When the dermoscopy of squamous cell carcinoma and its precursors we differentiate among keratin-related, vascular, and pigment-related criteria. Non-pigmented actinic keratoses are characterized by the "strawberry pattern". Pigmented actinic keratosis shows a significant dermatoscopic overlap with lentigo maligna, but the presence of pigmented scales, erythema, and prominent follicles favors its diagnosis. Bowen's disease is characterized by clustered glomerular vessels, white-yellowish scales, and brown or grey dots arranged in lines in its pigmented variant. Finally, dermoscopy allows us to detect invasive squamous cell carcinoma in its early stages and differentiate it from its precursors. Furthermore, its presentation may vary depending on the degree of differentiation, with keratin-associated criteria predominating in well-differentiated tumors, while an atypical vascular pattern will predominate in poorly differentiated tumors.
当对鳞状细胞癌及其前体进行皮肤镜检查时，我们需要区分与角蛋白相关、血管相关和色素相关的标准。非色素性光化性角化病的特征是“草莓状图案”。色素性光化性角化病与恶性雀斑样痣在皮肤镜下有明显的重叠，但存在色素性鳞屑、红斑和明显的毛囊有利于其诊断。鲍恩病的特征是簇状肾小球血管、黄白色鳞屑，以及色素型中呈线状排列的棕色或灰色斑点。最后，皮肤镜检查可以帮助我们在早期发现侵袭性鳞状细胞癌，并将其与前体区分开来。此外，其表现可能因分化程度而异，角化相关标准在分化良好的肿瘤中占主导地位，而在分化不良的肿瘤中，非典型的血管模式将占主导地位。
