Description of intervention(s) / exposure
Use of Confocal reflectance Microscopy in diagnosis of Non-melanoma skin cancers as compared to histological diagnosis
1-Confocal micrscopy involves a 10 to 25 minute session, where an adherent probe is placed over the lesion of interest. The operator of the microscope then proceeds to generate images of the lesion. This can take anything from 10 to 25 minutes, depending on the size of the lesion. At the end of the session the probe is removed. No sensation other than slight pressure from the weight of the probe will be felt by the patient.
2-All participant will have a confocal imaging of their skin lesion, prior to having the lesion removed, either by biopsy or by excision.
Intervention code [1] 256549 0
Not applicable
Comparator / control treatment
Histological evaluation of tissue samples after excision or biopsy, which typically takes 4 to 5 working days. The histological evaluation is carried out by a pathologist blind to the findings of the confocal imaging.
Control group
Active

Outcomes
Primary outcome [1] 258519 0
Comparability of Confocal Reflectance Microscopy to Histopathology
This will be evaluated by use of sensitivity, specificity, and negative predictive value calculations. The aim of the calculations is to determine if there is comparability between histology and confocal diagnoses.

Secondary outcome [1] 264332 0
Positive predictive value of Confocal Reflectance Microscopy in determining margins of spread of skin malignancies
Assessed through calculation of positive predictive value of confocal imaging, as compared to histology (gold standard).

Summary
Brief summary
Purpose of the study is to determine the place, if any, of bifocal tissue scanning in diagnosis of skin cancers as compared to tissue biopsy. We hope to determine if a) there is a better and easier way of diagnosis of skin lesion other than biopsy and b) if there is a reliable method of determining the limits of spread of the skin lesion to reduce the need for repeated surgeries.
