Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In addition to Reflectance confocal microscopy (RCM), it currently use 2 less expensive dermatoscopes that also allow in vivo diagnosis: super-high magnification dermoscopy (D400) and Fluorescence-Advanced videodermatoscopy (FAV).

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In our current practice, many patients have benefited from these 3 imaging modalities for benign and malignant lesions.
Therefore, our aim is to analyze these images and compare their performance in the diagnosis of benign and malignant pigmented lesions.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Patients with a pigmented skin lesion
Patients with a pigmented skin lesion of more than 3mm diameter which have benefited systematically of all 3 imaging techniques at the same time, followed by either a surgical excision or annual imaging monitoring.
