title: Perichondritis.
abstract: 5 children with abdominal pain of costochondral origin were seen between October, 1987, and February, 1988. 4 were initially misdiagnosed and had unnecessary and costly investigations and inappropriate treatment. An accurate history and a thorough examination are essential to reach the correct diagnosis. A short course of mefenamic acid was effective in all but one child, who responded to a local injection of methylprednisolone.
