[Camurati-Engelmann disease (progressive diaphyseal dysplasia). Differential diagnostic problems].

The Camurati-Engelmann disease is characterized by sclerotical hyperostosis, which can appear mainly bilaterally symmetrical at the diaphyses of the long bones, but also at all other bones of the skeleton. The Camurati-Engelmann disease is a rare one, up to now hardly more than 120 cases have been published. The rarity explains the fact that the disease is often misdiagnosed and mistaken for other bone diseases. This is a case report of a Camurati-Engelmann disease which was detected by radiological diagnosis. The problem of differential-diagnosis is described.
