Case ReportsMetastases to primary intracranial meningiomas and neurilemomas.
Five cases of carcinoma metastatic to intracranial meningioma or neurilemoma are presented and compared with 20 similar cases reported in the literature. The phenomenon was most often seen on autopsy (17 of 25 cases) and was found more commonly in females (3:2), with nearly 90% of donor cancers being found in breast or lung. The existence of the donor tumor, which was always found to be widely disseminated, was known prior to autopsy in only half the cases.

Case ReportsPulmonary hemorrhage and immune-complex deposition in the lung. Complications in a patient with systemic lupus erythematosus.
A patient with systemic lupus erythematosus (LE) was admitted with an acute illness characterized by dyspnea, hemoptysis, fever, and diffuse infiltrates revealed by chest roentgenograms. An open-lung biopsy specimen showed massive intrapulmonary hemorrhage, and immunofluorescence and electron microscopic examinations showed granular deposits of IgG within the alveolar walls and pulmonary vessels. ⋯ Her condition again improved over several days, and she has had no pulmonary symptoms for nine months. In some instances, pulmonary hemorrhage in patients with systemic LE may be mediated by polymorphonuclear leukocytes attracted by immune-complex deposits.
