Liver and Biliary Pathology Practice Questions

Q: A 30-year-old shepherd presents with painless hepatomegaly. Peripheral blood work shows eosinophilia. The histopathological slide of surgically removed cyst shows a marking X. This denotes:

Hydatid sand. ***Hydatid sand*** - The clinical presentation of painless hepatomegaly in a shepherd with eosinophilia is highly suggestive of **hydatid cyst (Echinococcosis)**. - **Hydatid sand** refers to the granular material found in hydatid cysts, consisting of **protoscolices**, hooklets, and calcareous corpuscles, which are diagnostic on histopathology [1]. *Blood capsule* - This term is not typically used in the context of hydatid cysts or their histopathology. - It does not describe a specific component of a hydatid cyst. *Endocyst* - The **endocyst** (or germinal layer) is the inner, nucleated layer of the hydatid cyst that produces the protoscolices and hydatid fluid [1]. - While part of the cyst, it is a layer, not the granular material referred to as "marking X" in the context of diagnostic findings. *Ectocyst* - The **ectocyst** (or laminated layer) is the acellular, chitinous, and elastic outer layer of the hydatid cyst, surrounding the endocyst [1]. - It is a structural component of the cyst wall, not the diagnostic granular material found within the cyst fluid. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Infectious Diseases, pp. 404-405.

Q: A 20-year-old college student presents with 7 day history of nausea and feeling feverish. He has tenderness in right upper quadrant and admits to high risk sexual behavior. The liver biopsy marking $X$ shows:

Councilman body. ***Councilman body*** - The clinical presentation (nausea, fever, RUQ tenderness, high-risk sexual behavior) is highly suggestive of **acute viral hepatitis**, likely **Hepatitis B** given the risk factors. - **Councilman bodies** (also known as **apoptotic bodies**) are characteristic findings in acute viral hepatitis, representing **apoptotic hepatocytes** [1]. *Mallory hyaline body* - **Mallory bodies** (or **Mallory-Denk bodies**) are typically seen in **alcoholic hepatitis** and other forms of **chronic liver injury**, not acute viral hepatitis [2]. - They are composed of **intermediate filaments** (cytokeratins) and other proteins, indicating hepatocyte damage. *Russell body* - **Russell bodies** are **eosinophilic inclusions** found within the cytoplasm of **plasma cells**, representing **accumulations of immunoglobulins**. - They are associated with conditions involving plasma cell proliferation, such as **multiple myeloma**, and are not a feature of acute viral hepatitis. *Normal kupffer cell* - **Kupffer cells** are **resident macrophages** of the liver and are normally present in the sinusoids. - While they play a role in inflammation, their presence alone as "normal" does not represent the specific pathological change expected in acute viral hepatitis, which is hepatocyte apoptosis [1]. **References:** [1] Cross SS.

Common Clinical Problems From Liver And Biliary System Disease, pp. 389-390.

Q: A 54-year-old chronic alcoholic died due to a liver disease. His pathological specimen is provided in the image below. The most likely diagnosis is:

Cirrhosis. ***Cirrhosis*** - The image of the liver from a chronic alcoholic, showing a **nodular, shrunken appearance**, is highly characteristic of **cirrhosis** [1][2]. - **Cirrhosis** is the end-stage of chronic liver disease, marked by widespread **fibrosis** and the formation of **regenerative nodules**, leading to impaired liver function [1][2]. *Focal nodular hyperplasia* - This is a **benign liver lesion** typically characterized by a **central stellate scar** and radiating fibrous septa, which is not consistent with the generalized nodularity seen in the image of a cirrhotic liver. - It usually occurs in otherwise healthy livers and is not directly linked to chronic alcoholism or diffuse liver failure. *Alcoholic fatty liver* - **Alcoholic fatty liver** (steatosis) is an early, usually reversible, stage of alcoholic liver disease characterized by **lipid accumulation** in hepatocytes, making the liver enlarged and greasy, but not typically shrunken and nodular [3]. - While it can progress to more severe forms, the image depicts the advanced, fibrotic changes of cirrhosis rather than simple steatosis [3]. *Hemangioma* - A **hemangioma** is a **benign vascular tumor** of the liver, appearing as a well-circumscribed, often dark red, spongy mass composed of blood vessels. - It presents as a focal lesion and does not cause the diffuse, nodular, and shrunken appearance of the entire liver seen in the image, which is indicative of widespread parenchymal damage. **References:** [1] Kumar V, Abbas AK, et al..

Q: A 14-year-old male child presents with right upper quadrant pain, his pathological presentation is given in the image. Which one of the following statements is false?

This is radio-opaque in nature. ***This is radio-opaque in nature*** - **Pigment stones**, specifically **black pigment stones**, are typically **radio-lucent** or only faintly radio-opaque, making this statement false [1]. - Their radio-opacity is due to calcium content, but it's usually insufficient to be clearly visible on plain X-rays. *Composed of calcium bilirubinate* - **Black pigment stones** are primarily composed of **calcium bilirubinate** and small amounts of calcium phosphate and calcium carbonate [2][3]. - They form when there is an excess of unconjugated bilirubin in the bile, often due to hemolytic conditions [1]. *This is associated with hemolytic disorders* - **Black pigment stones** are strongly associated with conditions causing **chronic hemolysis**, such as **hereditary spherocytosis** or **sickle cell anemia** [1]. - Increased breakdown of red blood cells leads to elevated unconjugated bilirubin, which then precipitates in the gallbladder [1]. *Soft and crumble easily* - **Black pigment stones** are typically **small, multiple, and brittle**, often described as soft and crumbling easily. - This characteristic texture distinguishes them from cholesterol stones, which are usually harder. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, pp. 882-883. [2] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed.

Q: A 32-year-old male with a history of klebsiella infection presents with right upper quadrant pain and on performing cholecystectomy the following stones were seen. All the following statements are true regarding this condition except: (Recent NEET Pattern 2016-17)

It is composed of calcium palmitate. ***It is composed of calcium palmitate*** - The gallstones formed in the context of **Klebsiella infection** and **beta-glucuronidase** activity are typically **pigment stones**, specifically **brown pigment stones** [1]. - Brown pigment stones are primarily composed of **calcium bilirubinate** and not calcium palmitate . *This condition is a resultant of secretion of beta glucuronidase* - **Bacterial infection**, particularly with *Klebsiella*, can lead to the production of **beta-glucuronidase** [1]. - This enzyme deconjugates **bilirubin glucuronide** in bile, making it insoluble and promoting the formation of **calcium bilirubinate stones** [1]. *Initiating factor could be ascaris worm* - **Parasitic infections**, such as those by **Ascaris lumbricoides**, can act as a nidus for stone formation in the biliary tree. - The presence of the worm or its eggs can lead to **biliary stasis** and recurrent infections, contributing to pigment stone formation. *This is radiolucent in nature* - **Pigment gallstones**, including brown pigment stones, are generally **radiolucent** on plain X-rays. - This is because they contain little to no calcium carbonate, which is required for radiopacity. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, pp. 882-883. [2] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, p. 882.

Q: Which is true about the inclusion bodies seen in specimen of patient, who underwent a liver transplantation?

Basophilic intranuclear inclusion. ***Basophilic intranuclear inclusion*** - The classic inclusion bodies of **Cytomegalovirus (CMV)**, a common opportunistic infection post-transplant, are **basophilic intranuclear inclusions** often described as "owl's eye" inclusions [1]. - These are found within the nucleus of infected cells, particularly in patients who have undergone **liver transplantation** and are immunosuppressed. *Seen with supravital stain* - **Supravital stains** are used to visualize living cells or structures within them, such as reticulocytes (with new methylene blue) or mitochondria. - CMV inclusion bodies are typically seen on **histopathological examination** of fixed tissue sections stained with H&E, not with supravital stains. *Intracytoplasmic inclusion* - While CMV can also produce **small, eosinophilic intracytoplasmic inclusions** [1], the most characteristic and diagnostic feature is the **large, basophilic intranuclear inclusion**. - Other viruses, like rabies (Negri bodies) or vaccinia, are known for prominent intracytoplasmic inclusions. *Highly sensitive for diagnosis of CMV* - While the presence of these inclusions is **highly specific** for CMV infection, their **sensitivity** can be variable, especially in early or mild infections. - **Molecular methods** like PCR for CMV DNA in blood or tissue are often more sensitive for diagnosis, particularly in the context of transplant patients. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Infectious Diseases, pp. 367-368.

Q: All are true about the sectioned slice of liver except:

Changes are irreversible. ***Changes are irreversible*** - **Fatty change** (steatosis) in the liver, which is the most likely condition described by the other options, is generally considered a **reversible** process if the underlying cause is removed [1][2]. - Irreversible changes typically refer to processes leading to **cell death** or **fibrosis/cirrhosis**, which are not directly implied by the description of a sectioned slice with fat accumulation. *Occurs due to intracellular accumulation of triglycerides* - **Fatty liver** (steatosis) is indeed characterized by the **intracellular accumulation of triglycerides** within hepatocytes [2][3]. - This accumulation can be due to various causes, including alcohol, obesity, and metabolic syndrome. *H and E stain results in non-staining vacuoles* - In **fatty liver**, the accumulated lipids are dissolved during tissue processing for H&E staining, leaving behind **empty, clear vacuoles** within the hepatocytes [1][2]. - These vacuoles appear **non-staining** because the lipid content is lost. *Tense glistening capsule with rounded margins* - A liver with significant **fatty change** often appears **enlarged**, with a **tense, glistening capsule** and **rounded margins** due to the increased volume from lipid accumulation [2]. - This macroscopic appearance is characteristic of a steatotic liver. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Cellular Responses to Stress and Toxic Insults: Adaptation, Injury, and Death, pp. 51-53. [2] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, pp. 848-850. [3] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, p. 852.

Q: Identify the stain shown in the liver section.

Gordon and Sweet's reticulin stain. ***Gordon and Sweet's reticulin stain*** - The image shows **reticular fibers** in the liver, which appear as a delicate, branching network stained in **black**. This pattern is characteristic of a reticulin stain. - Reticulin stains are used to evaluate the **hepatic architecture** and detect its disruption in various liver diseases like cirrhosis. *Warthin starry* - The **Warthin-Starry stain** is primarily used to detect **spirochetes** (e.g., *Treponema pallidum* for syphilis) and certain bacteria like *Helicobacter pylori*. - It would show these organisms as black or brown, usually in a tissue section, but not the widespread network of reticular fibers seen here. *Steiner silver stain* - The **Steiner silver stain** is another type of silver impregnation stain used to detect **spirochetes** and other microorganisms, similar to Warthin-Starry. - It would not highlight the reticular fiber network of the liver in this specific pattern. *Grimelius silver stain* - The **Grimelius silver stain** is used to identify **neuroendocrine cells** and their granules, especially in tumors like carcinoids. - It stains the argyrophilic granules within these cells dark brown or black, which is distinct from the reticular network observed in the image.

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.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, p. 882.
