Screening of skin cancer by teledermatology (TD) has improved the early detection of skin cancer by enhancing access to skin cancer clinics.
We sought to analyze how TD-based skin cancer screening has changed the frequency of consultations for benign lesions.
A cross-sectional study including teleconsultations received during a 7-year period was conducted to analyze and compare the trendlines of each lesion type over the study period. Trendlines were analyzed using a linear regression model with the R-squared (R ) test for goodness of fit.
A total of 34,553 teleconsultations were included in the study. Seborrheic keratoses, followed by benign melanocytic lesions, were the most frequent lesions diagnosed. The pick-up rate for malignant lesions was 1:8.6 teleconsultations. Seborrheic keratoses and precancerous lesions showed a positive trendline with good fit to the linear model (R = 0.8 and R = 0.8, respectively). Tis-T1 malignant melanoma (in situ melanoma or melanoma with a Breslow thickness <1 mm) showed an increasing trendline with moderate-to-low fit to the model (R = 0.4).
TD-based screening of skin cancer is associated with an increasing rate of consultations involving seborrheic keratoses, which can be considered a consequence of improved access to dermatologists resulting from TD implementation.
通过远程皮肤病学（TD）筛查皮肤癌，提高了对皮肤癌诊所的访问，从而改善了皮肤癌的早期检测。
我们旨在分析基于 TD 的皮肤癌筛查如何改变了良性病变的就诊频率。
进行了一项包括在 7 年内进行的远程咨询的横断面研究，以分析和比较研究期间每种病变类型的趋势线。使用 R 方（R ² ）检验拟合优度的线性回归模型分析趋势线。
共纳入 34553 例远程咨询。脂溢性角化病和良性黑素细胞病变是最常见的诊断病变。恶性病变的检出率为 1:8.6 次远程咨询。脂溢性角化病和癌前病变呈正趋势线，与线性模型拟合良好（R ² = 0.8 和 R ² = 0.8）。Tis-T1 期恶性黑色素瘤（原位黑色素瘤或 Breslow 厚度<1mm 的黑色素瘤）呈中度至低度拟合的上升趋势线（R ² = 0.4）。
基于 TD 的皮肤癌筛查与涉及脂溢性角化病的咨询率增加相关，这可以被认为是由于 TD 的实施提高了皮肤科医生的可及性而导致的结果。
