[Meningeal myelomatosis as an exclusive form of recurrence in a case of IgA-lambda myeloma in complete systemic remission].

: Meningeal myelomatosis is an extremely rare clinical presentation generally associated to terminal states of the disease and is more frequent in the presence of peripheric plasmocytosis or leukemia of the plasmatic cells. Diagnosis requires its demonstration in the cephalorhachidian liquid and its monoclonal secretion. A case of relapse of meningeal myelomatosis in a patient with multiple IgA-lambda myeloma is presented in which the systemic disease fulfilled the criteria for complete remission.
