Hypertrophic osteoarthropathy is a medical condition combining clubbing and periostitis of the small hand joints, especially the distal interphalangeal joints and the metacarpophalangeal joints. Distal expansion of the long bones as well as painful, swollen joints^[3] and synovial villous proliferation are often seen. The condition may occur alone (primary), or it may be secondary to diseases like lung cancer. Among patients with lung cancer, it is most associated with adenocarcinoma and least associated with small cell lung cancer. These patients often get clubbing and increased bone deposition on long bones. Their presenting signs and symptoms are sometimes only clubbing and painful ankles.^{[citation needed]}
