Prenatal diagnosis has been performed more frequently in Japan recently, but is still less popular than in the United States or Europe. Legal arrangements, insufficient economic support, and insufficient medical information provided to future parents may explain this difference. The acceptability of prenatal diagnosis, based on the concept of the cost of side effects and elective abortion, was found to be similar when examined through decision analysis and direct survey. Amniocentesis was considered useful for more than half of couples in Japan when the incidence of chromosomal abnormality is more than 0.5% and proper information about the decision to undergo this examination is provided to the pregnant woman and her family.
A case of carcinoma ex pleomorphic adenoma arising in the soft palate is reported. The tumour presented had enlarged gradually over 10 years and finally occupied the oral cavity. The patient was admitted to our hospital due to disturbance of her speech and swallowing, and a sudden haemorrhage from the tumour. The initial pathological diagnosis by open biopsy was benign pleomorphic adenoma. After total resection, histological examination revealed that the tumour was composed partly of benign pleomorphic adenoma and partly of an adenocarcinomatous component. The carcinoma cells with prominent nucleoli were spheroid or polygonal in shape, and frequently formed ductal structures with areas of necrosis. Mitoses were also found. These findings showed that this tumour was a secondary carcinoma which had developed in a preexisting pleomorphic adenoma.
