The 2019 novel coronavirus disease (COVID-19) has spread worldwide, infiltrating, infecting, and devastating communities in all locations of varying demographics. An overwhelming majority of published literature on the pathologic findings associated with COVID-19 is either from living clinical cohorts or from autopsy findings of those who died in a medical care setting, which can confound pure disease pathology. A relatively low initial infection rate paired with a high biosafety level enabled the New Mexico Office of the Medical Investigator to conduct full autopsy examinations on suspected COVID-19-related deaths. Full autopsy examination on the first 20 severe acute respiratory syndrome coronavirus 2-positive decedents revealed that some extent of diffuse alveolar damage in every death due to COVID-19 played some role. The average decedent was middle-aged, male, American Indian, and overweight with comorbidities that included diabetes, ethanolism, and atherosclerotic and/or hypertensive cardiovascular disease. Macroscopic thrombotic events were seen in 35% of cases consisting of pulmonary thromboemboli and coronary artery thrombi. In 2 cases, severe bacterial coinfections were seen in the lungs. Those determined to die with but not of severe acute respiratory syndrome coronavirus 2 infection had unremarkable lung findings.

In July 2023, an in-house forensic neuropathology consultation pilot was established at the Helsinki office of the Forensic Medicine Unit, Finnish Institute for Health and Welfare. This offered an alternative to the previous practice of full outsourcing to a hospital neuropathology department. This paper aims to introduce the first year experiences of the pilot.

Purpose: Hypothermia occurs when core body temperature drops below 35 °C. The purpose of this review was to identify and analyze studies on the topic of hypothermia from an immunohistochemical perspective to determine robust markers of fatal hypothermia.
Methods: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines.

Enzootic nasal tumor virus 2 (ENTV2), the etiologic agent of enzootic nasal adenocarcinoma (ENA) in goats, is highly prevalent in China and causes significant economic losses to the goat industry. Here we describe the occurrence of ENA on a Dazu black goat farm in Chongqing City. At autopsy, nasal cavity masses were observed within the nose of an affected goat; histologically, the tumor was a nasal adenocarcinoma.

Objective: To examine the changes in dermal mast cells density in the mechanically injured skin and to evaluate the applicability of dermal mast cells density increase as an injuries vitality diagnostic criteria (serial examination, statistically processed results).
Material And Methods: 240 skin autopsy samples with mechanical injuries from 40 persons were divided to 3 groups (80 in each group): vital injuries, postmortal injuries, control non-injured samples. A routine histological examination using standard H&E stain and IHC with mast cells tryptase antibodies was performed consequented with histological slides full-format scanning and computer processing.
