- Dermoscopy is an important noninvasive technique that helps in the diagnosis of melanoma and can aid in assessing its thickness before surgery.

- Results indicated that certain types of blood vessels are linked to thicker melanomas and that specific vessel types may indicate ulceration or dermoscopic regression, though the study faced challenges with case selection and identifying vessels in pigmented melanomas.
