The purpose of this study was to develop a teaching guide to demonstrate the gross characteristics of pathology in embalmed cadaveric lungs and to and to assess the guide as an effective teaching tool. Ninety-eight embalmed cadaveric lungs were screened for pathology. The characteristics of pathologic states of the embalmed lungs were recorded and histopathologic confirmation was performed. Pneumonia, neoplasms, emphysema, chronic bronchitis and diffuse interstitial lung disease were the most commonly observed pathologic lesions. Discoloration of the parenchyma and edema were the most commonly observed artifacts from the embalming process. Medical and nursing students who used the guide had significantly more ability to identify pathologic lesions than control groups. This guide will assist faculty and students in obtaining the skills needed to examine and interpret the gross presentation of an embalmed cadaveric lung.
