In vivo confocal microscopy in the daily practice of the dermatologic surgeon

New imaging methods, such as optical coherence tomography, magnetic resonance and high frequency ultrasonography, have been developed for use in dermatology. Among the new methods, in vivo reflectance confocal microscopy, has presented the fastest growth in large cutaneous oncology centers and has generated the greatest number of articles in the literature recently, due to its resolution – similar to histological resolution. In vivo confocal microscopy has been particularly useful given the many limitations of the dermoscopic diagnosis of cutaneous neoplasias, especially of achromic or hypopigmented lesions, lesions in the face or in mucous membranes. Some studies have also suggested considerable utility in the assessment of surgical margins and in determining the best area of the body for carrying out excisional biopsies. This study briefly describes how the confocal laser reflectance microscope works and discusses some of the issues that arise in its use in the daily practice of dermatologic surgeons.
