We present a multiphoton microscopy approach with clearing optimized for pathology evaluation producing image quality comparable to traditional histology. Use of benzyl alcohol/benzyl benzoate with 4',6-diamidino-2-phenylindole and eosin in an optimized imaging setup results in optical sections nearly indistinguishable from traditionally-cut sections. Application to human renal tissue demonstrates diagnostic-level image quality can be maintained through 1 millimeter of tissue. Three dimensional perspectives reveal changes of glomerular capsule cells not evident on single sections. Collagen-derived second harmonic generation can be visualized through entire biopsies. Multiphoton microscopy with clearing has potential for increasing the yield of histologic evaluation of biopsy specimens.
