Sarcoidosis presenting as a lobar or unilateral lung infiltrate.

We present five cases of biopsy proven pulmonary sarcoidosis with initial radiographic localisation of disease to one lung. Four of the cases later demonstrated more typical diffuse bilateral pulmonary infiltrates. Clinical and pulmonary function data of these patients are presented. Although localised pulmonary involvement by Sarcoidosis may not be uncommon, we have found only limited discussion of this radiographic picture in the literature. Our cases and a review of the available literature are the subject of this paper.

False negative biopsy in Pneumocystis carinii pneumonia.

Unlike most pneumonias, the diagnosis of Pneumocystis carinii pneumonia is based solely on identifying organisms by stain, usually with methenamine-silver. Because of technical problems involved with adequate staining, control samples usually are done concurrent with tissue specimens to be examined. Lung containing fungi often is used as a control. We recently observed false-negative biopsy specimens in a case of P carinii pneumonia where the Pneumocystis organism failed to stain with methenamine-silver on several occasions, although fungal controls were positive. This report emphasizes the importance of using P carinii as a control whenever attempting to diagnose P carinii pneumonia.
