Hypertrophic osteoarthropathy: Case report and literature review

Abstract

Hypertrophic osteoarthropathy manifests as digital clubbing, subperiosteal new bone formation in tubular bone and diffuse skin hypertrophy. It could be either primary or secondary. We report a 31-year-old man presenting with digital clubbing and diffuse skin thickening which started at puberty. X-rays showed subperiosteal new bone formation. All examinations for secondary causes were negative.
