[Ultrastructure of adenoid-cystic carcinoma as a sign of malignity (comparison of ultramicroscopical investigations concerning adenoid-cystic carcinoma and adeno-carcinoma of salivary glands) (author's transl)].
The ultrastructure of Adenoid-cystic carcinoma of salivary glands analysed by 7 cases is compared with ultrastructure of Adenocarcinoma. Both carcinomas have corresponding secretory cells. The dysregulation of secret production is typical in Adenoid-cystic carcinoma and Adenocarcinoma and based on defective differentiation and missing innervation of carcinoma cells. The diversity of tumour-cells, increased by nesecretory cells, based on large cytogenetic prospection of acinary and ductulary epithelium of salivary glands. Based on the ultramicroscopical correspondence of secretory cell-types in both carcinomas the malignity of the Adenoid-cystic carcinoma is founded.
