title: [Atypical orbital localisation of a myeloma. Non-excretory myeloma or extramedullary plasmocytoma (author's transl)].
abstract: A description of a non-excretory myeloma located in the orbit. The authors stress the importance of immunofluorescent and ultra-structural studies in the identification of these tumours. They discuss the relationship between multiple myeloma and extra-medullary plasmocytoma and raise the possibility of modes of transmission.
