    Dynamische Optische Kohärenztomographie Melanozytärer Läsionen : Nicht-invasive Analyse von GefäßparameternThe differential diagnosis of melanocytic lesions is of great importance due to the rise in melanoma incidence, high morbidity and mortality in later stages and demanding differential diagnosis, especially in early stages. Currently, by a clinical- dermoscopic approach, early melanomas may be overlooked, the proportion of melanomas and dysplastic nevi overestimated, and a significant number of performed biopsies may be unnecessary. This prospective, clinical, multicentre study investigated the potential of dynamic optical coherence tomography (D-OCT) to distinguish melanocytic lesions based on their microvascularisation. The study hypothesis was the existence of vascular differences between nevi, dysplastic nevi, melanomas, adjacent skin and according to potential influencing factors, including age, sex, and lesion location. The results were compared to the current diagnostic gold standard of a clinical-dermoscopic and histological examination. Further, to confocal laser microscopy and line-field confocal optical coherence tomography. With excellent predictive values, D-OCT distinguished nevi from melanomas. Several significant and explainable differences were observed concerning nevus subtypes, participant sex, age and lesion location but allowed no solely vascular- based distinction. Based on our findings, we created an algorithm to standardise a D-OCT-based differential diagnosis of melanocytic lesions. Improving the current clinical-dermoscopic diagnostic approach and avoiding invasive biopsies are central research interests. D-OCT visualises skin morphology and vascularisation in vivo and in real time. Its non-invasive approach prevents unnecessary biopsies, wound formation, infection, scarring and biopsy-related pain. It has a high resolution and appropriate penetration depth. Scanning is quick, handling is simple, and it is suitable for the skin of every ethnicity and all lesion locations and architectures. Furthermore, it offers an individualised therapeutic approach and a potentially earlier melanoma detection with a consequent reduction of morbidity and mortality and an economic benefit. Further confirmation by high-quality, multicentric studies is recommended. If promising, a combinatory device with D-OCT, camera, and dermoscopy tool should be considered for diagnosing (unclear) melanocytic lesions
