[Histogenesis and development of membranous basal cell adenoma of the salivary gland].
OBJECTIVE
To investigate the histogenesis and development of membranous basal cell adenoma in the salivary glands.


METHODS
A histological and immunohistochemical study was carried out on 12 cases of membranous basal cell adenoma in the salivary glands.


RESULTS
In 4 cases, multiple focal proliferations of striated ducts in the surrounding salivary gland were conspicuous, which allowed tracing the development of the tumors from their origin. The earliest changes were characterized by hyperplasia of the basal cells of striated ducts. Continuous ductal proliferation lead to the formation of microadenomas.


CONCLUSIONS
Proliferation of basal cells of the striated ducts apparently participate in, and play a main role in the histogenesis of some membranous basal cell adenomas of the salivary glands.
