[Very extensive ulcers in a case of mixed cryoglobulinemia].

A young girl suffering from mixed cryoglobulinemia had shown since puberty ulcers of the lower limbs. A first very serious occurrence of necrotic lesions of the feet was stopped through the use of bilateral lumbar sympathectomy and grafts. A second extremely serious onset was cured using peridural lumbar anesthesia maintained for six weeks. D-penicillamine proved inefficient.
