Hence, unicellular organisms have simple structures while most multicellular organisms have very complex structures. The surgeon sent a specimen of the cyst to the pathology department for staining and analysis to determine its histologic subtype. The Biology Project: Cell Biology - Excellent teaching resources from the University of Arizona. Initially, the biologist selects a particular part of an organ which should be studied. Cytology tests may be used for diagnosis or for screening: A diagnostic test is only used for people who have signs, symptoms, or some other reason to suspect that they might have a particular disease (like cancer). For example, cytology on a neck node that confirms metastatic squamous cell carcinoma from an oropharyngeal primary would be sufficient to direct ongoing management, whereas in lymphoma, a larger biopsy or the entire node may be required to evaluate nodal architecture in order to decide optimal first-line management. The interval between the previous biopsy and the biopsy taken for this study was at least 4 weeks, to reduce the patient burden. In 86% of the cases histology and cytology provided the same diagnosis, whereas in 7 patients (14%) histologic evaluation modified the diagnosis.
