[Pulmonary lymphangioleiomyomatosis and sex hormones]. / Lymphangioléiomyomatose pulmonaire et hormones sexuelles.

The authors having prepared for a case of pulmonary lymphangioleiomatosis point out the diagnostic boundaries of this condition with benign metastasizing intravenous leiomyomas of the uterus, pulmonary localisation of Bourneville's tuberous sclerosis and the important aetio pathologic role of sex hormones. Finally they deal with the therapeutic management and the various uses of hormones to inhibit oestrogenic activity.

[Pulmonary metastasis of a hemangiopericytoma of the tongue disclosed by pneumothorax]. / Métastase pulmonaire d'un hémangiopéricytome de la langue révélée par un pneumothorax.

The authors report a case of recurrent haemangiopericytoma of the tongue complicated with a single pulmonary metastasis revealed by a spontaneous pneumothorax.

Pulmonary sarcoidosis with an alveolar radiographic pattern.

Thirty-three cases of sarcoidosis (4.4% of 746 patients) showed an alveolar radiological pattern. A study of pulmonary function was carried out in 25 patients and compared with that of 46 patients with the interstitial radiological type of sarcoidosis. Twenty-two cases have been followed up from one to six years after the initial examination. The radiographic lesions were most often bilateral and included nodules greater than 15 mm with ill-defined margins or diffuse, infiltrative, non-retractile opacities with fluffy margins. Bilateral mediastinal lymph nodes were present in 27 patients. In 20 patients an associated reticulation was found on radiography. In four patients an open lung biopsy was done. The granulomatous nodules were identical to those found in other forms of sarcoidosis, although they were more confluent in the affected areas. Clinical and functional findings did not differ from those in the more common forms of sarcoidosis. Alveolar sarcoidosis has a sudden course. The alveolar radiological patterns always disappeared, with or without steroid treatment, while reticular patterns persisted in four patients. Rapid radiological changes were observed. Some functional abnormalities persisted in cases that were followed. It is concluded that alveolar sarcoidosis is a distinct acute form of sarcoidosis.
