Brief summary
OCTAV is a medical device class I, not CE marked, based on a new technique for high-resolution imager (cell) internal microstructures of all types of biological tissues in vivo or ex vivo, to a depth of penetration 800 .mu.m. It allows to explore the epidermis, the dermo-epidermal junction and middle dermis in a totally non-invasive (direct contact with the tissue without sampling).
Detailed description
At the coming of the patient in Dermatology for resection / biopsy of the tumor (usual practice), for the study, an image of the tumor will be performed with the OCTAV device (about 5 minutes) for the study. Then, according to usual practice, resection / biopsy will be performed. This study aims to validate the clinical relevance of this device to characterize the 3 main skin cancers and to obtain the necessary data for the implementation of future clinical trials.
Interventions
In vivo skin imaging performed by placing the tip of the OCTAV device directly in slight contact with the skin of the patient.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity | Day 1 | Sensitivity measures the proportion of positive skin cancers (according to the OCTAV device) that are correctly identified as such (according to gold standard : histology) |
| Specificity | Day 1 | Specificity measures the proportion of negative skin cancers (according to the OCTAV device) that are correctly identified as such (according to gold standard : histology) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Measure of the thickness of the different skin layers (mm) | Day 1 | Only for the non skin cancer group. Theses measures will identify the different skin layers (Epidermis, Dermis, Subcutaneous tissue, Cross-section) |
