Study Notes
Pathology CPC
- Pathology CPC is being discussed
- Two main symptoms are Flank pain and Haematuria
Case A: Male 65
- A 65-year-old male has left flank pain for 4 months
- The pain has no radiation
- The patient has no Sick Report (S/R) and was previously well
- On examination, there is a left sided abdominal mass
Differential Diagnosis of Flank Pain
- Renal Mass, benign, malignant or abscess
- Colonic Mass
- Adrenal Mass
- Ureteric Mass
- Splenomegaly
Laboratory Investigations
- Haemoglobin (Hb) is 17 g/dL
- C-reactive protein (CRP) is 40
- White cell count (WCC) is normal
Other Investigations
- The classification of investigations is on Moodle
- Other investigations include lab work, diagnostic imaging, and site specific investigations
- Ultrasound and CT scans of the abdomen are relevant
Ultrasound Results
- Ultrasound shows an 8cm mass on the left kidney
- The mass is described as iso- to hypoechoic and arises from the lower pole of the kidney
Differential Diagnosis
- Mass identified on the kidney could be a Tumor or an Abscess
- Tumors can be classified as either Benign or Malignant
- Malignant tumors can be Primary or Secondary
- Primary tumors include Carcinoma, Sarcoma and Lymphoma
- Secondary tumors include Carcinoma, Sarcoma, Melanoma, or Other
Renal Tumors
- A renal cell tumor is the most likely diagnosis in this age group
Further Investigations
- CT scans or Angiography are two further investigations
CT Scan
- A hypodense mass is visible
Biopsy Considerations
- A biopsy is usually unnecessary if CT features are pathognomonic
- Biopsies may be done in a small number of instances if the patient has a solitary kidney or is suitable for partial Nephrectomy
Differential Dx Renal Mass
- Differential diagnoses for a renal mass include renal cell carcinoma originating from kidney tubules or urothelium in the renal pelvis, lymphoma (B or T cell), sarcoma & metastasis
- Benign tumors include Angiomyolipomas associated with Tuberous Sclerosis, Oncocytoma, and Adenoma
Types of Renal Parenchyma Carcinoma
- Types of renal parenchyma Carcinoma include Clear cell, Papillary, Collecting duct, Chromosomal associated, and Chromophobe; clear cell is the most common
Aetiology of Renal Cell Carcinoma
- Genetic conditions like Von Hippel Lindau Syndrome, chromosomal translocations, Polycystic Disease, cystic disease related to dialysis, and smoking can contribute to the development of renal cell carcinoma
- More recently numerous other translocations identified
Treatment of Renal Parenchyma Cell Carcinoma
- Treatment options are Nephrectomy and, in some cases, Chemotherapy
Other Types of Carcinoma
- Urothelial carcinoma arises from the renal pelvis and is a more recent name for transitional cell Ca
- Prognosis relies on Stage, Grade and Type
Prognosis for Renal Carcinoma
- When confined to the kidney is 70% 5-year survival
- If the renal vein is involved is 15% 5-year survival
Paraneoplastic Effects in Renal Carcinoma
- Paraneoplastic effects sometimes seen in renal carcinoma are Polycythaemia, hypercalcaemia, hypertension, and Pyrexia of Unknown Origin (P.U.O.)
Summary
- Presentation, aetiology, prognosis and management of renal carcinoma
Case B: Male 56
- Overview of Haematuria
- A 56 year old male presents with Haematuria on 2 occasions and is otherwise considered well
Differential of Haematuria
- The differential of haematuria can be broken down into 3 categories; Renal, Post renal or General/systemic.
Renal Causes of Haematuria
- Renal causes of Haematuria include Tumor – Benign/Malignant, Glomerulonephritis, Calculi, Pyelonephritis, Trauma & Infarction with tissue necrosis e.g. emboli
- To think of renal causes Remember: glomeruli, tubules or pelvis of kidney
Non-Renal Causes of Haematuria
- Non-Renal Causes include Tumour in the Urinary Tract in the Bladder, Ureter, Urethra
- Specifically, Bladder causes of haematuria can be Urothelial, squamous cell or Adeno carcinoma, stones or an infection of Cystitis
- Anticoagulant Treatment can also cause Haematuria
Investigations of Haematuria
- The key investigations are the classification of investigations using the approach; Lab work, diagnostic imaging and organ & site specific testing
Investigations for Haematuria
- Ultrasound on the kidney
- Cystoscopy and Biopsy of bladder lesion if present
- IVP (intravenous pyelogram) uncommonly used
Cystoscopy Results
- A papillary tumour observed in the bladder
- Benign and malignant tumors, benign < malignant tumors and that overall malignant tumors are far more common
Bladder Carcinoma Types
- Urothelial Carcinoma (also called Transitional cell) , Squamous Ca with Schistosomiasis and calculi (metaplasia), Adenocarcinoma in urachal remnant, (Very rare) and colo/recto-vesical fistulae (also metaplasia) & Very occasional metastases
Other Bladder Neoplasms
- Sarcoma, Lymphoma, and Rare
PC of Bladder Carcinomas
- Symptoms and complications relating to Bladder Carcinomas include; Haematuria, Dysuria, Urgency, Hydro ureter due to obstruction of ureter - Hydronephrosis – due to obstruction of renal pelvis & Ureteric outflow obstruction
Bladder Carcinoma Prognosis
- Type, Grade & Stage are factors
- T refers to level of invasion through the bladder
Management of Urothelial/TCC Bladder
- Excision of Ca if early or Radical cystectomy for muscle invasive carcinoma or Treatment of Carcinoma in Situ - BCG
Aetiology of Bladder Cancer
- Smoking, Aniline Dye, Stones, Chronic inflammation, Schistosomiasis
Haematuria
- Several causes
- Could be from Kidney, Bladder, Ureter or Urethra
- These need to be imaged to find the cause
- Anticoagulation therapies eg. Warfarin and Heparin
Case C: Male 43
- A 43 year old male who was previously well presents with severe colicky left loin pain over the last 2/7, which was also of very sudden onset & extremely severe
Differentials
- Renal Colic is far most likely, GIT obstruction or maybe related to Gallstone colic
Single Test to Distinguish
- Carrying out a Urinalysis for blood during the routine checks and examinations is key when GP Surgery, Bedside or in the department OPD
Types of Urinary Stones
- Calcium Oxalate 80%
- Triple (Staghorn, MG, Ammonium, 15% Phosphate)
- Uric Acid
- Cystinuria / Oxalosis
Urinary Stones Causes
- In Calcium/Oxalate Stones which can cause Hypercalcaemia e.g. increased PTH leading to a defect in tubular re-absorption of calcium which is generally common
- In Triple stones it's With UTI's due to Proteus breaking down urea and resulting Alkaline urine causing the precipitation of salts
- Uric Acid Stones can feature Hyperuricaemia
Other Causes of Renal Colic
- Tumour obstructing and or a Blood clot in ureter – trauma or glomerular causes of haematuria – rare
Complications of Urinary Stones
- Obstructed ureter resulting Hydro ureter, Hydronephrosis and Pyelonephritis
- Stricture of the Ureter and Recurrent stones can cause pyelonephritis
Learning Outcomes
- Summarise the Clinical and the pathological features of renal cell carcinoma, listing the differentials and explaining prognosis with grade and stage
- Classifying renal calculi
