ABSTRACT

In vivo reflectance confocal microscopy (RCM) is a non-invasive method, imaging cellular structures in living skin at a level close to the histological resolution. It is easier to diagnose melanocytic and non-melanocytic skin tumors especially in difficult cases when RCM features have been identified. Determination of the cellular features, presence of cellular and structural atypia with RCM allows the discrimination of benign and malignant lesions. Preoperative differential diagnosis of malignant lesions, determining preoperative lesion borders in complicated cases, identification of local recurrence after excision of malignant lesions, monitoring the treatment efficacy in patients using topical treatment and who can not be operated, are the main areas of RCM in tumoral lesions. Besides, RCM is helpful in the establishing the diagnosis of inflammatory disease like psoriasis, contact dermatitis, lichen planus and in evaluation of therapeutic efficacy, detecting of infestation like tinea, skabiyes, demodicosis and determining the level of bullae in bullous disease. Due to being noninvasive, RCM is preferred in cosmetology, in clinical research and practice for the evaluation of the effectiveness of cosmetic products and cosmetic procedures.
