Chronic Caffey's disease in an uncommon condition in children is characterized by an acute inflammatory reaction in the periosteum along with systemic disturbances. A 30 months old boy was reported in the pediatric unit of BSMMU, Dhaka about two and half years back with the complaints of multiple painful soft tissue swelling in different parts of the body since birth and delay in growth and development. The child was found well and alert, moderately pale, febrile with hard, tender swelling of mandible on both sides. There were multiple swellings over the right arm, forearm, both thighs and bowing of the lower limbes. Investigations revealed normal serum calcium and phosphate level with mild elevation of alkaline phosphatase. Radiological findings showed periosteal new bone formation in mandible and long bones. There was diaphyseal expansion of the long bones with expansion of the ribs anteriorly. He was diagnosed as a case of chronic caffey's disease on the basis of history, clinical examination and investigation.
