A kidney tumour (renal oncocytoma). (WC/Emmanuelm)
Kidney tumours - includes malignant kidney tumours (kidney cancer) and benign kidney tumours. Medical renal diseases are dealt with in the medical renal diseases article.
Pediatric kidney tumours are dealt with in the pediatric kidney tumours article.
Renal specimens
- Renal biopsy - usually for renal oncocytoma vs. renal cell carcinoma (RCC) or medical diseases - see medical kidney.
- Partial nephrectomy.
- Nephrectomy.
- Nephroureterectomy (includes ureter) - done for urothelial cell carcinoma (UCC) of the renal pelvis and ureteric UCC.
- Radical nephrectomy - includes Gerota's fascia.
- May include the adrenal gland.[1]
In excisions done for tumours, a comment should be made about kidney distant from the tumour. People with less renal mass, i.e. less kidney, are predisposed to focal segmental glomerulosclerosis (FSGS).
Anatomy
Layers (superficial to deep):
- Renal fascia (Gerota's fascia).
- Perinephric fat.
- Renal capsule.
- Renal parenchyma (cortex).
Sign out
Missed renal biopsy
KIDNEY (LESION), LEFT, CORE BIOPSY: - RENAL PARENCHYMA. - NEGATIVE FOR MASS LESION, SEE COMMENT. COMMENT: No mass lesion is apparent in the tissue sampled. A re-biopsy should be considered. Renal parenchyma: - Glomeruli: seven glomeruli sampled, no apparent glomerular pathology on the H&E sections. - Interstitium: interstitial fibrosis is not identified. - Tubules: no pathology is apparent. - Vessels: mild atherosclerosis, no hyalinization of arterioles apparent.

Renal cell carcinoma
Overview
General
- Relatively common form of cancer.
- Often abbreviated RCC.
- AKA hypernephroma.[7]
- RCC represents approx. 90% of malignancies in kidneys of adults.[8]
Origin
- Proximal renal tubule.
Clinical
- Classically described as a triad:[9]
- Hematuria (most common symptom).
- Abdominal mass.
- Flank pain.
- Frequently picked-up on imaging (incidentaloma) ~ 1/3 of cases.
Risk factors
- Smoking - most important.[8]
- Chemical exposures (arsenic, asbestos, cadmium, organic solvents, pesticides, fungal toxins).[8]
- Chronic renal failure.
- Male>female (~2:1).
- Hereditary - familial syndromes (see Hereditary RCC).
Subtypes of RCC
RCC (renal cell carcinoma) comes in different subtypes:[10]
- Clear cell carcinoma (70-80% of RCC) -- abbrev. CCRCC,
- Papillary renal cell carcinoma (10-15% of RCC) -- abbrev. PRCC,
- Chromophobe renal carcinoma (5% of RCC) -- abbrev. ChRCC,
- Collecting duct (Bellini duct) carcinoma (1% of RCC).
Notes:
- Subtype is an independent predictor of mortality - but adds very little to multivariate models with staging information.[11]
- CCRCC tends to be worse than ChRCC and PRCC, probably due to higher incidence of mets.[12]
- The exam answer (worst to best): clear cell RCC, papillary RCC, chromophobe RCC.
IHC - is it RCC?
- RCC Ma (+), CD10 (+) -- specific for RCC[13]
IHC - differentiation of types
- Clear cell RCC vs. papillary RCC:
- CK7 (-ve CCRCC), AMACR (+ve in PRCC).[14]
- Papillary RCC type 1 vs. papillary RCC type 2:
- ChRCC vs. oncocytoma (ONC):
- CK7 (ChRCC +ve membrane), CK20, CD15.[14]
- CK7 -- ChRCC 86% +ve vs. ONC 0% +ve.[16]
- CD15 -- ChRCC 11% +ve vs. ONC 57% +ve.[17]
- Hale's colloidal iron +ve in ChRCC, usually neg. in ONC.[18]
- PAX2 -- ChRCC (1/11) +ve vs. ONC (20/23) +ve.[19]
- Kidney-specific cadherin (Ksp-cadherin) -- ChRCC 97% +ve (distinctive membrane pattern) vs. ONC only 3% +ve.[20]
- ChRCC & renal oncocytoma vs. others:
- CD117 (ckit) +ve (100% membrane, ~75% cytoplasmic).[21]
- Clear cell RCC vs. chromophobe RCC:
- Hale's colloidal iron (+ve in ChRCC).[18]
- CK7 (cell membrane +ve in ChRCC).
Notes:
- One paper[22] describes CD10, parvalbumin, AMACR, CK7 and S100A1 as being useful.
- Another paper I came across:[23]
- c-kit (CD117) not useful for differentiating ONC and ChRCC.[19]
- E-cadherin not useful for differentiating ChRCC and ONC.[24]
RCC vs. Urothelial cell carcinoma
Main article: Urothelium
- Clinically/radiologically, it may not be possible to differentiate renal pelvis UCC and RCC if the tumour is large.
- Pathologically, this is not very difficult.
- On gross specimens, it is almost always obvious what one is dealing with:
Renal cell carcinoma with sarcomatoid differentiation
- AKA sarcomatoid renal cell carcinoma.
General
Features:[25]
- Not recognized as a distinct entity in 2004 WHO classification.[26]
- Tend to present at higher stage.
- Worse prognosis when adjusted for stage.
- Fuhrman grade 4 by definition.
Microscopic
Features:[25]
- Renal cell carcinoma.
- Sarcomatoid component:
- Fibrosarcoma - most common.
- Undifferentiated - common.
- Rhabdomyosarcoma - very rare.
Notes:
- In essence, any kidney tumour with spindle cells should make one think of this.[28]
- Rhabdoid change in renal cell carcinoma is probably analogous to sarcomatoid change.[29]
Images:
- Sarcomatoid change in RCC (webpathology.com).
- Sarcomatoid changes in CCRCC (ascopubs.org).[30]
- Sarcomatoid changes in RCC (scielo.br).[28]
Renal cell carcinoma with rhabdoid morphology
- AKA renal cell carcinoma with rhabdoid change.
Main article: Renal cell carcinoma with rhabdoid morphology
Hereditary renal cell carcinoma
The classics - which are all autosomal dominant:[10]
- Von Hippel-Lindau syndrome.
- VHL gene mutation.
- Clear cell RCC.
- Hereditary clear cell renal cell carcinoma.
- VHL gene mutation.
- Hereditary papillary renal cell carcinoma.
- MET proto-oncogene mutation.
- PaRCC type 1.[31]
- Hereditary leiomyomatosis and renal cell cancer:[31]
- FH (fumarate hydratase) gene mutation.[32]
- PaRCC type 2.
- Benign leiomyomas skin/uterus.
- Uterine leiomyosarcoma.
- Birt–Hogg–Dubé syndrome:[31]
- FLCN (folliculin) gene mutation.[33]
- Skin lesions (fibrofolliculoma, trichodiscoma, acrochordon).
- ChRCC most common, other types seen (e.g. oncocytoma).
- Variable penetrance (autosomal dominant).
Others:
- Hereditary papillary carcinoma (TFE3 related translocations).[34]
Notes:
- A total of ten hereditary renal cancer syndromes have been described. In eight of the ten the gene is known.[35]
Molecular
Recurrent molecular changes in RCC:
- Clear cell RCC:
- Loss of 3p - contains the VHL gene.
- Papillary RCC:
- Sporadic:
- Trisomy 7, 16, 17.
- Loss of Y.
- Familial:
- Trisomy 7 - contains MET gene.[36]
- Sporadic:
Renal cell carcinoma grading
General
There are two systems:
- Fuhrman grading:
- Older and more complicated.
- Based on nuclear size and shape, chromatin pattern and nucleolar size.[37]
- More complicated.
- ISUP grading:[38]
- Newer and less complicated.
- Mostly based on nucleolar size and to a much lesser degree on size and morphology
- Developed based on Fuhrman grading.
ISUP grading
Criteria:[38]
- Grade 1 - nucleoli absent/very small at 400x. §
- Grade 2 - nucleoli seen with 400x, but not at 100x. §§
- Grade 3 - nucleoli seen at 100x, i.e. with the 10x objective.
- Grade 4 - extreme nuclear pleomorphism (esp. nuclear enlargement) or sarcomatoid differentiation (spindle cells[28] or rhabdoid cells).
Cavets:[38]
- Higher grade component trumps lower grade component.
- No agreed upon minimum quantity of high grade component for upgrading.
- 37% use 1 field of view with the x10 objective. †
- 41% use 1 field of view with the x40 objective. ‡
- No agreed upon minimum quantity of high grade component for upgrading.
- Grading system not used for chromophobe RCC.
- The experience with the Fuhrman grading system showed it is not prognostic for chromophobe RCC.[39]
Notes:
- † Suffers from IPFitis.
- ‡ Suffers from HPFitis.
- § Some describe Grade 1 nuclei as lymphocyte-like.[citation needed]
- §§ Some suggest the following relationship between grading/nucleoli:[citation needed]
- Grade 1 = nucleoli seen at 400x.
- Grade 2 = nucleoli seen at 200x.
- Grade 3 = nucleoli seen at 100x.
