Cytodiagnosis in the Autopsy Suite: A Tool for Improving Autopsy Quality and Resident Education

Abstract

Abstract Context.—Despite several publications attesting to its accuracy and value, cytology is rarely used for preliminary autopsy diagnosis in the United States. Postmortem cytodiagnosis has the potential to increase the accuracy and specificity of the provisional and final autopsy diagnoses, increase resident interest in cytodiagnostic techniques, and direct pathologists to request pertinent special studies, such as microbial cultures and special stains. Objective.—To assess and illustrate the value of cytodiagnostic techniques for improving autopsy quality assurance and resident education. Design.—Eighty-five samples were evaluated from 49 nonconsecutive autopsies. Sixty-five focal lesions were sampled by direct scraping. Diffuse lung consolidation was sampled by fine-needle aspiration (20 samples). Smears and cytocentrifuge preparations of fine-needle aspirations were routinely stained by both Papanicolaou and Romanowski methods. Cytologic diagnoses were compared with final autopsy diagnoses, and bot...
