Laser ablation is a promising approach for minimally invasive removal of superficial and early nodular basal cell carcinomas (BCCs)(Smucler et al., 2008, 2012). Skin can be removed in μm-thin layers in a well-controlled manner, increasing preservation of the surrounding normal tissue. However, tissue is vaporized such that there is none available for immediate histopathological confirmation. The efficacy tends to be variable and recurrence rate (8.25%) low (Smucler et al., 2008), compared to that reported for Mohs surgery (2.1–3.5%)(Chren et al. 2011, 2013), excision (3.5–4.2%) and electrodessication and curettage (1.6–4.9%). Thus, the implementation of laser ablation for BCCs in a clinical setting is still limited.A high-resolution nuclear-level optical imaging approach such as reflectance confocal microscopy (RCM)(Nori et al 2004, Guitera et al 2012) may guide laser ablation by detecting the presence or clearance of residual BCCs directly on the patient, to provide immediate histopathology-like feedback to improve the efficacy. Preliminary studies in human skin ex vivo with acetic acid for nuclear contrast (Sierra et al., 2013) and in vivo with aluminum chloride (Chen et al., 2014) revealed feasibility of imaging in post-ablated tissue. However, the imaging was of variable quality. Ablation was performed with a pulsed Erbium-doped Yttrium Aluminum Garnet (Er: YAG) laser, with pulse duration of~ 250 μsec that produces an underlying zone of thermal coagulation of~ 20 μm (Hohenleutner et al., 1997).
