This is a post study histology analysis from previously obtained pathology slides.

This is a post study histology analysis. Pathologists will use digital histology slide scans of suspicious nevus/nevi obtained from previously conducted studies to provide histopathology gradations of histological features as outlined in the Orlucent histology atlas (LBL0713 Histopathology Atlas for Grading of Dysplastic Nevi and DEF0713-1 Histopathology Definitions for LBL0713).

INTER-PATHOLOGIST READER STUDY

This is a data collection study. Study success is considered when the interpathology agreement is improved when compared to the agreement identified in Elmore et al. \[5\]. \[(classes/agreement): class I (eg, nevus or mild atypia) / 92% (95% confidence interval 90% to 94); class II (eg, moderate atypia) / 25% (22% to 28%); III (eg, severe atypia or melanoma in situ) / 40% (37% to 44%); IV (eg, pathologic stage T1a (pT1a) early invasive melanoma) / 43% (39% to 46%); and V (eg, ≥pT1b invasive melanoma) / 72% (69% to 75%).\]

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".
