Use of reflectance confocal microscopy to diagnose occult basal cell carcinoma: 2 case reports

Clinical and dermoscopic diagnosis of facial pigmented and nonpigmented lesions is sometimes challenging. Face and scalp are chronic sun-exposed sites, and signs of photoaging1 can be associated with the development of precancerous or malignant lesions.2-4 Noninvasive imaging techniques such as reflectance confocal microscopy (RCM) allow us to better diagnose and monitor equivocal melanocytic and nonmelanocytic lesions, particularly on specific sites such as the face.5
