Hypertrophic osteoarthropathy in a child with biliary atresia

Hypertrophic osteoarthropathy is a syndrome characterized by clubbing of the digits of the hand/foot, periosteal reaction and arthralgia or arthritis which is usually secondary to cyanotic congenital heart disease and chronic pulmonary infections. This syndrome rarely occurs in association with chronic liver disease in childhood. Here, we report on a child with biliary atresia who developed arthralgia and arthritis during follow‐up and which was diagnosed as hepatic hypertrophic osteoarthropathy. It is emphasized that hypertrophic osteoarthropathy should be considered in the differential diagnosis of arthralgia and arthritis in children with long‐standing chronic liver diseases, especially if finger clubbing is also present.
