Others

Asterixis
Signs of Cirrhosis of Liver
Jaundice
Jaundice is not a common feature of cirrhosis, its more common with acute diseases.
Mechanisms of jaundice in cirrhosis:
Failure to excrete bilirubin (mainly)
Intrahepatic cholestasis (superadded hepatitis/tumor)
Hemolysis due to hypersplenism (not a major contributor).
Hepatomegaly
Early stages: Liver is enlarged, firm to hard, irregular, and non-tender. Hepatomegaly is not common
in cirrhosis but common when the cirrhosis is due to alcoholic liver disease, nonalcoholic
steatohepatitis (NASH) and hemochromatosis. Hepatomegaly may indicate transformation into
hepatocellular carcinoma (HCC).
Late stages: Liver decreases in size and non-palpable due to progressive destruction of liver cells
and accompanying fibrosis.
Ascites
Ascites due to liver failure and portal hypertension.
It signifies advanced disease.
(discussed in detail below)
Spider Naevi
Spider nevi (Fig. 5D.1)
(Spider telangiectasia; vascular spiders; spider angiomas; arterial spiders, and nevus araneus)
Description Consists of a central arteriole from which numerous small vessels radiate peripherally-resembling spider’s
legs. Whole spider disappears when central arteriole is compressed with a pinhead. When compression is
released filling occurs from center to periphery
•
•
•
•
•
•

•

•
Pathophysiology Due to arteriolar changes induced by hyperestrogenism
Location Usually found only in the necklace area, i.e. above the nipples, territory drained by the superior vena cava,
such as: head and neck, upper limbs, front and back of upper chest
Size Vary from pinhead to 0.5 mm in diameter
Clinical
demonstration
Applying pressure over the body of spiders with a glass slide (diascopy) (Fig. 5D.2), or pin head (Fig. 5D.3)
leading to pallor with refilling following the release of pressure
Significance They are a strong indicator of liver disease but can be found in other conditions
Causes Liver disorders Others
Viral hepatitis
Alcoholic hepatitis
Hepatocellular carcinoma
Treatment with sorafenib
Third trimester of pregnancy
Rheumatoid arthritis
Thyrotoxicosis
Also normally seen in 2% of healthy population
Differential
diagnosis
Venous star, Campbell de Morgan spots, petechiae, and hereditary hemorrhagic telangiectasias
Note:
Florid spider telangiectasia, gynecomastia, and parotid enlargement are most common in alcoholic
hepatitis.
Florid spiders and new onset clubbing in a patient with cirrhosis indicates hepatopulmonary
syndrome.
Palmar Erythema (Liver Palm)
Can be seen early but is of limited diagnostic value, as it occurs in many conditions associated with a
hyperdynamic circulation (e.g. normal pregnancy).
Fig. 5D.1: Cirrhosis of liver with ascites and spider nevi. Patient in addition has tattoo and keloid—
which may suggest viral hepatitis as the cause of cirrhosis.

Fig. 5D.2: Demonstration of spider naevi (glass slide method).
Fig. 5D.3: Demonstration of spider nevi (pin head method).
Cause: Develops due to increased peripheral blood flow. In cirrhosis, circulatory changes results in
increased peripheral blood flow and decreased visceral blood flow (especially to the kidneys).
Sites involved: Prominent in the thenar and hypothenar eminences of palm. Spares the central
portion of the palm. May be seen on the sole.
Endocrine Changes
Diminished body hair and loss of hair: Seen mainly in males with loss of male hair distribution.
Alopecia affects usually the face, axilla and chest and is due to hyperestrogenism. Causes of
hyperestrogenism: Due to increased peripheral formation of estrogen resulting from diminished
hepatic clearance of the precursor, androstenedione. Effects of hyperestrogenism: Alopecia,
gynecomastia, and testicular atrophy.
Hyperglycemia: 80% of cirrhotics have impaired glucose tolerance, 20% develop diabetes.
Gynecomastia (Fig. 5D.4): Found in males (atrophy of breasts in females).
Cause: Due to increased estradiol/free testosterone ratio.
Examination (Fig. 5D.5): Appear as palpable nodule (4 cm, subareolar).
Microscopy: Proliferation of glandular tissue of breast.
Pseudogynecomastia is accumulation of subareolar fat tissue without palpable nodule. Seen in obesity
and Cushing’s syndrome:

Causes of gynecomastia
Cirrhosis of liver
Drugs:
Spironolactone
Cimetidine
Digoxin
Ketoconazole
Estrogens
Isoniazid/Antiandogens
Physiological (puberty/ageing)
Klinefelter’s syndrome
Hypogonadism
Tumor:
Testes
Lung
Testicular Atrophy
Due to hyperestrogenic state, it is characterized by a small size compared with Prader’s orchidometer
(Fig. 5D.6), soft testes with loss of testicular sensation (sickening sensation in epigastrium on squeezing
the testes). The dimensions of the average adult testicle is 4.5 × 3.5 × 2.5 cm and the volume is 15–25
mL.

Fig. 5D.5: Palpation breast bud in gynecomastia.
Fig. 5D.6: Prader’s orchidometer.
Endocrine changes in females
Irregular menses, amenorrhea, and atrophy of breast.
Dupuytren’s Contracture (It is a Sign of Alcoholism)
Pathophysiology Fibrosis of palmar aponeurosis probably caused by local microvessel ischemia. Platelet and
fibroblast-derived growth factors promote fibrosis
Sites involved Flexion contracture of the fingers (Fig. 5D.7) (especially ring and little fingers)
Other causes of
Dupuytren’s contracture
Diabetes mellitus, rheumatoid arthritis, and manual labor (workers exposed to repetitive handling
tasks or vibration).
Clubbing and Central Cyanosis
Due to development of pulmonary arteriovenous shunts that leading to hypoxemia (Orthodeoxia—
Platypnea syndrome).
Nail Changes
White (Terry’s) chalky and brittle nails (Fig. 5D.8). And it can be easily demonstrated on comparison
with normal person nails when placed side by side (Fig. 5D.9).
•
•
•
Muehrcke’s nails: Characterized by transverse white lines that disappear on applying pressure and
these lines do not move with growth of nail.
Clubbing is present in primary biliary cirrhosis or hepatoma.
Parotid and Lacrimal Gland Enlargement (Fig. 5D.10)
Observed commonly in alcoholic cirrhosis due to associated autonomic dysfunction.
Anemia
It can be due to various causes:
Acute and chronic blood loss from varices

side).

Nutritional deficiency of vitamin B12 and folate
Hypersplenism
Bone marrow suppression by alcohol
Hemolysis
Zeives syndrome: Alcohol induced hemolytic anemia with hypercholestrolemia.
Fetor Hepaticus
Sweet, pungent smell
It is due to volatile dimethylsulfide, especially in portosystemic shunting and liver failure and hepatic
encephalopathy.
Asterixis/Flapping Tremor
Asterixis is a disorder of motor control characterized by an inability to actively maintain a position and
consequent irregular myoclonic lapses of posture affecting various parts of the body independently.
It is a type of negative myoclonus characterized by a brief loss of muscle tone in agonist muscles
followed by a compensatory jerk of the antagonistic muscles.
