The camptodactyly-arthropathy-coxa vara-pericarditis syndrome (CACP) is a rare autosomal recessive disease characterized by congenital or early-onset camptodactyly, childhood-onset non-inflammatory arthropathy associated with synovial hyperplasia, constrictive pericarditis and coxa vara. This rare disease is caused by mutations in PRG4 Gene which encodes for lubricin, a protein present in synovial fluid responsible for lubrication. The case we are reporting is of 9 and half years old boy who presented to us in pediatric Out Patient Department with early onset camptodactyly and non-inflammatory arthropathy. Synovial biopsy shows synovial hyperplasia with numerous CD68 positive multinucleated giant cells. He was discharged and physiotherapy was advised with regular follow ups.
