[Chievitz's organ (the juxtaoral organ): morphological and immunohistochemical studies].

The Chievitz's organ (juxtaoral organ) consisting of a long continuous mass of epithelial cells is located with its medial border by the lateral face of the buccinator muscle. It was successfully identified in 10 out of 40 corpses and histologically examined. Through immunohistological methods using markers like S-100, TPA, PAN, CK-13, NSE and vimentin the epithelial character in the centre of the parenchyma could be demonstrated as well as the marked innervation and vascular supply of the direct surroundings.
