[T-gamma lymphocytosis associated with two solid neoplasms in a patient with rheumatoid arthritis].

T gamma lymphocytosis is an infrequent entity, generally benign and distinct of the spectrum of the T cell chronic lymphoproliferative syndromes, that it not need or need short therapy, with a prolongated survival. T gamma lymphocytosis is expressive in the most of the occasions of a monoclonal lymphocytic proliferation and it is frequently associated to Rheumatoid Arthritis. We present the case of a patient with T gamma lymphocytosis, developed after several years of evolution of Rheumatoid Arthritis and that it was coincident with two solid neoplasms, an infiltrate carcinoma of the larynx and recurrent urothelial carcinoma, without previous chemotherapy.

Idiopathic granulomatous vasculitis: response to immunosuppressive therapy.

[An evaluation of the clinical significance of gastric dysplasia: a histological follow-up study].
