[Solitary secreting plasmocytoma in a femoral localization in a young man (author's transl)].

A pathological fracture in 20-year-old man led to the discovery of a right femoral plasmocytoma. Immunoelectrophoresis revealed the existence of a monoclonal Kappa IgG. After tumour reduction by radiotherapy and chemotherapy, surgical excision was possible with the insertion of a reconstructive prosthesus. Functional recovery was complete. The dysglobulinaemia completely disappeared and, with a two year follow-up, no dissemination of the plasmocytoma has been found.
