Digital clubbing

The primary hypertrophic osteoarthropathy (pachydermoperiostosis) is a hereditary disease characterized by skin thickening (pachydermia), finger clubbing, and proliferation of periosteum (periostitis) with subperiosteal new bone formation. We describe the cases of 2 brothers of 30 and 24 years, who consulted due to bone pain, arthralgia, and oligoarthritis. Pachydermia, hyperhidrosis, seborrhea, digital clubbing, periostosis, and non-inflammatory effusions of the knees. The first had been diagnosed with juvenile idiopathic arthritis at age 15, while the youngest also presented with a thoracic scoliosis, hypertrophic gastritis, iron deficiency anemia, and glucose intolerance by pancreatic endocrine dysfunction. In both patients, symptoms were controlled satisfactorily with etoricoxib (90 mg/day) and risedronate (35 mg/week)
