title: [Use and importance of cytology for tumor diagnosis in internal medicine].
abstract: Many fields of internal medicine give the assumption for the ingenious application of cytodiagnostics. The respiratory tract, the gastrointestinal system and the urinary passage are the most important groups of organs. A technically unobjectionable gaining of material is the basis for this. The examination of exfoliated cells and the fine needle aspiration biopsy are the technical variants. The close cooperation of a morphologically interested clinician with a clinically interested morphologist and the guaranty of the mutual control of cytology and histology yield a promising success method for the clinical differential diagnostics and for the early recognition of cancer.
