An unusual foreign body in oesophagus.

Foreign body in the esophagus is not an unusual finding. Coin in children and bone fragments in adults are commonly observed foreign bodies. Usually foreign bodies are removed within few hours to few days. Forgotten or unattended foreign bodies are seen in either mentally retarded patients or in children. We are reporting here a case, having unusual foreign body in oesophagus, i.e. a thorn of babul tree since one month, presented as perioeso-phagitis with dysphagea in a mentally retarded child of 12 years.
