Cutaneous manifestations in disorders of hepatobiliary system

BACKGROUND Hepatobiliary diseases are associated with various mucocutaneous changes that are directly and indirectly associated with these diseases. There is a dearth of studies from India dealing with cutaneous manifestations in liver disorders. AIM This study was conducted to know the spectrum of cutaneous changes and their correlation with liver function tests in patients with disorders of hepatobiliary system. METHODS This was a descriptive study conducted among in patients and outpatients with primary hepatobiliary disorders at a tertiary care center in South India. Detailed history taking and examination was done. Visual analog score (VAS) and 5D itch score was employed to quantify pruritus. Correlation of liver function tests with pruritus and comparison of skin changes in the major disease groups was attempted. RESULTS A total of 303 patients were recruited. Hepatic mass/malignancy followed by nonalcoholic liver disease were the most common diagnoses. Icterus followed by pruritus were the most common cutaneous complaints. The mean VAS and 5D itch scores among the patients with pruritus were 4.7 ± 1.9 and 13.6 ± 4.9. The most common mucocutaneous findings observed were icterus (241 patients; 79.5%), ichthyosis/xerosis (172 patients; 56.7%), pallor (131 patients; 43.2%), excoriations (118 patients; 38.9%), hyperpigmented palmar creases (118 patients; 38.9%), clubbing (113 patients; 37.2%), and pedal edema (85 patients; 28%). There was statistically significant correlation between serum bilirubin levels and pruritus. CONCLUSION The common mucocutaneous manifestations associated with primary hepatobiliary disorders were icterus, ichthyosis/xerosis, pallor, excoriations, hyperpigmented palmar creases, clubbing, and pedal edema.
