[A fulminating case of Takayasu's disease (author's transl)].

Takayasu's disease rarely presents as acute episodes of vascular thrombosis, and the authors describe such a case in order to emphasize this fact. A description is given of the various types of clinical picture seen in this disease, for which a final diagnosis can only be made by combining angiographic and histology findings.

[Experimental endovascular electrocoagulation. Use of alternating current and a bipolar electrode (preliminary study) (author's transl)].

Early experimental studies have shown that it is possible to obtain vascular obliteration and clot formation using monopolar direct current electrocoagulation. There is a major risk of rupture of blood vessels if alternating current is used. Using a co-axial bipolar electrode and high frequency alternating current it was possible to obtain valid, reproducible, and safe vascular obliteration in the distal digestive tract arteries in dogs. The obliteration is due to lesions of the intima and the formation of a clot in situ.

[Specific ENT involvement in a case of angio-immunoblastic adenopathy (author's transl)].

The authors report the case of a 78 year old man with an unusual localization (soft palate and tonsil) of an angio-immunoblastic lymphadenopathy. Clinically, the syndrome combines fever, a marked change in general condition, multiple lymphadenopathy and skin rash. From a laboratory standpoint, the picture is dominated by polyclonal hypergammaglobulinemia, often associated with a hemolytic anemia. Histologically, only lymphnode biopsy allows the diagnosis to be made, with the following findings: disruption of the normal architecture of the node, marked vascular neogenesis, presence of acidophilic interstitial substance, lympho-plasmo-immunoblastic proliferation. The course is in general rapidly fatal despite corticosteroids and multiple chemotherapy.

Chondromyxoid fibroma of the nasal bone with extension into the frontal and ethmoidal sinuses: report of one case and a review of the literature.

Chondromyxoid fibroma is a rare benign tumor that usually occurs in the long bones. A 50-year-old patient presented with chondromyxoid fibroma of the nasal bone with extension into the frontal and ethmoidal sinuses. This is the fourth case reported to date in the literature. The clinical manifestations of the tumor were very limited, and the appearance at rhinoscopy was misleading. Radiologic imaging showed a soft tissue lesion invading the adjacent bony structures and the dura mater. Surgery was performed by a combined team of otorhinolaryngologists and neurosurgeons, and total excision of the tumor was achieved. The histologic diagnosis of this tumor is difficult because of its similarities to chondrosarcoma. [Editorial comment: The authors concisely review management of this rare tumor, emphasizing that complete surgical excision, rather than curettage, is required for long term control.]

[Liquid cholesterol crystals, physical substrate of atheroma].

The study of the atheromatous arterial walls has been carried out on fresh specimens by frozen sections and polarization examination. Thus, it has been proven that the first deposits of cholesterol take place in the intima under the form of liquid crystals. These are very susceptible to temperature variations. They turn to liquid globules above 40 degree centigrad and partially reappear under the action of the cold.

[Hemangioendothelioma of bone: A propos of an anatamo-clinical observation].

Malignant hemangioendothelioma, localised to the skeleton of the lower limbs, to the exclusion of any other bony or visceral involvement, complicated by hemolytic anemia and spontaneous fractures, edl to death in spite of bilateral amputation, less than one year after its chance discovery. The multifocal character of the bony lesions, which is common, may suggest either rapidly developing metastases, or multicentric development of the tumour. The clinical, radiological and laboratory signs--pure osteolysis of large size without condensation nor periostosis, are not specific. Pathological examination permits recognition of the vascular origin of the tumour but does not always permit one to recognize its malignant nature. Treatment, which is mainly surgical, is often ineffective.

[Saphenectomy in patients over 65. Indications and results].

For 779 patients who underwent varicose vein surgery at Bicêtre, between 1981 and 1984, there were 61 elderly patients between 65 and 74 years and 15 "old age" patients over 75 years. Only one severe complication occurred. Almost all patients who were operated upon were satisfied or very satisfied to see that the functional discomfort had disappeared, the trophic disorders had regressed, the superficial phlebitis or hemorrhages had not recurred and the ulcer were healed. Statistics are in favor of a surgical treatment of varicose veins or phlebitis sequellae with severe degeneration of the superficial venous network, as soon as they become uncomfortable, because of the increased life expectancy, in Europe at this time. But, because of the tremendous progress of anesthesia techniques, it seems permissible to offer this surgical procedure to those who have passed the age previously considered as reasonable and are quite disabled.
