Overview
A needle biopsy should always be performed when the finding of a renal mass is detected on imaging.
Needle Biopsy
Needle biopsy should always be performed when the finding of a renal mass is detected on imaging. CT or MRI guided needle biopsy distinguishes between different subgroups of renal cell carcinoma and identifies management: active surveillance, surgery, or medical therapy.[1] The sensitivity and specificity of needle biopsy are very high. The rate of biopsy-related complications, including biopsy-associated seeding, is considered very low.[1]
| Type | Characteristic Features |
| Conventional (Clear Cell) | *Nests of tumor cells that are compacted near each other *Clear cytoplasm *Delicate vasculature that separates the cytoplasm *Varying architectural patterns, such as solid, alveolar, or acinar |
| Papillary | *Papillae, tubulopapillae, and tubules that are present in differing percentages *Type I generally has papillae lined with only 1 layer of cancer cells, pale cytoplasm, and small oval nuclei *Type II generally are more heterogeneous tumors that have pseudostratification with large, spherical nuclei and distinct nucleoli |
| Chromophobe | *Large polygonal cells *Finely reticulated cytoplasm that may be eosinophilic *Distinct cell borders *Atypical nuclei with perinuclear halo |
