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 ").
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.
They are frequently seen in hippocampal pyramidal cells. [5] An experimental model of Hirano body formation has been reported, using a genetically altered strain of the slime mold Dictyostelium discoideum. [6] Hirano bodies have been noted as a function of age without obvious underlying neurodegeneration. [7]
Histopathology is the branch of histology that includes the microscopic identification and study of diseased tissue. [ 5 ] [ 6 ] It is an important part of anatomical pathology and surgical pathology , as accurate diagnosis of cancer and other diseases often requires histopathological examination of tissue samples.

Cells of the subcommissural organ, which are specialized in the secretion of glycoproteins (see below), are arranged into two layers: a superficial layer called the ependyma and an underlying layer called the hypendyma. [1] The ependyma consists of long, columnar cells that release their secretions into the ventricular cerebrospinal fluid.
It is also at this step that the pathologist selects areas that will be processed for histopathology. The eye can sometimes be aided with a magnifying glass or a stereo microscope, especially when examining parasitic organisms. Histopathology – the microscopic examination of stained tissue sections using histological techniques.
The cells of meristematic tissue are similar in structure and have a thin and elastic primary cell wall made of cellulose. They are compactly arranged without inter-cellular spaces between them. Each cell contains a dense cytoplasm and a prominent cell nucleus. The dense protoplasm of meristematic cells contains very few vacuoles.
According to the Journal of the History of the Neurosciences, Dr. Lewy became interested in studying more about the brain , because of the discovery that Alois Alzheimer made in 1906. The article mentions that the third reported case of Alzheimer's disease had histological structures that happened to be similar to Lewy body histology slides ...
