[Wegener's granulomatosis in the elderly. Report of 3 cases]. / Granulomatosis de Wegener del anciano. Descripción de tres casos.

Wegener's Granulomatosis (W.G.) is a systemic vasculitis which the usual age of presentation is the fourth and fifth decades. It seldom appears in the aged patients and it often exists a greater delay in the diagnosis time and in the beginning of therapy in them. We present three cases of W.G. in aged patients (66, 79 and 80 years). One case was diagnosed in the autopsy and the two others had a favourable evolution after therapy. We insist on the need of using all the available tools in order to confirm the W.G. diagnostic, in spite of the aging. The therapy of these patients must be as vigorous as in the young patients in order to avoid the development of renal failure, the most important cause of death in this disease.

[Kikuchi's necrotizing lymphadenitis. Clinical and pathological study of a new case]. / Linfadenitis necrotizante de Kikuchi. Estudio clínico-patológico de un nuevo caso.

Contribution to the topic with the case of a woman, 24, admitted in our ENT Department for exam and treatment of multiple right sided adenopathies of the neck. The histopathological study was consistent with diagnosis of Kikuchi's necrotizing lymphadenitis. This is a new clinicopathologic entity first described, 1972, by Kikuchi, of unknown etiology, an a picture characterized for painful cervical lymphadenitis presented in young women and healing spontaneously after 2-3 months course. We want to emphasize in this paper the scarcity of cases published and the difficulties arising when dealing with the differential diagnosis with lympho-proliferative malignancies as well.

[Primary meningioma of the nose and the paranasal sinus]. / Méningiome primitif nasosinusien.

Primary extracranial and extraspinal meningiomas are not very common, less than 1% out of meningiomas and with a pathogeny not well defined. Less than 60 cases have been described so far. The histopathological diagnosis can be really difficult. All the cases published were diagnosed after an anatomopathological study. We reviewed all publications about these tumors, which belong to the group of those rare neoplasms the otorhinolaryngologist must have in mind whenever he faces a paranasal sinus neoformation.
