Abstract
The autopsy protocols of 25 cases with tumors were examined. Thyroid, ovary and intestinal cysts, lipoma, fibroadenoma, cervical polyp,papilloma of the skin, hemangioma, lymphangioma, hemangioendothelioma, neuroblastoma and struma comprised the subject of this study. Sixteen cases (64%) were associated with congenital malformations and 111 anomalies were found in the group with tumor. Lymphangioma was usually coincident with hypoplastic thoracic organs, non-structural heart anomalies, and urogenital anomalies, while the cases with chromosome aberration occurred with structural heart anomalies. In some cases, the definition of congenital tumors was difficult to determine, having no difference with non-tumorous pathologic changes of the cells in spite of macroscopical tumorous proliferation. It is suggested that some tumors might be included in the category of congenital anomalies. The significance of congenital tumor in relation to congenital anomalies was emphasized, but the sequene of the tumor in the postnatal period was difficult to evaluate at present.
