Fig. 6: Melanoma with adjacent lymphocytic inflammation from the IHC-test set.

a Hematoxylin and eosin (H&E) stains, along with corresponding b SOX10 immunohistochemistry (IHC) performed on the same tissue layer. c SOX10 virtual immunohistochemistry (vIHC) was performed using the H&E image as an input. Lymphocytes that were erroneously labeled as SOX10-positive by the vIHC are shown (white arrows). Notably, artifacts that will be found in slides used for clinical care, such as dotting marks, do not appear to have a significant adverse effect on the neural network in this case.
