Dermatoscopy is a method that provides 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 for examining formations such as basal cell cancer, seborrheic keratosis, blue moles or ordinary moles.
Moles on the skin that lead to the formation of skin cancers (melanotic and non-melanocytic tumors) known to be challenging in diagnosis. Differentiation of melanotic and non-melanostic pigmented skin lesions is important in terms of treatment and follow-up. In other words, it helps the diagnosis to be made by the physician in suspicious lesions and provides a ” I”Dermatoscopy plays an important role in the decision of whether it is necessary to take it.
The follow-up of moles on the skin is important for early diagnosis of malignant melanoma. One of the most effective methods of recognizing malignant melanoma is self-control. However, because people cannot see some parts of their bodies, they may miss the changes in their “I”. Dermatoscopy plays an important role in this regard. The moles on the skin of the person are recorded. In the next control, it is understood whether there is a change in the “I”s.
How Does Dermatoscopy Work?
The main principle of dermatoscopy is to ensure the transparency of the skin surface and to allow the observation of suspicious structures at appropriate magnification. In other words, dermoscopy is a technique that allows the recognition of skin surface and sub-surface structures that cannot be seen with the naked eye in the early diagnosis of melanoma and in the differential diagnosis of pigmented skin lesions. It looks very irritating to the naked eye. “I” When examined with a dermatoscope, it can be understood that it is very innocent. On the contrary, a “me” that looks unproblematic can be found to be risky when viewed with a dermatoscope.
The most important practical application for dermatoscopy is to distinguish early stages of melanoma from benign formations. First of all, it is decided whether the examined mole is melanocytic or not. If it is decided that it is melanotic, benign moles should be distinguished from melanoma. Asymmetrical moles, presence of many colors, irregular blood drops are features of melanoma.
The importance of dermoscopic examination has increased in the differentiation of subtle melanomas from melanocytic nevi and pigmented skin lesions. Dermatoscopy is an instrument consisting of a light source that will provide skin transparency and lenses that will provide standard growth. Adequate illumination enables observation of subcutaneous structures with sufficient magnification. It has also been used in some diseases such as non-pigmented skin tumors, inflammatory skin diseases, and scabies.
