What is Histopathology?

Histopathology tests utilize tissue samples gathered through procedures like endoscopy, colonoscopy, colposcopy, or surgical interventions such as a breast biopsy. Conditions diagnosed through histopathological examination encompass Crohn's disease, Uterine fibroids, Ulcerative colitis, cancer, infections, etc

How are Histopathological Tests Performed?

Histopathology tests are conducted by specialized doctors known as pathologists, who play a crucial role in examining tissues under a microscope to diagnose diseases. In this process, tissue samples undergo meticulous preparation by the pathologists, who cut them into thin layers called sections through processes such as biopsies. These sections are then stained and examined under a microscope to observe and document the intricate details of the tissue.

For certain diseases such as cancers, a rapid assessment is achieved through frozen sections, obtained during surgery, providing results within approximately 20 minutes. This quick evaluation is particularly useful in surgeries to assess tumor margins, assisting surgeons in deciding if additional tissue removal is necessary for complete cancer removal. The frozen section method is commonly employed during surgeries, and its application depends on the type of cancer being addressed and other relevant factors.

Additionally, for the evaluation of blood cancers and the identification of metastases in solid tumors, lymph nodes are often biopsied. In some cases, a bone marrow biopsy may also be required for a definitive diagnosis of various blood cancers. The meticulous and detailed process of histopathology tests is essential in providing accurate diagnoses and guiding medical decisions for effective disease management.

What can be diagnosed by Histopathology?

Histopathological tests, commonly performed by doctors, serve as a crucial diagnostic tool, particularly in identifying the presence of cancerous cells. Histopathologists play a pivotal role in examining tissue samples obtained through procedures like endoscopy, colonoscopy, colposcopy, or surgical interventions such as breast biopsies.

The insights gleaned from these tests answer crucial questions, such as the presence of cancerous cells, the exact types of cancer cells present, and the percentage of cancerous cells. This information is vital for determining appropriate treatment strategies.

Beyond cancer detection, histopathology is instrumental in diagnosing various diseases. For instance, it aids in identifying conditions like ulcerative colitis, Crohn's disease, uterine fibroids, and infections. The thorough examination of tissue samples, including lymph nodes, allows histopathologists to assess the spread of diseases and understand their extent.

This comprehensive diagnostic approach of histopathological tests enhances the medical community's ability to provide accurate and tailored treatment plans

What is the difference between biopsy and Histopathology?

Many people often use 'biopsy' and 'histopathology' interchangeably, but there are distinctions. A biopsy is the procedure of collecting tissue samples to assess for atypical cells, while histopathology is the study of these cell samples. In technical terms, a biopsy refers to the gathering of tissues, whereas histopathology involves examining the sampled tissue itself. Technically, a biopsy alone will not yield any insights about the health of an organ or individual.

Further investigation of the sections obtained using stains and microscopy are needed to detect diseases and evaluate the progression of a disease.

Notably, histopathology can extend beyond biopsies to encompass the analysis of entire organs. Consequently, when your doctor discusses the results, they may refer to it as either a biopsy report or a histopathology report. For instance, if the examination involves studying samples from a complete organ, it technically falls under histopathology rather than a conventional biopsy.

Pathologists may additionally employ other sampling techniques alongside histopathology to diagnose cancers like leukemia and arrive at a prognosis. A few of the techniques are:

- molecular techniques: analyze tissues & cells at a molecular level

- Immunohistochemistry: utilizes antibodies for specific markers on cancer cells

- Chromosomal Studies: reveal gene rearrangements and genetic changes

Common Histopathological Tests Include:

1. Frozen Biopsy:

A frozen biopsy, also known as an intraoperative consultation, is a rapid diagnostic procedure performed during surgery. It involves the quick freezing and microscopic examination of tissue samples to help surgeons make immediate decisions. The entire process typically takes about 15-20 minutes, allowing surgeons to proceed with the necessary surgical intervention without significant delay.

2. Fetal Autopsy:

A fetal autopsy is a comprehensive examination of a fetus who has passed away in the womb, during birth, or shortly after birth. This examination helps to determine the cause of death, identify any congenital abnormalities, and provide valuable information for future pregnancies.

3. Bone Marrow Biopsy:

A small sample of the bone marrow is extracted to assess bone marrow health and detect blood disorders, leukemia and lymphoma. The Bone Marrow Trephine Biopsy Panel involves obtaining a cylindrical core of bone marrow tissue using a trephine biopsy needle, offering a comprehensive assessment of bone marrow architecture and aiding in the diagnosis & management of various hematologic conditions like leukemia, lymphoma & myeloma.

4. Bone Biopsy:

Used to assess health of bone structures and detect bone diseases, infections & bone cancer

5. Skin Biopsy: Skin tissue is removed for microscopic examination. It is used to assess skin conditions and detect cancers, infections & autoimmune disorders.

6. Biopsy With AFB Stain:

A special staining method used in biopsies to identify acid-fast bacteria. It is used to diagnose Tuberculosis

7. Appendix Biopsy:

Performed to detect inflammation, infection and tumors in appendix

8. Direct Immunofluorescence Test:

This test involves labeling antibodies with fluorescent dyes for visualization under a microscope. It can aid in the detection of autoimmune diseases, skin disorders and certain infections.

9. Cervical Biopsy: Performed to detect cervical cancer, precancerous changes & infections.

10. Biopsy culture and sensitivity:

Removed tissue samples are grown in a culture to identify infectious agents and test their response to antibiotics. This can help pinpoint the specific pathogen causing an infection and its susceptibility to treatment.

11. Gallbladder Biopsy: Used to identify inflammation, stones, or cancer and assess gallbladder conditions

12. Kidney Biopsy: Performed to evaluate kidney diseases and detect infections, tumors & other kidney diseases.

13. Liver Biopsy Panel: Performed to detect tumors and assess liver diseases such as Cirrhosis, Hepatitis, etc

14. Endometrial Biopsy:

It can be used to assess hormonal changes and detect uterine conditions & cancers.

15. Grocott Methenamine Silver (GMS) Stain:

It aids in the evaluation of infertility, detection of tumors and overall assessment of testicular health.

Other noteworthy Histopathological tests include Endoscopy, Colonoscopy & Colposcopy which are used to detect abnormalities, tumors, inflammation & assess the health of the gastrointestinal tract & cervix respectively.

Additionally, tests such as Acute Lymphoblastic Leukemia (ALL) FISH Panel, and Transurethral Resection Of The Prostate (TURP), Histoplasma Antibody Immunodiffusion and IHC (Immunohistochemistry) P53 can offer valuable insights into conditions ranging from infectious diseases to cancers.

Components of Histopathological Report

Histopathology reports are usually detailed, encompassing the following details:

- description of tissue appearance

- a diagnosis

- a synoptic report of case findings

- Pathologist’s remarks (if any)

These reports are intricate but crucial for understanding the disease. Interpretation is vital for prognosis, considering factors such as tumor size, severity, and grade, along with indications of cancer spread.

Prognostic indicators assist in predicting survival rates or recovery, and grading involves scoring cells based on their abnormality under a microscope. Higher grades signify more significant abnormalities. It's important to distinguish grading from staging, which assesses cancer location and spread within the body. Consulting a specialist healthcare provider is essential for patients to comprehend the findings of Histopathology tests effectively.
