Plastic embedding of transbronchial biopsy specimens for light microscopy.

Abstract
Two methods for embedding human transbronchial biopsy material are discussed. This is the first application of these methods to the study of lung pathology. The first uses hydroxyethyl methacrylate; the 2nd an epoxy resin first described by Spurr in 1969. Both techniques are applicable to larger biopsies or postmortem material with appropriate minor modifications.
