Only data from medical records and formalin-fixed paraffin-embedded tissue blocks will be collected from patients in this cohort. Patients with skin or mucosal melanoma and dysplastic nevi which have been already excised are eligible. FFPE tissue blocks with MPATH-Dx Class 1-2 vs Class 3-5 will be collected in approximately 1:1 ratio

Only data from medical records, formalin-fixed paraffin-embedded tissue blocks and cytologic slides will be collected from patients in this cohort. Patients with skin or mucosal melanoma and dysplastic nevi which have been already excised are eligible. FFPE tissue blocks with MPATH-Dx Class 1-2 vs Class 3-5 will be collected in approximately 1:1 ratio

Patients with pigmented lesions on the skin or mucosa who are referred for excisional biopsy will be offered to apply investigated non-invasive adhesive system on their lesion just before the excisional biopsy. After biopsy cytological slides and FFPE tissue blocks will be prepared. All three types of obtained samples will be investigated separately (adhesive patches, cytologic slides and FFPE tissue blocks) for genetic markers whereas cytologic slides and FFPE tissue blocks will be processed also routinely and regular cytologic and histopathologic report will be generated.

The already registered on the market adhesive skin patch will be applied and removed for several times on the pigmented skin (or mucosal) lesion just before the preplanned excisional biopsy after local anaesthesia have been already administered. Excisional biopsy and local anaesthesia are not the part of this study and will be carried out according to local practice

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".

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

•Assessment of the sensitivity and specificity of a complex of molecular genetic studies applicable for non-invasive differential diagnosis of benign and malignant melanocytic neoplasms of the skin and mucous membranes in comparison with a standard histological examination

Assessment of the sensitivity, specificity, positive and negative prognostic significance of the developed molecular genetic method for non-invasive differential diagnosis of benign and malignant pigmented neoplasms of the skin and mucous membranes in comparison with clinical diagnosis with an naked eye by an oncologist or dermatologist
