Tuberculous lymphadenitis and borderline leprosy in a patient with isolated unconjugated hyperbilirubinaemia.

A 35-year-old man was diagnosed with tuberculous lymphadenitis and multibacillary borderline tuberculoid leprosy. On investigation, isolated unconjugated hyperbilirubinaemia was detected and evaluation led us to conclude that the probable cause was Gilbert's syndrome. He was successfully managed by administration of chemotherapy for the treatment of both the mycobacterial infections, with no adverse effects on liver function tests.
