Pathology of the salivary glands: The contribution of electron microscopy

摘要: Electron microscopy has a limited role in the diagnosis of primary salivary gland tumors, although it can be helpful metastatic lesions possible origin. The diversity subtypes as well range histomorphology within any one subtype, is unparalleled other human tumor. This and their relative infrequency causes diagnostic problems for pathologists. Ultrastructural techniques have been major importance determining inter-relationship these tumors classification purposes, revealing subtle variations common cellular differentiation pathways, organization tumor cells, displaying extracellular matrix materials establishing criteria each many subtypes. also valuable non-neoplastic disease an increasing experimental studies involving tissue from animal parenchyma.
