Q: Which of the following is NOT correct for ‘strawberry gall bladder’?

It is a malignant condition of gall bladder. ***It is a malignant condition of gall bladder*** - **Strawberry gallbladder**, also known as **cholesterolosis**, is a **benign** condition where cholesterol esters accumulate in the macrophages within the lamina propria of the gallbladder wall. - It is **not cancerous** and does not lead to malignancy. *It may be associated with cholesterol Stones* - **Cholesterolosis** is often associated with a higher incidence of **cholesterol gallstones (cholelithiasis)**, as both conditions involve abnormal cholesterol metabolism [1]. - The accumulation of cholesterol in the gallbladder wall can sometimes precede or coincide with the formation of cholesterol stones within the lumen [1]. *Simple cholecystectomy is the treatment of choice* - For symptomatic **cholesterolosis**, especially when associated with pain or recurrent biliary colic, **cholecystectomy** (surgical removal of the gallbladder) is the standard and effective treatment. - Asymptomatic cases generally do not require treatment. *It has submucous aggregation of cholesterol crystals* - The characteristic appearance of **"strawberry gallbladder"** is due to the macroscopic visualization of yellow, lipid-laden macrophages aggregated within the **lamina propria** (a layer beneath the mucous membrane), appearing as tiny yellow flecks against a red mucosal background. - These aggregates contain **cholesterol esters**, which can crystallize. **References:** [1] Kumar V, Abbas AK, et al..

Q: All the following are features of Polycystic disease of kidneys EXCEPT:

Erythrocytosis. ***Erythrocytosis*** - While other renal conditions like **renal cell carcinoma** can cause erythrocytosis due to increased **erythropoietin** production, it is generally **not a typical feature** of Polycystic Kidney Disease (PKD). - Patients with PKD usually have **normal or even low erythropoietin levels** despite compromised kidney function, and anemia is more common, particularly as **renal failure progresses**. *Renal failure* - **Progressive cyst growth** leads to replacement of normal kidney parenchyma, inevitably culminating in **end-stage renal disease** [1] in the majority of patients. - This is a hallmark feature, often necessitating **dialysis or transplant** later in life for individuals with autosomal dominant polycystic kidney disease (ADPKD) [2]. *Haematuria* - **Gross or microscopic hematuria** is a common symptom in PKD, often resulting from **cyst rupture** [1], bleeding into a cyst, or the passage of a calculus due to urinary stasis. - It can be a presenting symptom and can cause significant pain and anxiety for patients. *Hypertension* - **Hypertension** is an early and frequent complication of PKD, often preceding any significant decline in glomerular filtration rate. - It is primarily caused by activation of the **renin-angiotensin-aldosterone system (RAAS)** [3] due to arterial compression and ischemia from expanding cysts. **References:** [1] Kumar V, Abbas AK, et al..

Q: Which of the following factors is labelled as cytokine in the pathogenesis of Systemic Inflammatory Response Syndrome (SIRS)?

Tumor necrosis factor. ***Tumor necrosis factor*** - **Tumor necrosis factor (TNF-α)** is a prominent pro-inflammatory cytokine and a key mediator in the pathogenesis of **Systemic Inflammatory Response Syndrome (SIRS)** [1]. - It plays a crucial role in initiating and amplifying the inflammatory cascade, leading to systemic effects like fever, increased vascular permeability, and tissue damage [1]. *Leukotrienes* - **Leukotrienes** are lipid mediators derived from arachidonic acid, involved in inflammation and allergic reactions [1]. - They are not classified as **cytokines**, which are protein signaling molecules [1]. *Nitric oxide* - **Nitric oxide (NO)** is a gaseous signaling molecule with various physiological roles, including vasodilation and neurotransmission. - While it contributes to the pathophysiology of SIRS, particularly in regulating vascular tone, it is not a **cytokine**. *Complements* - **Complements** are a system of plasma proteins that are part of the innate immune response, helping to clear pathogens [1]. - They participate in inflammation but are distinct from **cytokines**, which are regulatory proteins [1]. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Inflammation and Repair, pp. 93-101. [Practice more Pathology PYQs on OnCourse]

Q: Which of the following conditions of the endometrium is associated with a significantly increased risk of development of cancer?

Complex hyperplasia with atypia. ***Complex hyperplasia with atypia*** - This condition carries the highest risk of progression to **endometrial carcinoma**, with approximately a 29% chance of concurrent or subsequent carcinoma [1], [2]. - The presence of **atypia** (abnormal cellular architecture and nuclear features) is the critical factor indicating a high malignant potential [1], [2]. *Complex hyperplasia* - While a form of endometrial hyperplasia, it lacks the **atypical cellular features** that significantly elevate the risk of malignancy [1]. - The risk of progression to endometrial carcinoma is much lower, around 3%, compared to atypical forms [1]. *Simple atypical hyperplasia* - This condition features **atypia** but with a less complex glandular architectural proliferation than complex atypical hyperplasia [2]. - Although it has a lower risk of malignancy than complex atypical hyperplasia (around 8%), it still has a significantly higher risk than non-atypical hyperplasias. *Simple hyperplasia* - This is the **least severe** form of endometrial hyperplasia, characterized by glandular and stromal proliferation without architectural complexity or cellular atypia [1]. - The risk of progression to endometrial carcinoma is very low, approximately 1%, making it far less concerning than atypical forms [1]. **References:** [1] Cross SS.
