Abstract

While it is not the intent to argue that papilloma never develops in the conventionally accepted manner (proliferative growth from the wall of a pre-existing cavity) a new, perhaps alternative, genesis is suggested. The concept is that, beginning with the usual lobular structure of the breast, first by hyperplasia and then by coalescence of alveoli, seen earliest at the periphery of the lobule, spaces appear between the content of the lobule and the wall. By confluence of these spaces a larger cystic cavity is formed. Coalescence of alveoli through the body of the central mass, in the same way as at the periphery, develops the familiar pattern of “papilloma.” Following the earlier hyperplasia, regressive changes appear and may go on to complete disintegration of the papillary mass, leaving a smooth-walled cavity.
