Adenomatoid tumor of the fimbrial endosalpinx: report of two cases with discussion of histogenesis.

Two asymptomatic cases of adenomatoid tumor, confined to the lamina propria of the tubal fimbria, are presented, and their location within strictly Müllerian territory is offered as indirect evidence for the Müllerian origin of this lesion. To stress the individuality of this distinct entity, the name of Müllerian mesothelioma is suggested.
