Hypertrophic osteoarthropathy effectively treated with zoledronic acid.
Hypertrophic osteoarthropathy (HOA) is a syndrome characterized by digital clubbing, arthralgias, and tissue swelling and is frequently described in association with bronchogenic carcinoma. The associated pain can be disabling, and symptoms are often resistant to conventional analgesic medications. We present a patient with HOA of the lower extremities and wrists that developed after bronchogenic carcinoma. The pain and swelling completely resolved after a single administration of 4 mg of zoledronic acid. The proposed pathogenesis of HOA and the mechanisms by which bisphosphonates might alleviate symptoms are reviewed.
