PDD/PDT and histopathological results—soft tissue tumors. H9—dedifferentiated liposarcoma G2. PDD only. Fluorescence +. Arrow highlights areas with regressive changes in a specimen classified as regressive considering the entire sample. H24—dedifferentiated liposarcoma G2. PDT. Fluorescence ++. Arrow highlights areas with regressive changes in a specimen classified as regressive considering the entire sample. J50—pigmented villonodular synovitis/tenosynovial giant cell tumor. PDD only. Fluorescence +. Arrow highlights vital tumor areas in a specimen classified as viable considering the entire sample. J20—UPS G2. PDD only. Fluorescence ++. As an example of intralesional heterogeneity, arrow highlights areas with regressive changes in a specimen classified as viable considering the entire sample. J8—UPS G2. PDT. Fluorescence ++. Arrow highlights areas with regressive changes in a specimen classified as partially regressive considering the entire sample. L55—myxofibrosarcoma G3. PDD only. Fluorescence ++. As an example of intralesional heterogeneity, arrow highlights areas with residual vital tumor in a specimen classified as regressive considering the entire sample
