title: [Immunocytoma with acquired C1-esterase inhibitor deficiency and recurrent angioneurotic edema].
abstract: Four attacks of mucosal angioneurotic oedema occurred in a 57-year-old woman, requiring tracheotomy for one episode. Decreased or non-measurable levels of complement components C1q, C-1-INH and C4 pointed to a complement consumption. The basic disease was a pleomorphic immunocytoma with the production of monoclonal IgM. Treatment with danazol, 600 mg daily, raised the serum level of C-1-INH, but not of C4.
