Structural Description of Skin Biopsies With Dynamic Full-field Optical Coherence Tomography on Suspected Basal Cell Carcinoma Lesions, a Pilot Study (DOCTOBA)

Basal cell carcinoma (BCC) are the most frequent skin cancers. Their incidence is constantly increasing. BCC diagnosis is first clinically suspected and then confirmed following histological examination of either a skin biopsy or the excisional specimen. Surgery is the first-line treatment and some procedures (notably Mohs surgery) require extemporaneous histological analysis of the edges to ensure a complete excision. Such on-site histopathological examination can be time consuming and associated with decreased sensitivity. Skin imaging techniques have already been tested to overcome these limitations and seem promising. Although some of them - such as confocal microscopy - are already even used in vivo, there is to date no report of the use of full-field optical coherence tomography for the diagnosis of BCC.The DOCTOBA study intends to describe direct histopathological examination of fresh skin biopsy or excisional specimen with dynamic full-field optical coherence tomography.

Inclusion Criteria:- patient > 18 years of age who received skin biopsy or excision of basal cell carcinoma suspected lesion between start study date and primary completion dateExclusion Criteria:inability to perform dynamic full-field optical coherence tomography observation at the moment of skin biopsydiagnosis of basal cell carcinoma disproved
