Hypertrophic osteoarthropathy, phalangeal and synovial metastases associated with bronchogenic carcinoma.

Abstract

A 61-year-old woman with bronchogenic carcinoma simultaneously developed hypertrophic osteoarthropathy (HOA), phalangeal metastases, and metastatic carcinoma of the synovium. The right knee synovium showed several blood vessels containing carcinomatous cells. Although the association of HOA phalangeal and synovial metastases in this case is likely a chance occurrence, awareness of this possibility is extremely valuable as it has important therapeutic implications.
