Histopathology (or histology) involves the examination of sampled whole tissues under the microscope. Pieces of tissue rather than whole organs are removed as biopsies, which often require smaller surgical procedures that can be performed whilst the patient is still awake but sedated.

What does pathology report include?

A pathology report is a document that contains the diagnosis determined by examining cells and tissues under a microscope. The report may also contain information about the size, shape, and appearance of a specimen as it looks to the naked eye. This information is known as the gross description.

What can be diagnosed by histopathology?

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.

How do you get samples for histopathology?

Collect the appropriate size (1 cm thick) representative specimen containing the active part of the lesion and apparently normal adjacent tissue. Handle the specimens gently—avoid collection artifacts. Preserve the specimen in adequate fixative (1:10 tissue:fixative ratio). Label the container properly.

How do you perform histopathology?

Overview of the steps in tissue processing for paraffin sections

1. Obtaining a fresh specimen. Fresh tissue specimens will come from various sources.
2. Fixation. The specimen is placed in a liquid fixing agent (fixative) such as formaldehyde solution (formalin).
3. Dehydration.
4. Clearing.
5. Wax infiltration.
6. Embedding or blocking out.

What is the difference between biopsy and pathology?

Looking at the tissue sample The medical staff who perform your biopsy place the specimen in a container with a fluid to preserve it. They label the container with your name and other details. A pathologist then describes how it looks to the naked eye. This includes the color, size, and other features.

What are the different types of specimen received and processed in histopathology?

For example, the following are some of the specimen types commonly received in a histopathology lab.

• Excision specimens (surgical biopsies), where whole organs or affected areas are removed at operation.
• Incisional biopsy specimens, where tissue is removed for diagnosis from within an affected area.
