title: Characterization of two types of crystalloids in pleomorphic adenomas of minor salivary glands. A light-microscopic, electron-microscopic, and histochemical study.
abstract: Crystalloids have been previously described in salivary gland tumors. In order to ascertain the incidence of these structures, the authors reviewed a series of 294 minor salivary gland tumors. One hundred thirty pleomorphic adenomas were identified, and 6 of these contained crystalloids. No crystalloids were found in other benign or malignant salivary gland tumors. These six file cases and a recent seventh case containing crystalloids were studied by light and electron microscopy and with histochemistry. Two types of crystalloids were found. One case contained previously described tyrosine-rich crystalloids, and the other six contained crystalloids composed of radially arranged collagen fibers. Both types of crystalloids are further characterized and discussed.
