Histopathology is the diagnosis and study of diseases of the tissues, and involves examining tissues and/or cells under a microscope. Histopathologists are responsible for making tissue diagnoses and helping clinicians manage a patient's care. Histopathology alludes to the infinitesimal assessment of tissue so as to contemplate the appearances of illness. In particular, in clinical medication, histopathology alludes to the assessment of a biopsy or careful example by a pathologist, after the example has been prepared and histological segments have been put onto glass slides. Interestingly, cytopathology looks at free cells or tissue smaller scale parts (as "cell squares").
