Paget's disease of bone and its complications due to delay in diagnosis.

Paget's disease of bone is an osteometabolic focal disease characterized by defects in bone remodeling. It may be asymptomatic, but often is associated with bone pain, deformity, pathological fracture, secondary osteoarthrosis and deafness. The diagnosis is usually made by radiological and laboratory findings. This report describes a male patient, 74 years old, native of Amazon, without European ancestry, with polyostotic Paget's disease, with clinical, radiological and laboratory diagnosis after 30 years of disease. The authors emphasize several complications of Paget's disease due to delayed diagnosis and the rarity of the disease in this population group.
