Hypertrophic osteoarthropathy with acro-osteolysis in a patient with primary pulmonary hypertension.

Hypertrophic osteoarthropathy is an entity characterized by a triad of periostitis of long bones, clubbing and arthritis. Radiologically there are two patterns, one characterized by new bone formation which predominates in patients with pulmonary disease, and another by acro-osteolysis that is most frequently associated with congenital heart disease. We report the case of a 30-year-old man diagnosed with primary pulmonary hypertension for two years, developing hypertrophic osteoarthropathy with a mixed radiological pattern.
