[Multiple bilateral pulmonary nodules revealing a congenital cystic adenomatoid malformation]. / Lâcher de ballon révélateur d'une malformation adénomatoïde kystique congénitale du poumon.

Congenital cystic adenomatoid malformation (CCAM) of the lung is a rare congenital developmental abnormality, representing about 25% of all congenital lung lesions. It is very rare that presentation is delayed until adulthood. We report a case of 63-year-old woman without notable pathological antecedents in whom a systematic chest X-ray revealed multiple bilateral pulmonary nodules. The patient was asymptomatic and her physical examination was normal. CT scan showed bilateral liquid rounded thin-walled densities of various size, with a homogeneous non calcified content. The diagnosis was based on radiological findings and surgery. The result of histopathological examination obtained by thoracic surgery confirmed CCAM without malignancy. The postoperative follow up showed an excellent recovery.

[Pleural amyloidosis attesting to generalised amyloidosis]. / L'amylose pleurale: manifestation révélatrice d'une amylose généralisée.

During the course of generalised amyloidosis, pulmonary diseases are mainly represented by tracheobronchial involvement and diffuse or nodular parenchymal localizations. The authors report the case of a 61-year-old woman presenting exudative pleural effusion. The diagnosis of generalised amyloidosis in association with multiple myeloma with cardiac and renal involvement was established. A thoracoscopy performed during the investigation of the pleural effusion and the biopsy revealed amyloid deposits in the pleura. The patient died although melphalan/prednisone treatment was initiated. Pleural involvement in amyloidosis is without doubt under-estimated and plays a central role in the creation and persistence of pleural effusion.
