Figure 5: (a and b) Loupe image of metastatic lesions in the lymph node and photoacoustic imaging reconstructed into a plane with a wavelength of 690 nm. The photoacoustic signal was also obtained from the site of lymphocyte accumulation without melanin (open arrowheads). It was speculated that the effect was mainly related to hematoxylin bound to the nuclei of lymphocytes according to the results of histopathological analysis
