Hypertrophic osteoarthropathy (HOA) is an uncommon condition in children, consisting of a triad of digital clubbing, non-inflammatory
joint effusions and radiographic evidence of periostitis affecting the hands, feet and distal long bones. HOA is classified as primary
(idiopathic) or secondary to various diseases. In this case report, we present a patient with secondary HOA associated with biliary atresia
and chronic liver disease.
