Liver and Biliary Pathology Practice Questions

Q: The following liver specimen shows:

Nutmeg liver. ***Nutmeg liver*** - **Nutmeg liver** is a gross pathological appearance of the liver due to **chronic passive congestion**, often seen in **right-sided heart failure** [1]. - The variegated appearance resembles a nutmeg due to alternating areas of **congested centrilobular veins** (darker) and **unaffected periportal areas** (lighter) [1][2]. *Post necrotic cirrhosis* - **Post necrotic cirrhosis** is characterized by broad fibrous bands and large regenerative nodules, often following massive hepatic necrosis. - The gross appearance would typically show a **shrunken, nodular liver** with extensive fibrosis, not the specific variegated pattern of nutmeg liver. *Dubin-Johnson syndrome* - **Dubin-Johnson syndrome** is a hereditary disorder causing conjugated hyperbilirubinemia due to impaired bilirubin excretion. - The liver is typically **macroscopically black** due to the accumulation of a dark pigment (epinephrine metabolites) within hepatocytes, which is distinct from the nutmeg appearance. *Miliary TB* - **Miliary tuberculosis** of the liver presents with numerous small, scattered **granulomas** (tubercles) throughout the liver parenchyma [3]. - Grossly, this would appear as **multiple tiny, pale nodules** resembling millet seeds, not the characteristic congested pattern of nutmeg liver. **References:** [1] Kumar V, Abbas AK, et al..

Q: The liver specimen is diagnostic of:

Nutmeg liver. ***Nutmeg liver*** - This term describes the gross appearance of a liver affected by **chronic passive congestion**, often due to right-sided heart failure [1][3]. - The mottled appearance resembles a cut nutmeg, with dark, congested central veins and paler, fatty peripheral zones [1][2][3]. *Post necrotic cirrhosis* - This is a type of **cirrhosis** resulting from massive or submassive hepatic necrosis, often due to viral hepatitis or drug toxicity. - Histologically, it shows broad bands of fibrosis with regenerating nodules, not the characteristic congestion pattern of nutmeg liver. *Chronic venous congestion of liver* - While "nutmeg liver" is the gross appearance of chronic venous congestion, this option is less specific [2]. - The term "nutmeg liver" specifically refers to the **macroscopic appearance** caused by this congestion [1][3]. *Dubin-Johnson syndrome* - This is a rare, benign, inherited disorder causing **direct hyperbilirubinemia** due to a defect in bilirubin excretion. - The liver appears **black** grossly due to the accumulation of a dark pigment in hepatocytes, which is distinct from the nutmeg appearance. **References:** [1] Kumar V, Abbas AK, et al..

Q: All are true about the marking X in histopathological specimen from a patient of fatty liver except:

Intranuclear inclusions. ***Best visualized with masson trichrome*** - The marking 'X' refers to **Mallory bodies** (also known as Mallory's hyaline or alcoholic hyaline) [1]. - Mallory bodies are **eosinophilic cytoplasmic inclusions** and are best visualized with **hematoxylin and eosin (H&E) stain**, not Masson trichrome. Masson trichrome is used to highlight **collagen** (fibrosis) [2]. *Eosinophilic aggregates of prekeratin* - Mallory bodies are indeed **eosinophilic aggregates** composed primarily of **intermediate filaments**, including **prekeratin** (cytokeratin 8 and 18) [3]. - This description accurately characterizes the composition and staining properties of Mallory bodies. *Intranuclear inclusions* - Mallory bodies are **cytoplasmic inclusions**, not intranuclear [1][3]. - Intranuclear inclusions are typically associated with viral infections (e.g., CMV, herpes) or certain genetic disorders. *Also seen in Indian childhood cirrhosis* - Mallory bodies are a characteristic feature of **alcoholic liver disease** but can also be found in other conditions, including **non-alcoholic steatohepatitis (NASH)**, **Wilson's disease**, **cholestasis**, and **Indian childhood cirrhosis** [1]. - Their presence in Indian childhood cirrhosis is a known histopathological finding. **References:** [1] Cross SS.

Liver and Gallbladder, p. 852.

Q: The marking X in a histopathological specimen from a patient of fatty liver shows:

Mallory hyaline body. ***Mallory hyaline body*** - **Mallory hyaline bodies** (also known as Mallory-Denk bodies) are characteristic eosinophilic cytoplasmic inclusions found in hepatocytes, often seen in **alcoholic fatty liver disease** and other forms of liver injury [1]. - They are composed of tangled intermediate filaments, primarily **keratin 8 and 18**, and indicate hepatocyte damage [1]. *Councilman body* - **Councilman bodies** are apoptotic hepatocytes, appearing as intensely eosinophilic, shrunken cells with condensed nuclei. - They are typically seen in conditions with widespread hepatocyte apoptosis, such as **viral hepatitis** or **yellow fever**, not specifically fatty liver. *Russell body* - **Russell bodies** are eosinophilic, spherical inclusions found within the cytoplasm of **plasma cells**. - They represent an accumulation of **immunoglobulins** within the endoplasmic reticulum and are associated with chronic inflammation or plasma cell dyscrasias, not liver pathology. *Normal Kupffer cell* - **Kupffer cells** are resident macrophages of the liver, located in the sinusoids. - While they are normal components of liver histology, they do not appear as specific "bodies" or inclusions indicative of fatty liver disease; rather, they are involved in phagocytosis and immune responses. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, pp. 852-854. [2] Cross SS. Underwood's Pathology: A Clinical Approach. 6th ed. Common Clinical Problems From Liver And Biliary System Disease, pp. 388-389.

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. Underwood's Pathology: A Clinical Approach. 6th ed. Common Clinical Problems From Liver And Biliary System Disease, pp. 386-387. [2] Cross SS. Underwood's Pathology: A Clinical Approach. 6th ed. 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.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, p. 850. [2] Cross SS. Underwood's Pathology: A Clinical Approach. 6th ed.

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. Liver and Gallbladder, p. 862. [3] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, p. 882.

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: What type of gallstones are shown in the image from a patient with history of acute cholecystitis?

Cholesterol stones. ***Cholesterol stones*** - The image distinctly shows multiple, **yellowish, translucent stones** within the gallbladder, which are characteristic macroscopic features of **cholesterol gallstones**. - These stones are formed due to an imbalance in bile composition, specifically **supersaturation of cholesterol**, and are the most common type of gallstone associated with acute cholecystitis. *Black pigment stones* - These stones are typically **small, rigid, and dark** (black to dark brown) in color, often resembling gravel. - They are composed primarily of **unconjugated bilirubin polymer** and calcium salts, and are commonly seen in conditions like **hemolytic anemias** or cirrhosis. *Strawberry gallbladder* - This is a condition called **cholesterolosis**, where cholesterol deposits accumulate within the gallbladder mucosa, giving it a **strawberry-like appearance** due to prominent yellow flecks against a red background. - While it involves cholesterol, it refers to the mucosal changes, not the presence of discrete, large stones in the lumen. *Brown pigmented stones* - Brown pigment stones are soft, greasy, and tend to be **laminated**. They are primarily composed of **calcium bilirubinate** and fatty acid calcium salts. - They are typically associated with **biliary tract infections** and stasis, and are often seen in the bile ducts rather than solely in the gallbladder.
