Postmortem inspection is a specialized medical practice that determines the cause and manner of death via external examination of a corpse. It is performed as part of the medico-legal death investigation and a crucial step in determining whether an autopsy is necessary. In South Korea, training for doctors performing postmortem inspection and quality control for postmortem inspection results remain lacking. Therefore, the Korean Society for Legal Medicine established a task force and proposed a standard operating procedure (SOP) of postmortem inspection. This article includes the background for proposing this SOP, an introduction to the postmortem inspection process, and the principles for performing the procedure and writing the report. This SOP may serve as a basic guideline for postmortem inspection.

Myiasis, a parasitic infestation caused by dipteran larvae in living humans or animals, is rarely encountered postmortem. Here, we report a case of myiasis identified during postmortem inspection in a 40-year-old man with a 10-year history of untreated schizophrenia. During the winter between late 2022 and early 2023, the decedent walked outdoors barefoot and sustained frostbite and was advised to undergo limb amputation at a university hospital in March 2024. He died at home in late May 2024. At the scene, the body showed displaceable livor mortis and absence of rigor mortis, suggesting a short postmortem interval. Severe necrosis was present below the knees, and numerous third-instar larvae without postfeeding stage were observed within the necrotic tissue, suggesting myiasis development at the frostbite sites. Species identification via larval sampling was not possible; thus, photographic analysis was attempted. The larva at the most advanced developmental stage was most likely a third-instar Lucilia sericata, the most common species causing myiasis in Korea. Assuming a skin temperature of 34°C under blanket coverage, the estimated post-oviposition interval ranged from 38.9–71.7 hours. Considering the estimated postmortem interval, the oviposition may have occurred antemortem. Since myiasis can indicate neglect or contribute to death, forensic pathologist should assess whether the postmortem interval aligns with the developmental stage of the larvae. For accurate forensic entomological analysis, adequate sampling of larvae is essential during postmortem inspections.

Spontaneous coronary artery dissection (SCAD) is a condition in which an intramural hematoma within the coronary artery leads to acute coronary syndrome without atherosclerosis, trauma, or iatrogenic causes. It predominantly affects middle-aged women and is associated with several predisposing conditions, including fibromuscular dysplasia, systemic inflammatory disorders, connective tissue diseases, and coronary artery spasms. We report the case of a 64-year-old male with a history of hypertension who died of SCAD. His death occurred suddenly and without preceding trauma while the decedent was working overtime at a construction site. On gross examination, a thrombus-like material was identified in a branch of the left anterior descending artery and was initially presumed to be a postmortem clot. However, microscopic examination revealed an intramural hemorrhage, medial dissection, and formation of a false lumen within the coronary artery. This case report highlights the importance of a thorough histopathological examination of the coronary arteries during autopsy, even in the absence of atherosclerosis.

In the quest to combat insulin-dependent diabetes mellitus (IDDM), allogenic pancreatic islet cell therapy sourced from deceased donors represents a significant therapeutic advance. However, the applicability of this approach is hampered by donor scarcity and the demand for sustained immunosuppression. Human induced pluripotent stem cells are a game-changing resource for generating synthetic functional insulin-producing β cells. In addition, novel methodologies allow the direct expansion of pancreatic progenitors and mature β cells, thereby circumventing prolonged differentiation. Nevertheless, achieving practical reproducibility and scalability presents a substantial challenge for this technology. As these innovative approaches become more prominent, it is crucial to thoroughly evaluate existing expansion techniques with an emphasis on their optimization and scalability. This manuscript delineates these cutting-edge advancements, offers a critical analysis of the prevailing strategies, and underscores pivotal challenges, including cost-efficiency and logistical issues. Our insights provide a roadmap, elucidating both the promises and the imperatives in harnessing the potential of these cellular therapies for IDDM.

Ethylene glycol (EG), commonly used as antifreeze, is frequently ingested accidentally or in suicides, and causes acute renal failure. We report an unusual case of EG poisoning with acute liver injury. After vomiting and loss of consciousness, a 48-year-old male was admitted to the emergency room. Despite prompt conservative treatment for metabolic acidosis, kidney function deteriorated, necessitating the continuous renal replacement therapy. Blood toxicology results, showing EG levels of 510 mg/L, arrived 10 hours after admission. Oral ethyl alcohol therapy commenced 16 hours post-admission. By 36 hours, liver function tests indicated significant liver damage, and the patient died 45 hours upon admission. On autopsy, histological findings were hepatic centrilobular necrosis, cerebral perivascular neutrophilic and lymphocytic infiltration with calcium oxalate deposition, and renal tubular necrosis with calcium oxalate deposition. EG concentrations in the blood and gastric contents were 18.7 mg/L and 45.0 mg/L, respectively. Glycolic acid and oxalic acid, metabolites of EG produced by alcohol dehydrogenase in the liver, cause metabolic acidosis, renal tubular calcium oxalate deposition, and acute renal failure, leading to death. Generally, because fomepizole or ethyl alcohol block alcohol dehydrogenase in the liver, acute liver injury by EG poisoning is rare. To the best of authors’ knowledge, only one relevant report was found in the literature described a case in which EG caused centrilobular necrosis in liver. In the current case, delays in diagnosis and antidote therapy without gastric lavage allowed continued metabolism of EG which led to acute liver injury and acute renal failure.

Ludwig’s angina is a rapidly progressive and gangrenous cellulitis in the submandibular, sublingual spaces, and neck. It is characterized by an elevated tongue and laryngeal edema, resulting in airway compromise and, rarely, in sudden death. The most common cause is an odontogenic infection of a molar tooth. Infection can spread to the superior mediastinum and buccal area through anatomical structures. Herein, we report the sudden death of a 45-year-old male who was not diagnosed with Ludwig’s angina. He died in the emergency room 20 minutes after loss of consciousness. Intubation was impossible owing to severe laryngeal edema. The C-reactive protein level was 33.81 mg/dL. On autopsy, a diffuse light green abscess of the submandibular space was detected, along with severe edema of the epiglottis, aryepiglottic fold, and vocal cords. Subsequently, we confirmed that the airway obstruction was caused by Ludwig’s angina based on a literature review. In conclusion, this report emphasizes the need to identify the infection source and perform a detailed dissection according to the anatomical structure in the autopsy procedure for Ludwig’s angina.

The incidence of breast cancer is increasing worldwide. As cancer screening has become more widespread, the rate of early breast cancer detection has increased and treatment methods have changed. Partial mastectomy is performed more often than total mastectomy for the surgical treatment of early breast cancer, and sentinel lymph node biopsy plays an important role. A high level of accuracy is necessary for the intraoperative examination of surgical margins and sentinel lymph nodes to identify malignancies. Therefore, several examination techniques, including Raman spectroscopy, that replace or supplement the currently used frozen-section methods are being studied. Raman spectroscopy has the ability to diagnose cancer in normal tissue by providing in real time a chemical fingerprint that can be used to differentiate between cells and tissues. Numerous studies have investigated the utilization of Raman spectroscopy to identify cancer in the margins of resected tissues and sentinel lymph nodes during breast cancer surgery, showing the potential of this technique for clinical applications. This article introduces and reviews the research on Raman spectroscopy for breast cancer surgery.
