Cytopathology is frequently, less precisely, called "cytology", which means "the study of cells". [2] Cytopathology is commonly used to investigate diseases involving a wide range of body sites, often to aid in the diagnosis of cancer but also in the diagnosis of some infectious diseases and other inflammatory conditions.

Specifically, in clinical medicine, histopathology refers to the examination of a biopsy or surgical specimen by a pathologist, after the specimen has been processed and histological sections have been placed onto glass slides. [17] This contrasts with the methods of cytopathology, which uses free cells or tissue fragments.
Specifically, in clinical medicine, histopathology refers to the examination of a biopsy or surgical specimen by a pathologist, after the specimen has been processed and histological sections have been placed onto glass slides. In contrast, cytopathology examines free cells or tissue micro-fragments (as "cell blocks ").
Histopathology: microscopic appearance of invasive ductal carcinoma of the breast. The slide is stained with an antibody (immunohistochemistry) against the oncogene Her2neu. The dark-brown reaction indicates that this tumor over-expresses this gene. Cytopathology: microscopic appearance of a Pap test.
Anatomic pathology: areas included here are histopathology, cytopathology, electron microscopy, and gross pathology. Medical Laboratory, which typically includes the following areas: [5] Clinical microbiology: This encompasses several different sciences, including bacteriology, virology, parasitology, immunology, and mycology.

Overlap between anatomic and clinical pathology is expanding to molecular diagnostics and proteomics as we move towards making the best use of new technologies for personalized medicine. [ 3 ] Clinical pathologists may assist physicians in interpreting complex tests such as platelet aggregometry, hemoglobin or serum protein electrophoresis , or ...
The scientific branch that studies and diagnoses diseases on the cellular level is called cytopathology. Cytopathology is generally used on samples of free cells or tissue fragments, in contrast to the pathology branch of histopathology, which studies whole tissues. Cytopathology is commonly used to investigate diseases involving a wide range ...
Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses.In this technique, a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells that, after being stained, are examined under a microscope ().
