Full-field optical coherence tomography (a and b) and corresponding H&E images of (c and d) of benign kidney tumors. (a) Angiomyolipoma showing signal void polygonal adipocytes (arrows) and bright connective tissue from collagen (arrowhead). (b) Cystic nephroma showing large signal void cyst (*) lined by single-layered epithelium with dull gray signal (arrow and inset with arrowhead) embedded in thick collagenous tissue (bright signal; arrowhead). Full-field optical coherence tomography; scale bars (a) = 0.25 mm, (b) = 0.5 mm. Inset 2 × zoom of images B. H&E (c and d); total magnifications = ×200.
