Actinic keratosis (AK) and cutaneous squamous cell carcinoma (cSCC) show similar aberrant methylation patterns. a Principal component analysis of 12 healthy, 16 AK, and 18 cSCC epidermis samples using all 850k CpG probes. b Scatter plots comparing the epidermis methylomes of healthy and AK samples (left panel), and healthy and cSCC samples (right panel). Differentially (P < 0.05, F-test) methylated probes are shown in blue. c Scatter plot comparing the epidermis methylomes of AK and cSCC samples. No significantly (P < 0.05, F-test) differentially methylated probes were detected
