Neurogenic appendicopathy--role of enterochromaffin cells in its pathogenesis.
One hundred cases of neurogenic appendicopathy were histochemically studied for schwann cells and enterochromaffin cells. The early phase, labelled as neuro-appendicopathy (29 cases) showed minimum to moderate number of extraepithelial enterochromaffin cells without neurogenous hyperplasia. In 53 cases, there was intra and submucosal neural hyperplasia with increase in the extraepithelial enterochromaffin cells, representing the active phase. The late phase known as obliterative neurogenic appendicopathy, showed extraepithelial enterochromaffin cells and schwann cell proliferation of variable grades (18 cases). The origin of extraepithelial enterochromaffin cells is related to proliferating nerve plexus, rather than epithelial enterochromaffin cells.
