Tuberculosis (TB) is one of the most important public health issues worldwide, and global efforts have altered the TB epidemic. This study analyzed 71 cases of TB at autopsy notified via Taiwan Medical Examiner Surveillance for Lethal Infectious Disease (Taiwan Med-X) between 2012 and 2017 and applied immunohistochemistry to formalin-fixed lung tissue. Tuberculosis was present in 0.57% (71/12,369) forensic autopsy cases in the institute. Among the study cases, 30 (42.3%) cases were newly diagnosed with TB at autopsy, whereas 41 (57.7%) cases were notified before death and have still seen the TB pathological changes. Regarding the death investigation, cause of death was TB accounted for 46.5%, and non-TB, 53.5% (including trauma, 26.8%; other diseases, 19.7%; drowning, 4.2%; and drug abuse, 2.8%, respectively). Compared with the staining signal, immunohistochemistry has better sensitivity than acid-fast staining. This study provides a reassessment of the reference value to estimate the burden of disease caused by TB and emphasizes the importance of biosafety in an autopsy room.
