Caffey disease is characterized by massive subperiosteal new bone formation (usually involving the diaphyses of the long bones as well as the ribs, mandible, scapulae, and clavicles) typically associated with fever, joint swelling, and pain in children, with onset between birth and five months and spontaneous resolution by age two years. Episodes of recurrence of the manifestations of Caffey disease have been reported multiple times in individuals with the classic infantile presentation. Limited follow-up information suggests that adults who had Caffey disease in childhood may manifest joint laxity, skin hyperextensibility, hernias, short stature, and an increased risk for bone fractures and/or deformities.
