[Vascular neoplasms in the ORL organs (anatomic-clinical observations)]. / Neoplaziile vasculare în O.R.L. (observatii anatomoclinice).

The paper presents two cases of vascular neoplasias: a case of larynx angiosarcoma and a case of angiopericytoma of the root of the tongue. The incidence of the various forms of tumoral proliferations of vascular origin is very rare. The anatomopathologic aspects and the clinical, biological and evolution characteristics of the two cases are analysed according to the recent data in the literature.

[Rare tumors of the larynx. 2 cases]. / Tumeurs rares du larynx. Deux cas.

Two rare tumors of larynx are reported, one an angiosarcoma and the other an amyloid tumor. Histopathological, clinical and biological characteristics and course of the disease are analyzed in the light of recent documented data in the literature.

[Results of treatment of carcinoma of the nasopharynx (author's transl)]. / Résultats thérapeutiques dans le cancer du nasopharynx.

Study of survival amongst a group of 101 patients with epithelial tumours of the nasopharynx treated by cobalt irradiation between 1967 and 1972 indicates the prognostic significance of the following factors: the histological type, extension of the tumour, the degree of lymph node involvement, age and sex. The optimal dose is 1,800 to 2,000 rets NSD and should be modified in the light of these factors, and above all the histological type and the tumour category. Cumulative survival for all cases was 36% at 5 years, with a more favourable prognosis in lympho-epitheliomas in comparison with spindle cell epitheliomas.

[The relationship between the degree of dissemination of pharyngolaryngeal tumours and immunological changes (author's transl)]. / Le rapport entre le degré de dissémination des tumeurs pharyngolaryngées et les modifications immunologiques.

An investigation was carried out on 34 patients with malignant pharyngolaryngeal tumours which had been operated on, microscopic changes in the regional ganglia (sinusal histocytosis, hypertrophy of the germinal centres, the paracortical area, the number of pyroninophilic plasmocytes, the behaviour of the mastocytes) and into certain cell immunity tests (the cytological formula of the inflammatory reaction in the cutaneous window, intracutaneous reaction to tuberculin, the time taken to reject normal skin homografts). The results were correlated with the presence or absence of ganglionic metastases. A relative correlation was found between the absence of metastasis, and manifest sinusal histiocytosis, the hypertrophied paracortical zone, the considerable number of young mastocytes, early mobilisation of macrophages, a normal amount of time taken to reject the cutaneous homograft. These tests enable certain prognostic conclusions to be drawn and draw attention to the need, in some cases, to build up the low level of immunity.
