Digital Dermatoscopy — Mole Mapping

Computer-aided examination of pigmented skin lesions using a high-sensitivity digital dermatoscope and risk-analysis software. The device photographs each mole or pigmented spot at high magnification, then automatically scores its risk profile — distinguishing benign nevi from potentially concerning lesions at a stage when treatment is most effective. Images are stored digitally so changes can be tracked visit to visit. The examination is painless, requires no preparation and is suitable for children. At Dermo Písek the dermatoscope is also used to select the optimal removal method: lesions classified as low-risk can often be treated with the clinic's CO2 laser rather than surgical excision, avoiding stitches entirely.

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 even if they are imperceptible to the naked eye. 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. At Dermo Písek the examination also serves as a triage tool before lesion removal. A low-risk intradermal nevus identified under the dermatoscope can be removed with the clinic's fractional CO2 laser — a non-contact, suture-free method — rather than surgical cutting. This choice is only possible when the lesion's nature has been confirmed beforehand. Who should consider this examination: anyone with moles larger than 5 mm, moles with irregular borders or uneven colouring, moles that have changed in recent months, or a personal or family history of atypical nevi or melanoma. It is also recommended before any planned mole removal procedure. The examination is painless, takes around 15–25 minutes depending on the number of lesions, and requires no preparation. It is safe and fully appropriate for children.
