Which of these are statements are NOT true with regards to Wilms tumour?
Nephrogenic rests are identified in 100% of bilateral Wilms tumour
Children with WAGR syndrome have a 33% chance of developing Wilms tumour
Pulmonary metastases are uncommon at the time of diagnosis
In 10% of cases, there are bilateral or multicentric tumours at the time of diagnosis
The peak age for diagnosis of Wilms tumour is 2-5 years of age
Answer: Pulmonary metastases are uncommon at the time of diagnosis (FALSE)
FROM ROBBINS
- Most children with Wilms tumors present with a large abdominal mass. Hematuria, pain in the abdomen after some traumatic incident, intestinal obstruction, and appearance of hypertension are other patterns of presentation. in a considerable number of these patients, pulmonary metastases are present at the time of primary diagnosis.
- Nephrogenic rests are putative precursor lesions of Wills tumors, and are seen in the renal parenchyma adjacent to approximately 25-40% of unilateral tumors; this frequency rises to nearly 100% in cases of bilateral Wilms tutors.
- The risk of Wilms tumor is increased with a least three recognisable groups of congenital malformations associated with distinct chromosomal loci; WAGR syndrome, Denys-Drash syndrome, and Beckwith-Wiedemann syndrome
- WAGR syndrome is characterised by Wilms tumor, aniridia, genital anomalies, and mental retardation. The lifetime risk of developing Wilms tumor is approximately 33%.
- Grossly, Wilms tumor tends to present as a large, solitary, well-circumscribed mass, although 10% are either bilateral or multi centric at the time of diagnosis.
- IN approximately 5-10% of Wilms tumors involve both kidneys, either simultaneously (synchronous) or one after the other (metachronous).
- The peak incidence for Wilms tumor is between 2 and 5 years of age, and 95% occur before the age of 10 years old.
- Approximately 5% of tumors reveal anaplasia. The presecence of anaplasia correlates with the presence of TP53 mutations, and the emergence of resistance to chemotherapy.
Which of the following is MOST likely to be associated with Rheumatoid arthritis?
HLA B27 antigen
IgM anti IgG antibodies
Anti - DNase B
Urate crystals and neutrophils in synovial fluid
Antibodies to double stranded DNA
Answer: IgM anti IgG antibodies.
FROM ROBBINS
- 80% of patient has serum IgM or IgA autoantibodies that bind to the Fc portions of their own IgG. These autoantibodies are call Rheumatoid Factor.
- 50% of the risk developing RA is related to inherited genetic susceptibility. Specific HLA-DRB1 alleles are linked to RA. (HLA-DRB1 is the most common allele of HLA-DR4).
- The synovial of RA contains germinal centres with secondary follicles and plasma cells which produce antibodies. Many of the autoantibodies produced are specific for citrullinated peptides (CCPs).
FROM RADIOPAEDIA
- RF is a traditional marker but is non-specific, associated with several autoimmune and chronic infectious diseases
- Anti-CCP/anti-citrullinated plasma antibody (ACPA) is more than 80% sensitive and more than 95% specific.

Hypoparathyroidism can be caused by all of the following except:
Congenital parathyroid absence
Autoimmune mediated
Parathyroid removal
Chronic hypocalcaemia
End organ resistance to parathyroid hormone (PTH)
Official answer: chronic hypocalcaemia. Round one goes to Saj.
CCF - End organ resistance to parathyroid hormone (PTH)
as this is describes pseudohypothyroidism and is ass w HyperPTH.
Chronic hypocalcaemia - is also wrong (Hyper PTH like in secodary hyperpara)).
^SCS agree; two technically incorrect answers. The body is essentially running as hypoparathyroid in pseudoHPT so i would go with chronic hypocalcaemia if i had a gun to my head….
Also hypomagnesaemia can do it.
Good discussions all around. Pity about the ambiguity in the question.
Disagree - Chronic hypocalcaemia will give your HYPERparathyroidism.
End organ resistance to parathyroid hormone (PTH) - yes this is pseudo but still results in hypoparathyroidism which is what the question is asking]
^ Disagree - Psudo is end organ resistance to PTH, therefore to try and compensate the PTH is HIGH (feedback loops).
*** see robins pg 1105 (9th edition) PTH levels can be normal in pseudospeudphypo
**WJI - a lot of argument here. I think it is important to note that the question asks for causes of hypoparathyroidism which is the clinical syndrome. It does not ask for causes of raised parathyroid hormone. In end organ resistance the patient may have a raised PTH (irrelevant) but will have the syndrome of hypoparathyroidism (or pseudohypoparathyroidism). Agree with chronic hypocalcaemia as this results in hyperparathyroidism.
**Pathlads: we concur.

Answer: Centre of nodule consists of an read of coagulative necrosis (NOT TRUE)
FROM ROBBINS
- Rheumatoid nodules: necrotising granulomas with a central zone of fibrinoid necrosis surrounded by a prominent rm of activated macrophages and numerous lymphocytes and plasma cells.
- Cutaneous rheumatoid nodules are the most common. They occur in 25% of affected individuals, usually those with severe disease. Less commonly, the form in the lungs, spleen, pericardium, myocardium, heart valves, and aorta.
FROM RADIOPAEDIA/STATDX

Post menopausal PV bleeding and endometrial hyperplasia is associated with which of the following ovarian neoplasms?
Granulosa cell tumour
Serous cystadenocarcinoma
Teratoma
Krukenberg tumour
Dysgerminoma
Answer: Granulosa cell tumour
FROM ROBBINS
- Granulosa cell tumors are of clinical importance for two reasons: (1) they may elaborate large amounts of extrogen, and (2) they may behave like low-grade malignancies.
- In prepubertal girls (juvenile granulosa cell tumors) they may produce precocious sexual development.
- In adult women, they may be associated with proliferative breast disease, endometrial hyperplasia, and endometrial carcinoma, which eventually develops in 10-15% of women.
- Occasionally, granulos cell tumors produce androgens, masculizing the patient.,
- Histologically, Call-Exner Bodies are seen.
OTHER (From Robbins)
- Serous cystadenocarcinoma is a primary ovarian neoplasms arising from mullerian epithelium.
- Krukenberg tumor is a classic metastatic gastrointestinal carcinoma involving the ovaries, characterised by bilateral metastases composed of mucin-producing signet-ring cancer cells, most often of gastric origin.
- Teratomas, often referred to as dermoid cysts, are tumors of germ cell origin can can be divided into three categories. 1) mature (benign), 2) immatures (malignant), 3) monodermal or highly specialised.
- Dysgerminoma is the ovarian counterpart of testicular seminoma. Most of these tumors have no endocrine function. A few produce elevated levels of chorionic gonadotropin. They express OCT-3, OCT4, and NANOG transcription factors. They also express receptor tyrosine kinase KIT, with 1/3 having activating mutations in the KIT gene.

Ventricular aneurysm
Myocardial (pump) failure
Myocardial rupture
Arrhythmia
Mural thrombosis
Answer: Myocardial rupture
FROM ROBBINS
- Ventricular aneurysms are a late complication of large transmural infarcts that experience early expansion.
- Contractile dysfunction: Severe “pump failure” occurs in 10-15% of patients following acute MI, generally with large infarcts involving more than 40% of the left ventricle. Has a nearly 70% mortality rate. occurs within 4 hours.
- Myocardial Rupture: Occurs most frequently 2-4 days after MI when coagulative necrosis, neutrophilic infiltration, and lysis of the myocardial connective tissue have appreciable weakened the infarct myocardium. Rupture of the free wall (anterolateral wall at the mid-ventricular level) is the most common site.
- Arrhythmias: within 4-24 hours of MI.

Biopsy from this area would have most likely revealed which of the following?
Sessile serrated adenoma
Peutz-jeghers polyp
Tubular Adenoma
Hyperplastic polyp
Inflammatory polyp
Answer: Sessile serrated adenoma
FROM ROBBINS
- Sessile serrated adenomas are more commonly found in the right colon. It is indistinguishable from hyperplastic polyps
- Hyperplastic polys are benign epithelial proliferations that are typically discovered in the 6th-7th decades of life. They are most commonly found in the left colon and a smooth, nodular protrusions of the mucosa, often on the crests of mucosal folds. Their chief significance is that they must be distinguished from sessile serrated adenomas.
- Inflammatory polyps are most commonly found on the anterior rectal wall.
- Tubular adenomas are small, pedunculate polyps.
- Peutz-Jeghers syndrome is a rare autosomal dominant syndrome which presents at a median age of 11 years old with multiple GI hamartomatous polyps and mucocutaneous hyperpigmentation.
