Blue Nevus

This is an observational study in adult males and females utilising skin condition measurements using the LumAssure Raman device. Data will be used to determine accuracy under the ROC curve (AUCROC) of the LumAssure device for differentiating between benign and cancerous skin conditions. The measurements will provide data which will be used to establish spectral parameters for different skin conditions. Measurements will be benchmarked against diagnoses from medical specialists, and when available confirmed with histological data.
The main question it aims to answer is :
What is the accuracy, in terms of the area under the ROC curve (AUCROC) of the LumAssure device for differentiating between benign skin conditions and skin cancers in adult males and females? Participants include males and females aged ≥18 years who are undergoing assessment of a skin condition (a lesion or rash) by a dermatologist, general practitioner, or plastic surgeon. Participants' attending the clinics will have their skin conditions examined by a clinician. The LumAssure device will then be used to measure Raman spectra of skin conditions and marked by the clinician. The Raman measurements will be benchmarked against skin condition assessment and, where available, diagnosis by a dermatologist, general practitioner, or a plastic surgeon, and for those lesions undergoing biopsy, confirmed with histology data.

The goal of this clinical trial is to learn if the Sonablate High Intensity Focused Ultrasound device can be safely used to treat patients with Chronic Venous Incompetence (CVI) including those with venous malformations of the periphery meaning legs, abdomen, chest or back. Examples of CVI are varicose veins, vascular congestion, venous ulcer, venous clusters, venous anomalies, mixed malformation, Klippel-Trenaunay Syndrome, CLOVES, Syndrome, Blue Rubber bleb Nevus Syndrome. HIFU is a non-invasive treatment as opposed to current treatment options which include incisions, needle penetration, wire insertions or catheter insertions.

This is a multicenter, ambispective, low-interventional clinical study evaluating molecular genetic markers for non-invasive differential diagnosis of benign and malignant pigmented skin and mucosal neoplasms. In retrospective cohorts genetics markers will be identified. In prospective cohort non-invasive adhesive system will be tested to identify malignant or benign lesions with prespecified sensitivity and specificity compared to other non-invasive techniques (i.e. dermoscopy) and using histopathological examination as a "golden standard".
