Screening & Diagnostic Tests
Dermoscopy is a diagnostic test that allows a provider to see growths and spots on the skin more clearly. It is also known as dermatoscopy, epiluminescence microscopy, or ELM, or surface microscopy. The provider uses a dermatoscope — an instrument with a special magnifying lens and light source — that is held near the skin. Sometimes a thin layer of oil is applied to the skin, making it more transparent and easier to see. Then a photograph of the spot or growth may be taken.
This test can improve the accuracy of detecting skin cancers early. It can also assess a growth to determine if it is benign, or non-cancerous, without the need for a biopsy.
