Abstract

Nonmelanoma skin cancers (NSMC) are among the most common malignancies in the US today. Mohs micrograph surgery (MMS) is the gold standard for most NSMC. However, MMS is time-consuming as it employs frozen section analysis (FSA) for intraoperative assessment. Each FSA can require up to 60 minutes per excision. Using photoacoustic remote sensing (PARS™) we demonstrate first results of imaging tissue morphology on human skin with a non-contact reflection-mode method, enabling rapid label-free pathological assessment. These images are validated against toluidine blue stained sections. The authors believe the proposed method represents a vital step towards an in-situ assessment of NSMC.
