RESUMO
A set of specimens has been collected, preserved, and organized specifically for the teaching of forensic pathology, odontology, and anthropology. Plastination of soft tissue, whole organs, bones, and teeth has proven valuable in preserving delicate, friable, and calcined specimens. The dry, odorless, biologically inert specimens are durable and resistant to damage caused by handling. Subtle features of soft tissue pathology are well preserved. Patterned injuries change due to shrinkage, but remain easily recognizable. Plastinated whole jaws are still readily identifiable from antemortem records. Radiographic density is essentially unchanged. Putrid and charred specimens become quite manageable.

Infarction of the lumbar and sacral spinal cord was demonstrated at autopsy of a 72-year-old man in whom acute paraplegia developed following coronary artery bypass grafting and atrial septal defect repair with intraoperative insertion of an intraaortic balloon. Autopsy findings showed that infarcts of the spinal cord and other key organs were caused by critical occlusion of small arterioles by cholesterol emboli. These emboli apparently arose as a result of the fragmentation of atheromatous plaques within the aorta during use of the intraaortic balloon pump with subsequent embolization and occlusion of small blood vessels.

Calcification has long been a determinant in the radiologic distinction of a benign pulmonary mass. However, rare examples of calcification without ossification in pulmonary adenocarcinoma and ossification in the bronchial carcinoid have led some investigators to warn against this approach. A case of pulmonary adenocarcinoma with stromal ossification is reported herein. The literature is reviewed for neoplasms that exhibit pulmonary ossification either by primary or metastatic lesions. To our knowledge, this case represents the first report of benign osseous stromal metaplasia in the primary lesion of a pulmonary adenocarcinoma.
