Dieulafoy's lesion is a rare condition that may cause intermittent or massive gastrointestinal bleeding. It is characterized by the exteriorization of an arterial vessel into the lumen of the affected organ, generally the upper digestive tract, through an apparently normal mucosa or a small tear or erosion. We report two patients with Dieulafoy's lesions, one in whom the lesion was misdiagnosed as a submucosal tumor and endoscopic biopsy resulted in fatal bleeding.

Thoracic aortic aneurysms are less common than abdominal aortic aneurysms, however they are life-threatening and usually asymptomatic until acute complications occur. The majority of thoracic aorta aneurysm are associated with medial degeneration rather than atherosclerosis and the fusiform aortic aneurysm is common. Considering that it usually occurs during the sixth and seventh decades of life, its occurrence in a peripartum woman is unusual. Aortic dissection or thoracic aortic aneurysm with aortic insufficiency during pregnancy or peripartum has been reported, however, to our knowledge, the case of ascending thoracic aortic aneurysm in peripartum women, with saccular type without aortic valve involvement but not diffuse dilatation, has not been reported. Herein, we presented two autopsy cases of ascending thoracic aortic aneurysm during postpartum.

Thyrotoxicosis (thyroid crisis) is a known cause of sudden death; however, only a few cases of death resulting from thyrotoxicosis have been reported. Histopathologic examination and postmortem thyroid function tests may be helpful in postmortem diagnosis, but their usefulness seems to be limited. We report three autopsy cases associated with thyrotoxicosis.

In the following report, we describe the case of a rapidly skeletonized corpse discovered in late summer. On the first day of September, a 57-year-old man was found almost completely skeletonized on a hill behind his house. His body lay prone, accompanied by a brush cutter at the entrance to the graveyard where his friend's parents were buried. His cap, clothes, and rubber boots were all intact and undamaged. Upon autopsy, no definite abnormalities were identified except for an old linear fracture on the frontoparietal bone. According to his friends and neighbors, he had likely died 8 or 9 days prior to the discovery of his body.

Here, we report an autopsy case of an unusual hanging that was misinterpreted as a case of homicidal strangulation, as th body was found on the scene of a house fire. A 29-year-old unmarried woman hanged herself from the gas pipe using a bath towel. Subsequently, the pipe broke and a fire broke out after an explosion. However, as the initial postmortem investigation revealed the absence of cherry-pink lividity and as a burnt bath towel was found around her neck, this case was misunderstood as a case of arson after homicidal strangulation. The cause and manner of death in this case were finally determined based on the autopsy findings of ligature marks that are typically noted in cases of hanging and the presence of a burnt electric lock and a broden gas pipe that were noted at the suicide scene.

Spinal dural arteriovenous fistula (SDAVF) is known for its ambiguous and various clinical presentations. Among these presentations, congestive myelopathy is one of the most common, yet it is challenging to correctly diagnose SDAVF at initial presentation. Several diseases present as myelopathy, including demyelinating diseases. Herein, we present two cases of congestive myelopathy due to SDAVF presenting to the emergency room (ER) with progressive quadriparesis. Even though the patients had a proper magnetic resonance imaging (MRI) examination from the initial presentation, there was a delay in making a final diagnosis. Both patients’ clinical presentation and MRI mimicked central nervous system (CNS) demyelinating disease initially, and a more thorough examination revealed SDAVF. Such a delay in diagnosis can result in more neurological deterioration and may result in more sequelae. Hence, SDAVF should always be considered as a differential diagnosis when examining patients with myelopathy.

Dural metastasis associated with chronic subdural hematoma is very rare in patients with malignant neoplasms; it may be difficult to distinguish malignant neoplasms from chronic subdural hematoma. Chronic subdural hematoma is usually a late manifestation of malignant tumors, which contributes to the severity of the prognosis. The scans obtained by using magnetic resonance imaging or computed tomography may be misleading when a subdural hematoma masks the underlying tumor. Herein, we report a case of a subdural hematoma with dural metastasis of unknown origin in a 45-year-old woman; however, the neoplasm was not detected until autopsy.

From January 2007 to June 2012, 55 autopsy cases were reviewed, in which death occurred outside the hospital and the patients were declared dead on arrival at the emergency departments, in order to compare the clinical and postmortem examination diagnoses of death-on-arrival patients in tertiary hospitals in Busan, Yangsan and Ulsan city. Of 22 non-traumatic deaths, 21 occurred from natural causes and 1 from unknown cause (sudden infant death syndrome, SIDS). Clinical diagnoses were cardiovascular diseases or "non-traumatic" / "unknown" while autopsy diagnoses were majorly cardiovascular diseases, especially coronary artery diseases (72.7%). Of 33 unnatural deaths, the cause of death was blunt trauma in 4 patients, sharp-force injury in 6, falling in 10, gunshot injury in 1, traffic accidents in 3, asphyxia in 2, drowning in 2, fire-related death in 1, and intoxication in 4. There were no definite discrepancies between clinical and autopsy diagnoses, except for 5 non-traumatic deaths and 2 unnatural deaths. These results suggest that the role of the emergency department may be crucial in postmortem investigations.

Esophageal foreign body impaction may be fatal secondary to occlusion of the glottis or external compression of the membranous portion of the trachea. A 14-year-old adolescent female was admitted to the emergency department for evaluation of sudden dyspnea and cyanosis after she swallowed a food bolus (a part of bachelor radish kimchi) without chewing. Unfortunately, the patient died despite cardiopulmonary resuscitation. Autopsy findings showed an ovoid, firm foreign body (3.5×2.5×2 cm) impacted in the proximal esophagus, with focal narrowing of the tracheal lumen secondary to external compression by esophageal foreign body impaction. Death was attributed to choking caused by an esophageal foreign body.
