title: [Extraskeletal plasma cell tumors (author's transl)].
abstract: Extraskeletal plasmacytomas are very rare malignant plasma cell tumors. They often seem to arise from a pathologic plasma cell reaction to an antigenic stimulation and are characterized by the variety of their locations and the frequent absence of monoclonal dysproteinemia. The authors are reporting three new observations of extraskeletal plasma cell tumors. Some pathological, biological and pathogenic features of these tumors are emphasized.
