Pycnodysostosis: report of a case

Pycnodysostosis is a rare systemic bone disease whose cardinal features are generalized osteosclerosis and dwarfism. Characteristic skeletal defomities ensue, such as failure of closure of cranial sutures, obliquity of the mandibular angle, and defects of the terminal phalanges. This disease is suspected to be congenital heredity. In this report, a case of pycnodysostosis of a 20-year-old man with pathological fracture caused by osteomyelitis was presented. We discussed the treatment of osteomyelitis associated with this disease.
