Acute airway obstruction caused by mucoid impaction can cause sometimes life-threatening respiratory distress. Bronchial plugging is usually observed in subjects with chronic diseases such as asthma, allergic bronchopulmonary aspergillosis, or cystic fibrosis. In children, it can be related to heart failure. ⋯ The patient experienced acute respiratory distress with asphyxia. The plugs were composed of fibrin and required several fibroscopic procedures for clearance. To our knowledge, this is the first case report of acute airway obstruction by plugging during a period of agranulocytosis.

Pleural effusion is rarely observed in multiple myeloma, its frequence is estimated at 6%, and its myelomatous origin occurs in only 1% of the cases. It is exceptionally the first sign of multiple myeloma. ⋯ These pleural effusions were found to be caused by myeloma and were verified by the presence of the same monoclonal immunoglobulin in both plasma and pleural liquid. Atypical plasma cells were found in the pleural fluid.

Interstitial lung diseases (ILD) associated with connective tissue disorders differ from idiopathic ILD in several aspects, although most of them are comparable. In most patients, ILD occurs during the course, or at the time of diagnosis of connective tissue disease. Opportunistic pulmonary infections, together with adverse effects of treatment should always be discussed. ⋯ ILD must be detected early in the course of collagen disorders by performing computed tomodensitometry and pulmonary function tests. The prognosis of connective tissue associated ILD is better than that of idiopathic ILD. The treatment requires corticosteroids and/or immunosuppressants, depending on the nature of the associated connective tissue disease and ILD progression.

Bronchoalveolar lavage (BAL) is a minimally invasive method for exploring the distal lung. It enables collection of free cellular and acellular material present in the alveoli. Over the last two decades BAL has become a fundamental tool for positive diagnosis of interstitial lung disease and even more for differential diagnosis. ⋯ With BAL, a number of infectious or tumoral diseases can be ruled out with precision. It is also an important element for the evaluation of possible iatrogenic disease. BAL has transformed the diagnosis of interstitial lung disease and considerably reduced the indications for surgical biopsy.
