As a dermatologic diagnostic tool, dermoscopy is mainly used in dermatology to examine skin diseases, and can observe minute skin changes that are not detectable by the naked eye, helping doctors to diagnose various skin problems more accurately. Conventional dermoscopy techniques use a non-polarized light source and often require the application of a medium (e.g., gel) to the skin to prevent the effects of reflections on the skin surface during observation. This is relatively cumbersome and susceptible to ambient light. On the other hand, modern medical dermatoscopes have a polarized light pattern that prevents gross reflections on the skin surface allowing to observe tiny skin details without medium imposition. Medical dermatoscopes also typically have higher magnification, allowing for a clearer view of skin structures.


Definition and Importance of Medical Dermoscopy

Medical dermoscopy has a wide range of applications in the field of dermatologic medicine. Dermoscopy can assist in the diagnosis of a variety of skin tumors. Many pigmented diseases also require the use of dermoscopy, including vitiligo, apatite, anemia, and so on. Doctors can also use dermoscopic images of androgenetic alopecia to determine the type of alopecia and to assess follicular atrophy.
Dermoscopy is able to put in-depth observation of the structure under the stratum corneum and even the superficial dermis, observing details that cannot be observed by the human eye and improving the accuracy of diagnosis of skin lesions.

Dermoscopy Uses

Dermoscopy uses are extensive in dermatological examinations. By magnifying skin tissues, dermoscopy reveals changes in skin blood vessels and pigmentation, assisting doctors in making more precise diagnoses of skin conditions. Dermoscopy has a wide range of applications, primarily used for examining various skin lesions on the body, such as seborrheic dermatitis, pityriasis rosea, and molluscum contagiosum. Additionally, during clinic visits, doctors can observe the fine structures on the skin’s surface and even detect potential skin cancer lesions. For instance, melanoma often appears under dermoscopy with jagged, irregular, or blurred borders, often accompanied by blue-white globules.


The Role of Medical Dermoscopy in Skin Cancer Screening
Early-stage skin cancer is usually confined to the surface of the skin or superficial tissues. Through timely treatment, such as surgical excision and photodynamic therapy, the condition can be effectively controlled and prevented from further deterioration. The treatment of early skin cancer is relatively simple and the treatment cost is relatively low. Therefore, early detection and treatment are of great importance in reducing the psychological and economic burden of patients.
And dermoscopy has an irreplaceable role in early screening of skin cancer. Dermoscopy is easy to operate, takes less time for examination and has high magnification. This makes dermoscopy ideal for large-scale skin screening programs.

Impact of Medical Dermoscopy on Patient Care
As a non-invasive examination tool, medical dermoscopy does not cause any discomfort to the client during the examination. Especially for patients with ulcerated skin lesions, dermoscopy can provide clear dermatoscopic images without ensuring any contact with the patient’s skin. This greatly reduces patient pain and helps increase patient satisfaction and trust. Moreover, patients can gradually learn to use dermoscopy for self-examination by themselves under the educational guidance of their doctors and observe their recovery in real time.


Guidelines for the Operation of Medical Dermoscopy
Before using a dermatoscope, it is necessary to disinfect and sterilize the patient’s skin area to be observed and ensure that the skin is dry. Then, place the dermatoscope above the skin to be observed and adjust the focus until the field of view is clear. After each use, disinfect the contact surface of the dermatoscope’s probe to prevent cross-infection. Additionally, during storage, a lens cap should be worn to avoid scratching or damaging the lens.


Training and Education in Medical Dermoscopy
Medical dermoscopy is only a testing tool, the diagnosis still needs the judgment of the doctor, experienced doctors can often give accurate judgment results based on dermoscopic images. Doctors who have just started to enter the clinic naturally need to receive continuous training from the hospital, grow their experience in practice, and grow into a doctor who can make reasonable judgments. Only in this way can a virtuous circle be formed to promote the sustainable development of dermatology.

The Use of Dermoscopy in the Diagnosis of Specific Skin Lesions
Dermoscopy allows visualization of pigmentary changes in the epidermis, reticular layer of the dermis, and changes in the vasculature of the superficial mesodermis. This technique has been widely used for the early diagnosis of malignant melanoma and differential diagnosis with other cancers. Dermoscopy can also assist in the diagnosis of a variety of inflammatory diseases such as lichen planus, psoriasis, follicular keratosis, and urticarial vasculitis. Dermoscopy is able to differentiate scarring alopecia from non-scarring alopecia, and the common forms of pemphigus vulgaris and alopecia areata can also be visualized in dermoscopic images.

Innovations and Future Trends in Medical Dermoscopy
With the application of AI in various fields, future electronic dermatoscopes will be integrated with big data models. Through continuous learning by artificial intelligence, future dermatoscopes will possess skin analysis capabilities. By utilizing image matching and data analysis, dermatoscopes can predict the type and nature of skin lesions, aiding doctors in making more accurate diagnoses. Additionally, they can dynamically collect patient information and transmit it to remote experts for diagnosis, enabling patients in medically underserved areas to access high-quality dermatological services. As technology continues to advance, portable dermatoscope devices will become more widespread, serving as important tools for home self-monitoring and health management.


Key Uses and Benefits of Dermoscopy
Medical dermoscopy is an important tool in modern dermatologic diagnosis and is widely used in clinical diagnosis. Dermoscopy is easy to operate, has a short detection time and relatively low cost, making it suitable for widespread use in dermatology outpatient clinics. It is also non-invasive and does not cause damage to the skin, which makes it highly acceptable to patients. With the development of technology, dermoscopy will have a wider and wider range of applications and higher accuracy.

A dermoscopy is a device that allows the examination of skin lesions with magnificationand illumination. By revealing subsurface structures and patterns that are not visible tothe naked eye. It can improve the diagnose accuracy of skin lesions, such as melanoma,basal cell carcinoma, seborrheic keratosis, etc.

There are two main types of dermoscopy: Non polarized and polarized dermoscopy.We’ve fitted most of our dermoscopys with polarized and non-polarized light. They canbe used in multiple skin structures.

Non-polarized contact Mode

In non-polarized mode, the instrument can provide information about the superficialskin structures, such as milia-like cysts, comedo-like openings, and pigment in theepidemis.

The dermoscopy requires applying a liquid such as mineral oil or alcohol to the skin andplacing the lens in contact with the skin. This reduces surface reflection and enhancesthe view of subsurface structures.

Polarized contact Mode

In polarized mode, the instrument allows for visualization for deeper skin structures,such as blood vessels, collagen, and pigment in the dermis.

The dermoscopy does not need to be in contact with the skin or use any liquid. Theirpolarized light can help to eliminate surface reflection and allow visualization ofvascular structures.

Polarized non-contact Mode

The dermoscopy can also use polarized light to examine the skin without direct contact.

In polarized non-contact mode, the instrument allows for examination infected areasand lesions that are painful for the patient, or the difficult to contact pigmented lesions,such as nails and narrow areas.

The contact plate should be removed in this mode, and it does not require applying aliquid to the skin. As it doesn’t require pressure or fluid application on the skin, it canalso avoid cross-contamination and infection risk.

Compared with visual inspection, the dermoscopy can be used to capture and store skin lesion photos, which play an important role in early skin cancer examination.

The dermoscopy allows the examination of skin lesions with magnification and illumination. This can be greatly avoiding the factors that cause interference to visual detection. Such as lighting, skin color, hair and cosmetics.

Several studies have demonstrated that dermoscopy is useful in the identification of melanoma, when used by a trained professional.

It may improve the accuracy of clinical diagnosis by up to 35%
It may reduce the number of harmless lesions that are removed
In primary care, it may increase the referral of more worrisome lesions and reduce the referral of more trivial ones

A 2018 Cochrane meta-analysis published the accuracy of dermoscopy in the detection.

Characteristics of the dermatoscopic structure of the skin lesions include:

• Symmetry or asymmetry
• Homogeny/uniformity (sameness) or heterogeny (structural differences across the lesion)
• Distribution of pigment: brown lines, dots, clods and structureless areas
• Skin surface keratin: small white cysts, crypts, fissures
• Vascular morphology and pattern: regular or irregular
• Border of the lesion: fading, sharply cut off or radial streaks
• Presence of ulceration

There are specific dermoscopic patterns that aid in the diagnosis of the following pigmented skin lesions:

• Melanoma
• Moles (benign melanocytic naevus)
• Freckles (lentigos)
• Atypical naevi
• Blue naevi
• Seborrhoeic keratosis
• Pigmented basal cell carcinoma
• Haemangioma
