such tumours previously described under a variety of names, such as 'sarcoma', 'endothelioma' or 'angeiosarcoma', and pointed out that they were probably all derived from rests of undifferentiated mesenchymal cells and were in fact embryonic growths. The tumour he described consisted lar...

The nude mouse has several advantages for the study of human tumours. Compared to adult cancers (Sharkey et al., 1978), paediatric tumours have been less extensively xenografted into nude mice (Helson, 1982). The only large series was published by Neely et al. (1983). Most infantile solid tumours are considered embryonic because of the age at which they occur and their potential for differentia...
متن کاملSeminar on chemotherapy for malignant tumours in childhood.
The clinical treatment of all forms of cancer rests increasingly on the combination of surgery, radiotherapy, and chemotherapy. Each of these disciplines has its limitations. Radiotherapy can only be applied to a limited field in adequate dosage for cure, except in the treatment of tumours extremely sensitive to X-radiation. Chemotherapy is so far limited by the generally toxic effect on all th...
متن کاملCK19 is a sensitive marker for yolk sac tumours of the testis
BACKGROUND Malignant germ cell tumours are the most common malignant tumours in young men. They are histologically divided into seminomas and non-seminomas. Non-seminomas are further subdivided into embryonic carcinomas, yolk sac tumours, chorionic carcinomas, and teratomas. For the therapeutic management it is essential to differentiate between these histological subtypes. METHODS Investigat...
