Hypertrophic pulmonary osteoarthropathy in pulmonary metastasis--a case report.

Hypertrophic pulmonary Osteoarthropathy is most commonly encountered in association with bronchogenic carcinoma and tumours of the pleura. Its association with pulmonary metastasis from extrathoracic neoplasms is rare. We report a 33 years old male Ethiopian who presented with Cannon ball lesions, clubbing of the digits, periostitis, gynaecomastia, acromegalic features and bilateral knee arthritis.
