Background: Renal oncocytoma, chromophobe RCC, and conventional RCC (granular cell type) have different prognosis. The differentiation between them sometimes is difficult and may cause a diagnostic dilemma.
Aim of Study: To reveal the better immunohistochemical diagnostic markers for differentiation between Chromophobe Renal Cell Carcinoma (ChRCC), Clear Cell Renal Cell Carcinoma (CCRCC), and oncocytoma.
Material and Methods: We reviewed one hundred and fifty cases of renal cell carcinoma: ChRCC (100 case), CCRCC (25 cases) and RO (25 cases). We carried out comprehensive immunohistochemical profiling using Hales Colloidal Iron stain (HCI), and 6 markers: Vimentin, CK7, CD10, CD117. EpCAM, and S100.
Results: Our results demonstrated a statistically significant difference in the expression of Hales colloidal iron among the studied renal tumors (p-value |
