Aim: Dermoscopic features of cutaneous squamous cell carcinoma (SCC) have been well described; however, there are a few studies focused on the dermoscopic aspect of lip SCC. In this study, we aimed to identify dermoscopic findings of lower lip SCC. Materials and Methods: The clinical and histopathologic features, dermoscopic images, and demographic data of the patients with histologically approved lip SCC were retrospectively evaluated. Results: A total of 10 lesions were enrolled in the study. Milky red structureless background (100%) and keratin scale (100%) were present in all the lesions. Blood spots on thick keratin scale were observed in eight lesions. Seven lesions showed white structureless areas. Two lesions exhibited ulceration and one of the lesions had structureless brown pigmentation. The most common vascular pattern observed was polymorphous vascular pattern (60%). Conclusion: White and milky red structureless areas, blood spots on thick keratin scale, and polymorphous vascular pattern are the main dermoscopic clues to lip SCC. The presence of these findings should direct the clinician to the possibility of SCC. The dermoscopic findings observed may also reflect histological grade of the lesion.
