Dermatoscopy – skin under the magnifying glass
Dermatoscopy is examination, during which specialists examine the skin growths in multi point increase. As the world is growing rapidly in the presence of a variety of skin diseases, this procedure is becoming increasingly important not only if you have already experienced serious skin problems, but also to prevent them.
What dermatoscopy is capable of?
Dermatoscopy is a non-invasive, harmless examination, which allows to investigate the upper layers of the skin. This exam is basically conducted to distinguish between benign and malignant conditions. Investigations carried out with two devices – optical or manual dermatoscope or digital dermatoscope.
Dermatoscopy lets to detect cancer in its formation or in the very early stages, for example, when even the worst forms, such as melanoma, cure results can be very good – up to 97-100%.
In the most cases, an experienced physician “to the naked eye” can tell whether the arrangement is benign, malignant or suspicious. If there is a suspicion of melanoma specialist sends to an oncologist. It should be remembered that the melanoma diagnosis is always confirmed by histological examination only after the conclusion of receipt.
In recent years, dermatoscopy is no longer just ontological examination, but also for various inflammatory skin diseases investigating a standby. Dermatoscopy is widely used in hair to determine the causes of the problems and assess the effectiveness of treatment. This diagnostic method is great help in diseases such as psoriasis, seborrheic dermatitis, Rosacea, Vitiligo and other skin problems. Like a dermatoscope can help detect scabies, which is a relatively common infection.
The optical or manual dermatoscope
The device consists of a cylindrical shell with the integrated lens system, the light source, contact glass and handle the electrical power source. Optical dermatoscope mainly allows to look at the skin in 10-16 times high magnification. Since this device is relatively inexpensive and simple to use, it is appropriate to use in small physician practices.
The main optical dermatoscopes drawback – it is not possible to observe the dynamics of formations, especially if the companies do not. This can be done only when the device is added to the camera,the you have to take a photo of the arrangement, and then to save the captured computer. However, this process is complicated enough, so the more convenient is digital dermatoscope.
The optical arrangement dermatoscopes the increase is less than the digital device. However, the diagnosis is still being used successfully in the following dermatoscopes. However, if the exam questions arising from unclear, additional tests may be performed with a digital dermatoscope.
The benefits of digital dermatoscopes
For years, the diagnosis of skin lesions is used in digital dermatoscopes. This structure is much more complicated, but not diagnostic process is not, moreover, provides an opportunity to look at the formations 150 times high magnification. Digital dermatoscope is a special lens system, which is a polarizing options, a light source, the contact glass, highly sensitive digital cameras and computer systems, with special programs for data analysis.
Therefore, the digital dermatoscope possible to make a visual documentation of skin lesions, and preservation of computer memory to make operational analysis of the dynamics of formation, compared with the previous new businesses. If a doctor gimmick seems suspicious, but it is not yet clear signs of malignancies, it can be checked and re-evaluate how it is after a certain time has changed. Such an examination are used to avoid unnecessary worries and operations.
Digital dermatoscope have installed the program itself may take measurements formation. The program record formation size, color, texture, many other parameters, after which you can more accurately determine the nature of the arrangement. This program is primarily meant for pigmented lesions investigation and observation, however, tend to be more and other benign and malignant skin tumors.
Therefore, in order to make an accurate diagnosis and appropriate treatment would mean a critical role and importance of the investigation has specialist knowledge and competence.
As people willingly surrenders to the sun caresses, sometimes too insatiable, dermatoscopy is the exam, which is recommended to carry out preventive, rather than only when a complaint has arisen. People who have fair skin, lots of moles and other growths on the skin, had a malignant disease, stained burning of the sun, the sun has been changes in the skin, such as pigmented spots should take prophylactic dermatoscopy once a year.
It is the best to take preventive dermatoscopy month after tanning season. It is better to do it in the fall, winter, spring at the latest. Dermatoscopy’s examinations should not be taken in the summer when the sun affects the moles may vary slightly. During tests in the summer, it can produce biased results. Of course, if the complaint is not taken into account neither the season nor the circumstances, but go to the doctor.
If, for example, itching, ulceration gimmick, it changes color, grows rapidly, then seek professional help. The above-mentioned changes must necessarily be a reason to help clarify the specialist and, if necessary, use the dermatoscope.
How is the exam handled?
At first there will be a talk to your doctor, you will tell him about the arrangements, which are likely to cause a concern for you. Dermatoscopy’s specialist examinations will start with suspicious lesions viewing to find out if there are concerns about the possibility of malignancies. It is usually determined by several parameters.
There are formations that are looking at a specialist without a dermatoscope can help right away to say that there can not be nothing and malignant mole or arrangement does not need to be touched. If you have a number of suspicious growths, they will be thoroughly discussed with the dermatoscope assistance, entered into the system, for you will be a map of moles created, so that later they can be observed in dynamics.
Even if you do not have any suspicious arrangement, a specialist will inspect all the skin in order to make sure of it.
Hurry to dermatoscopy, if …
- formation appeared in a place where it has not previously been;
- been a change in a pigmented arrangement – changed the shape, color, size, surface, appears itchy or sore feeling;
- notice the formation of accompanied by scaly to heal and it formed a scab, wounds, ulcers or vascular network.
