Screening cancer in excision margins may be done with confocal microscopy to save time and cost over the gold standard histopathology (H&E). However, diagnostic accuracy requires sufficient contrast. Reflectance mode enables detection of large (>500um) nodular tumors. Enhanced nuclear contrast with acridine orange fluorescence mode additionally enables detection of tiny (<50um) basal cell carcinomas. Here, we present a novel combination of three modes to detect squamous cell carcinoma (SCC). Accurate screening of SCC requires eosin fluorescence, reflectance and acridine orange fluorescence to enable contrast for cytoplasm, collagen and nuclei respectively. Combining these signals replicates H&E for rapid clinical translation.
