[Massive hemoptysis during sarcoidosis]. / Hémoptysies graves au cours de la sarcoïdose.

Hemoptysis is a rare but often severe event in sarcoidosis. It usually occurs in patients with advanced, fibrotic lung disease. We herein report the case of a 36-year old female patient with type II pulmonary sarcoidosis who presented with abundant hemoptysis very early during the course of her disease. Two attempts to embolize bronchial arteries remained unsuccessful and surgery was eventually required to stop the bleeding. Clinical, microbiological, radiological and pathological data indicate that haemoptysis was caused by systemic hypervascularization around sarcoidosis granuloma.

[Pseudo-tumor of Castleman: particular aspects of thoracic localization. Two case reports]. / Pseudo-tumeur de Castleman. Aspects particuliers de la localisation thoracique. A propos de deux observations.

The pseudo-tumours of Castleman, irrespective of whether their histological type is plasmocytic or hyalino-vascular, are most often found in the mediastino-pulmonary area. 2 rare aspects of their thoracic localisation are reported with the occurrence of a pleural effusion and the localisation to the chest wall itself.
