Dermatoscopy is a method that allows a clearer examination of the layers of the skin without damaging the skin in skin lesions with discoloration.
Dermatoscopy is used for the early diagnosis of skin cancer called melanoma, as well as basal cell cancer, seborrheic keratosis, blue mole or ordinary skin cancer. It is also used to examine formations such as moles.
It is known that moles on the skin that lead to the formation of skin cancers (melanostic and non-melanostic tumors)are challenging in diagnosis. Differentiation of melanostic and non-melanostic pigmented skin lesions is important in terms of planned treatment and follow-up. In other words, it helps the physician to diagnose suspicious lesions and dermatoscopy plays an important role in deciding whether a "mole" needs to be removed.
Following up moles on the skin is important for the early diagnosis of malignant melanoma. One of the most effective methods for detecting malignant melanoma is self-checking. However, since people cannot see some parts of their bodies, they may miss the changes in their "I". Dermatoscopy plays an important role in this regard. Moles existing on the person's skin are recorded. At the next check-up, it will be understood whether there is a change in the "moles".
How Does Dermatoscopy Work?
The main principle of dermatoscopy is to ensure the transparency of the skin surface and to observe suspicious structures at appropriate magnification. is to enable. In other words, dermoscopy is a technique that allows the recognition of skin surface and subsurface structures that cannot be seen with the naked eye in the early diagnosis of melanoma and the differential diagnosis of pigmented skin lesions. An "I" that seems very disturbing to the naked eye can be understood to be very innocent when examined with a dermatoscope. On the contrary, a "mole" that appears to be unproblematic can be determined to be risky when examined with a dermatoscope.
The most important practical application for dermatoscopy is to distinguish the early stages of melanoma from benign formations. First of all, it is decided whether the mole examined is melanostic or not. If it is decided to be melanostic, benign moles should be distinguished from melanoma. Asymmetrical moles, presence of many colors, irregular blood drops are the characteristics of melanoma.
Nowadays, the importance of dermoscopic examination has increased in distinguishing subtle melanomas from melanostic nevi and pigmented skin lesions. Dermatoscopy is a tool consisting of a light source to ensure skin transparency and lenses to provide standard growth. Adequate illumination allows observation of subcutaneous structures with sufficient magnification. It has also begun to be used in some diseases such as non-pigmented skin tumors, inflammatory skin diseases and scabies.
