Dermoscopy examination is the examination of a patient’s skin using a dermatoscope. It essentially allows the use of a skin microscope that magnifies dozens of times, through optical magnification and polarization patterns, so that the deeper layers of the skin can be viewed. In the diagnosis of skin diseases, dermoscopy can help doctors observe subtle pigment and vascular structural changes that cannot be observed with the naked eye, thus providing a comprehensive understanding of the skin lesions of skin diseases. For example, dermoscopy can observe the typical features of basal cell carcinoma, such as uneven pigmentation, dilated capillaries, and scaling, which can help doctors determine whether it is basal cell carcinoma.


Basic Principles of Dermoscopy Examination
The IBOOLO DE-4100 and DE-3100 Dermatoscopy Optical Magnification Systems magnify skin lesions up to ten times through a combination of multiple glass lenses. Both dermatoscopes utilize the principle of polarized light, which enhances the collection of transmitted light by adjusting the direction of light polarization to reduce the interference of reflected light from the skin surface. This technology allows the dermatoscope to penetrate deep into the skin tissue and observe the structure and characteristics of the epidermis and dermal papillary layers.

Dermoscopic Features of Basal Cell Carcinoma
Dermoscopy can acutely capture subtle color distinctions and changes in skin lesions, and therefore, dermoscopy has significant advantages in the diagnosis of skin diseases such as pigmented nevi, malignant melanoma and basal cell carcinoma. The following is an example of dermoscopic examination of basal cell carcinoma.
Dermoscopic features of basal cell carcinoma mainly include the following aspects:
Large blue-gray ovoid nests: this is one of the classic dermoscopic features of pigmented basal cell carcinoma, which is manifested by the appearance of multiple blue-gray ovoid structures of varying sizes in the lesion area.
Multiple blue-gray spherules: these spherules are usually distributed in a non-aggregated fashion and are another classic dermoscopic feature of basal cell carcinoma.
Spoke-like areas: Spoke-like areas appear as structures radiating from the center of the lesion to the periphery.


Importance of Dermoscopy Examination for Early Detection of Basal Cell Carcinoma
Basal cell carcinoma, a kind of malignant tumor originated from basal-like cells, is one of the most common skin malignant tumors, and its incidence rate is very high.BCC grows slowly but has the characteristic of local infiltrative growth, which is capable of destroying tissues and organs, and even threatens the patients’ lives in serious cases.
Dermoscopy plays a crucial role in the early detection of basal cell carcinoma. Dermoscopy examination can quickly capture many typical features of basal cell carcinoma, such as dendritic blood vessels, superficial short capillary dilatation, bleeding ulcers and so on. In addition, dermoscopy can also assess the infiltration depth and scope of basal cell carcinoma, which provides an important basis for the formulation of treatment plan.

IBOOLO Dermatoscope
IBOOLO has different series of dermatoscopes that offer different options for dermatoscopic examination. DE-200, DE-300 and DE-400 are pocket dermatoscopes that are compact and can be carried around. The DE-200, DE-300 and DE-400 are handheld dermatoscopes that can be used to view lesions directly through a window or to connect to a cell phone via a magnet. the DE-200, DE-300, and DE-400 are relatively inexpensive and have polarization, making them ideal for those who require only basic dermatoscopic functionality. the DE-3100 and DE-4100 are relatively inexpensive and have polarization, making them ideal for those who require only basic dermatoscopic functionality. The DE-3100 and DE-4100 are more expensive and have a variety of illumination sources and brightness adjustments, making them ideal for professionals.


Dermoscopy Procedure
The following is the procedure for a dermoscopy from start to finish. First, the surface of the patient’s skin that needs to be examined needs to be cleaned to ensure that it is dry and free of oil and dirt. Next, the probe of the dermatoscope is attached to the skin surface that needs to be observed. Keep the distance between the probe and the skin, adjust the focus until the image is clear to start observation. You can connect the dermatoscope to your cell phone to save photos of skin lesions. The doctor can judge the disease based on the skin pigmentation and blood vessel changes in the dermatoscope window, and suggest the appropriate treatment plan for the patient.

Advantages of the Dermoscopy Procedure
The entire process of dermoscopy usually takes less than 10 minutes, making it a quick and easy procedure. It enables doctors to obtain detailed information about the skin surface in a short period of time. Moreover, dermoscopy is a non-invasive and non-invasive diagnostic method that does not cause any damage to the skin or any discomfort to the patient, making it easier for the patient to accept this method of examination.


Dermoscopy Examination and Specialized Training
Dermoscopy is only an examination tool to provide professionals with a good viewing field. The final result of the examination still largely depends on the experience as well as the knowledge of the doctor. Therefore, it is important for healthcare professionals to receive systematic training on the basic principles of dermoscopy, its operation and the dermoscopic features of common skin diseases. There is a wide variety of skin diseases and new diseases and variants are constantly emerging. Healthcare professionals need to continually update their knowledge base on the latest dermoscopic diagnostic techniques and research findings by attending seminars and training courses.

Cleaning your dermoscopy after usage is important to prevent cross-contamination and infection. The cleaning method may vary depending on the type and model of your dermoscopy, so you should always follow the manufacturer’s instructions. However, some general steps are:

• Turn off and disconnect your dermoscopy from any power source or device.

• Wipe off any visible dirt or debris from the dermoscopy with a soft cloth or tissue.

• Disinfect the dermoscopy with an alcohol-based wipe or spray, or a disinfectant solution recommended by the manufacturer. Make sure to cover all surfaces, especially the lens and contact plate.

• Let the dermoscopy air dry completely before storing it in a clean and dry place.

• Do not use abrasive or corrosive cleaners, solvents, or detergents that may damage the dermoscopy.

• Do not immerse the dermoscopy in water or any liquid, unless it is waterproof and designed for immersion.

You should clean your dermoscopy after each use, or at least once a day if you use it frequently. You should also check your dermoscopy regularly for any signs of damage or malfunction, and contact the manufacturer or service provider if needed.

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
