Digital Dermatoscopy — Mole Mapping

Digital dermatoscopy at Dermo Písek is a non-invasive, computer-assisted examination of pigmented skin lesions — moles, nevi, pigmented spots, seborrhoeic keratoses and other surface changes. The clinic uses a high-sensitivity dermatoscope equipped with a precision digital camera and integrated risk-scoring software that analyses each lesion against established morphological criteria including asymmetry, border irregularity, colour variation and diameter.

During the session the practitioner moves the dermatoscope over each lesion to be assessed. The camera captures magnified images that are displayed on-screen in real time, and the computer algorithm rapidly assigns a risk classification to each lesion. All images are stored digitally in the patient's file, creating a longitudinal record that makes subtle changes — new asymmetry, darkening at the margin, a new satellite lesion — visible on the next visit…

The clinical value of this approach is significant: melanoma, the most aggressive form of skin cancer, is associated with a survival rate that drops steeply once it spreads beyond the skin. Dermatoscopic surveillance allows it to be identified and treated at a stage when removal is curative. Equally, many lesions that appear worrying without magnification are confidently classified as benign under the dermatoscope, avoiding unnecessary surgical excisions.
