title: Hypertrophic pulmonary osteoarthropathy heralding relapse of lymphoepithelioma.
abstract: Hypertrophic pulmonary osteoarthropathy is an uncommon paraneoplastic syndrome occasionally associated with nasopharyngeal lymphoepitheliomas. We treated two patients with previously diagnosed lymphoepitheliomas in whom hypertrophic pulmonary osteoarthropathy preceded the recognition of pulmonary metastases. Both patients' disabling arthritic syndromes resolved with effective therapy directed at their neoplasms.
