Dermoscopy in Melanoma Detection: A Comprehensive Guide
Malignant melanoma is a serious form of skin cancer that begins in melanocytes, the cells responsible for producing melanin. Early detection is crucial for successful treatment and improved survival rates. Dermoscopy has emerged as a powerful tool in the diagnosis and management of melanoma, offering dermatologists and patients alike a non-invasive method to examine skin lesions in detail.
What is Dermoscopy?
Dermoscopy, also known as epiluminescence microscopy or dermatoscopy, is a non-invasive diagnostic technique that allows for the detailed examination of skin lesions. It combines powerful lighting with magnification to provide a clear view of structures beneath the skin surface that are not visible to the naked eye.
Types of Dermoscopes
1. Contact Dermoscopes: These require direct contact with the skin and often use a liquid interface to improve visualization.
2. Non-contact Dermoscopes: These allow examination without touching the skin, reducing the risk of infection transmission.
3. Digital Dermoscopes: These capture and store high-resolution images for future comparison and analysis.
What is malignant melanoma dermoscopy?
Malignant melanoma dermoscopy is a specialized diagnostic technique that uses a dermatoscope to examine suspicious skin lesions for signs of melanoma skin cancer. Under dermoscopic examination, melanoma typically shows specific characteristics:
- Asymmetrical shape and pattern distribution
- Irregular borders with jagged or blurred edges
- Multiple colours (brown, black, red, blue or white)
- Atypical pigment network with irregular lines
- Blue-white veil appearance in raised areas
- Irregular dots or globules of varying sizes
Abnormal blood vessel patterns
Let me explain more specific details about melanoma dermoscopic features that are particularly important for diagnosis.
Key melanoma patterns under dermoscopy include:
Blood Vessel Patterns: Irregular, dotted vessels, Thick or twisted vessels, Areas showing vessel regression, Pink or red discolouration.
Pigmentation Features: Uneven colour distribution, Dark brown to black areas, Blue-grey areas indicating deep pigment, Areas of regression showing white scarring.
Structural Elements: Streaks at lesion edges, Irregular dots/globules, Crystalline structures, Areas of regression.
Important Changes to Monitor: Growth or expansion, Colour changes, New structural features, Border changes.
Differentiating Melanoma from Benign Lesions
Melanoma features: Asymmetry in multiple axes, 3 or more colours within one lesion, Blue-white veil presence, Irregular vessel patterns.
Benign lesion features: Symmetrical patterns, 1-2 uniform colors, Regular, organized networks, Consistent border pattern.
Scoring Systems in Melanoma Dermoscopy
ABCD Rule: A: Asymmetry (0-2 points). B: Border irregularity (0-8 points). C: Color variety (1-6 points). D: Different structural components (1-5 points).
7-Point Checklist
Major criteria (2 points each): Atypical network,Blue-white veil,Atypical vascular pattern.
Minor criteria (1 point each): Irregular streaks, Irregular dots/globules, Irregular blotches, Regression structures.
Documentation Best Practices
Essential steps: Take baseline photos, Record the exact lesion location, Document size measurements, Note specific features present, Plan follow-up intervals.
These features, when viewed through a dermatoscope, help dermatologists identify melanoma at early stages, leading to better treatment outcomes. The technique is precious because it allows visualization of structures below the skin surface that aren't visible to the naked eye.
What to Expect During a Dermoscopic Examination
1. Cleansing of the skin area. 2. Application of a liquid interface (if using a contact dermoscope). 3. Examination of the lesion under magnification. 4. Documentation of findings. 5. Discussion of results and recommendations.
The Future of Dermoscopy
Ongoing research is focused on improving dermoscopic techniques and integrating them with other diagnostic tools. Emerging areas include 3D dermoscopy for improved structural analysis, Integration with genetic testing for personalized risk assessment, and Development of more sophisticated AI algorithms for automated screening.
Dermoscopy has revolutionized the early detection of melanoma, significantly improving patient outcomes. As technology advances, dermoscopy's role in skin cancer management is likely to expand, offering even greater precision in diagnosis and monitoring. Regular dermoscopic examinations, combined with self-awareness and prompt professional evaluation of suspicious lesions, remain the cornerstone of effective melanoma prevention and management.
Artificial Intelligence in Dermoscopy
Recent advancements in AI have led to the development of algorithms that can: Assist in melanoma detection, Provide risk assessments, Support dermatologists in decision-making.
A 2020 study published in the Journal of the American Academy of Dermatology found that AI-assisted dermoscopy improved melanoma detection rates by 23% compared to dermoscopy alone.
Dermoscopy in Overall Skin Cancer Screening
Dermoscopy plays a crucial role in comprehensive skin cancer screening protocols. It's particularly effective when combined with total body photography for high-risk patients.

What is malignant melanoma?
Malignant melanoma is a serious skin cancer that starts in melanocytes. It is also known as cutaneous melanoma. This skin cancer is much dangerous due to its rapidly spread to other organs if it is not controlled at an early stage.
Melanoma can appear in anywhere on the skin, but for people with lighter skin, melanoma is more likely to start on the chest and back in men and on the legs in women. The arms, face and neck are other common areas both in men and women. People with darker skin have a lower risk of developing melanoma in these more common areas. Melanoma even can happen in the eyes, while it is rarely to form inside body, like in throat or nose.
What is the cause of melanoma?
The cause of all melanomas is not exactly clear. But melanomas risk increase with exposure to ultraviolet light. Ultraviolet light, also known as UV, comes from sun or solariums. UV radiation can damage the DNA in skin cells, causing mutations that cause the cells to grow uncontrollably and form cancerous tumors.
Melanoma commonly happens especially in tanning, and sunburn during childhood. So it is helpful to reduce the risk of malignant melanoma by limiting the exposure to UV light.
Common high risk groups
The common high risk groups include: a previous melanoma comes back, a history of the sunburns, a family history of melanoma, fair skin or red hair, having many moles or atypical moles, a weakened immune system and so on.
The risk of melanoma appears to be increasing for people under 40, especially women. It is important to understand the high incidence of melanoma in people to help to prevent it. If people find a suspected person, then he should seek medical attention as soon as possible. Melanoma can be successfully treated when it is caught in early stage.
Symptoms of melanoma
There are some common signs and symptoms of melanoma including the following characteristics:
Asymmetry: one half of a mole or birthmark does not match the other half.
Size: Melanomas feature in larger size than normal moles, often exceeding 6mm in diameter.
Color: Melanomas may display different or multiple colors or shades, like brown,black,pink,red,blue, white even mixed color.
Border: melanoma may has irregular, scalloped, notched, or blurred borders.
Pain: Some melanomas may be painful or tender to the touch. Sometimes the spot will bleed and ooze fluid.
The appearance of new and atypical spots on the skin is the most important warning sign of melanoma. And other important warning sign is the existing spots have changed in color, size and shape. However, there may be one or two unusual characteristics of melanoma. Atypical changes on skin should be pay more attention to.
Survival rates for malignant melanoma
If diagnosed and treated early, malignant melanoma has a high cure rate, and the five-year survival rate for localized melanoma is about 98%. It includes the stage 0, stage I and stage II of malignant melanoma.
If it is not founded in the early stage, and it reaches to stage III of regional melanoma , the survival rate of malignant melanoma is about 63%.
However, if malignant melanoma is not treated until it has reached a more advanced stage and has spread to other parts of the body, such as the liver, lungs or brain is more serious and challenging to treat and has a lower survival rates.The five-year survival rate for stage IV melanoma is about 22%.
No matter how, use a dermoscopy to detect the atypical spots is necessary in case of any chance for evolution of malignant melanoma. Under the dermoscopy, dermatologists can detect and diagnose malignant melanoma much easily and accurately.
Identify the characteristics of malignant melanoma by using dermoscopy
Under the dermoscopy, it is clearly to display the features of malignant melanoma. Such as, by using dermoscopy, malignant melanoma usually clearly shows Irregular edges or borders and multiple colors. And malignant melanoma commonly appears in abnormal pigment distribution and structure, or atypical vascular distribution. Special signs such as granular areas and small blue and white papules may occur. Dermoscopy can precisely distinguish the points of malignant melanoma from benign lesions such as nevus.
Dermoscopy in the diagnosis of malignant melanoma
Dermoscopy is a dependable and aiding medical technique by skin doctors to detect the melanoma. Dermoscopy combines a powerful lighting system and high quality magnify lens to enhance the view of deeper skin and some hard-to-reach locations by naked eyes. The whole process of skin examination under dermoscopy without any side effective or adverse reactions. Dermoscopy can assist professional doctors to make early diagnosis of malignant melanoma without unnecessary biopsies and surgeries. Dermoscopy helps skin doctors to determine the clinical stage of the mass. What’s more, during the whole process of detection or treatment, as a monitor, dermoscopy can observe the progression of lesions. Dermoscopy greatly helps skin doctors to evaluate the effectiveness of surgery or other treatment of malignant melanoma.
Dermoscopy in public self-examination
Dermoscopy is usually designed to a small electric device which is convenient to handheld or easy to take photo by compatible with phones and tablets. Dermoscopy gains a very popularity both in hospital and in home. Dermoscopy can easily identify the malignant melanoma in professional hands. There are some main points when people use dermoscopy in public self-examination.
Firstly, correct operation and usage is necessary.
Secondly, during the use of dermoscopy, it needs to keep precautions and observations.
Thirdly, as soon as suspicious lesions are detected by dermoscopy, then it needs to seek medical treatment promptly.
Fourthly, people should cooperate with professional doctors for diagnosis and treatment after self-examination by dermoscopy if any atypical lesions founded.
Skin health is very significant to every one. Detection of malignant melanoma is really important, especially there being negligence in its early stage. With the help of dermoscopy, it increases much more confidence for dermatologists to diagnose and treat malignant melanoma and other skin diseases. In addition, more and more people use dermoscopy to examine skin conditions. Especially, high risk groups of malignant melanoma should even more often use dermoscopy for regular self-examination.
