Summary
The fine structure of the so-called mesonephroma of the uterine cervix was compared with that of endocervical adenocarcinoma.
Mesonephroma tubules have a peculiar type of basement membrane composed of numerous stratified basal laminae. The lining of the tubules shows a sinuous outline of the lumen between individual cells of the epithelium. In contrast, the tubules of endocervical adenocarcinoma have a double-layered basement membrane and their outlines are regular.
The outlines of the neoplastic tubules and the structure of the basement membranes are the main ultrastructural features distinguishing these two varieties of cervical tumour.
