title: Erdheim-Chester disease.
abstract: A new case of Erdheim-Chester lipoid granulomatosis is described in a 40-year-old man. In this lipid storage disease, characteristic symmetrical osteosclerotic areas are observed mainly in metadiaphyses of long tubular bones. Bone biopsy is mandatory for definite diagnosis, although characteristic radiographic pictures often provide an important clue to the correct diagnosis.
