case_images: CCPRCC. (A and B) Cystic tumour with branching papillae (haematoxylin and eosin [H&E] stain, 10x). (C and D) Cuboidal/columnar tumour cells exhibiting clear cytoplasm (H&E stain, 20x). (E) Low-grade linearly arranged nuclei, aligned away from basement membrane (H&E stain, 40x). (F-I) The tumour cells were diffusely positive for PAX8 (F), CK7 (G), and beta-catenin (H) and negative for CD10 (I) (20x)

case_images: Microscopically, all three cases showed branching papillae lined by cuboidal/columnar tumour cells with clear cytoplasm and a linear array of low-grade nuclei placed away from the basement membrane [Figure 1A-E]. Tumour cells were diffusely positive for PAX8, CK7, and beta-catenin; and negative for CD10 [Figure 1F-I].
