Summary
This summary is machine-generated.Immunohistochemistry (IHC) markers are crucial for diagnosing melanoma, aiding in differential diagnosis, and assessing prognosis. These markers help predict treatment response, especially in complex cases.
Area Of Science
- Oncology
- Pathology
- Dermatology
Background
- Melanoma presents a significant challenge due to rising incidence, high mortality, and treatment costs.
- Accurate diagnosis and assessment of prognostic factors are vital for effective melanoma management.
- Immunohistochemistry (IHC) offers critical information for melanoma diagnosis, particularly in complex scenarios.
Purpose Of The Study
- To systematically review and consolidate information on IHC markers used in melanoma.
- To provide an accessible resource for clinicians and pathologists on IHC applications in melanoma diagnosis, differential diagnosis, prognosis, staging, and treatment.
Main Methods
- A comprehensive literature search was performed.
- One hundred and forty-seven studies were included in the systematic review.
- Results were thematically organized by specific IHC markers.
Main Results
- Melanocytic differentiation markers (S100, SOX10, Melan-A/MART1) are consistently positive in melanoma.
- HMB-45 and PRAME assist in differentiating benign from malignant melanocytic lesions.
- MITF, Ki67, BRAF, and PD-L1 correlate with prognostic factors (e.g., Breslow thickness, ulceration) and treatment response.
Conclusions
- IHC markers are indispensable for melanoma diagnosis and differential diagnosis, especially when histopathology is atypical.
- IHC aids in identifying prognostic factors crucial for patient management.
- IHC can assist in predicting patient response to various melanoma treatments.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
