Background: The accurate diagnosis of facial pigmented lesions is crucial due to their potential for malignancy and significant cosmetic concerns. This study aims to evaluate the effectiveness of line-field confocal optical coherence tomography (LC-OCT) in the morphological assessment of facial pigmented lesions and its correlation with reflectance confocal microscopy (RCM), thereby enhancing diagnostic accuracy and management strategies. Methods: Adult patients with clinically equivocal facial and scalp pigmented lesions were prospectively assessed using LC-OCT and RCM. Lesions included seborrheic keratosis, lichen-planus like keratosis, pigmented actinic keratosis, pigmented compound nevus, lentigo maligna, and invasive melanoma, with solar lentigo as a comparative entity. Images were analyzed for morphologic criteria and diagnostic performance, correlating LC-OCT findings with RCM and histopathological outcomes where applicable. Results: LC-OCT demonstrated high-resolution, tridimensional images that closely correlated with RCM findings, providing valuable insights into the micro-architectural and cytological aspects of lesions. For instance, solar lentigo revealed a regular honeycomb pattern and elongated rete ridges on both LC-OCT and RCM, while lentigo maligna and invasive melanoma presented atypical dendritic cells in the epidermis with follicular involvement. LC-OCT's vertical and tridimensional imaging capabilities offered enhanced visualization of the lesions' architecture and depth, providing easily-recognizable histopathology-like features. Conclusions: LC-OCT, with its ability to generate high-resolution, tridimensional images, complements RCM in the assessment of facial pigmented lesions, potentially offering enhanced diagnostic accuracy and potential for better management decisions. The technology's depth penetration and visualization capabilities highlight its value in dermatological practice, particularly for lesions where detailed architectural analysis is essential. This study underscores the utility of LC-OCT in the evolving landscape of dermatological imaging, warranting further research to establish its role in clinical practice.
