Dermatoskopiát

Dermatoskopiát, also known as dermatoscopy or epiluminescence microscopy, is a non-invasive diagnostic technique used by dermatologists to examine skin lesions. It involves using a handheld magnifying device called a dermatoscope, which is equipped with a light source and a lens. This device allows for a magnified, illuminated view of the skin's surface, including structures not visible to the naked eye.

The primary purpose of dermatoskopiát is to aid in the diagnosis of skin conditions, particularly melanoma and other skin cancers, as well as benign pigmented lesions like nevi. The dermatoscope uses polarized or non-polarized light and often a liquid immersion medium (like oil or water) to reduce surface reflection and improve visualization of subsurface structures. This allows the dermatologist to observe specific patterns and features within the lesion, such as pigment networks, dots, globules, streaks, and regression structures.

By analyzing these dermatoscopic features, a dermatologist can differentiate between benign and potentially malignant lesions. This can help to determine whether a lesion needs to be removed for biopsy or can be monitored. Dermatoskopiát is also utilized for the diagnosis of non-pigmented lesions, such as basal cell carcinomas and squamous cell carcinomas, as well as inflammatory skin conditions and parasitic infestations. It is a valuable tool that enhances diagnostic accuracy and can potentially reduce the number of unnecessary excisions of benign lesions.
