Intracranial lipomas are rare benign tumors considered exceptional when localized in the cerebellopontine angle (CPA), with an incidence of 0.1% of the total number of expansive processes located in this area. We present a case of the sudden death of a 26-year-old young woman in which an unencapsulated neoformation of 0.8 cm was documented at the right cerebellopontine angle and was histologically characterized as intracranial lipoma. The cause of death was then identified as a cardiocirculatory failure secondary to supratentorial (uncal right) herniation caused by the lipoma of the pontocerebellar angle with high-grade diffuse cerebral edema., Competing Interests: Conflict of interest: None., (Copyright © 2022 The Author(s).)

Varix of the lower extremities is a common entity that eventually presents fatal outcome. Fatal massive bleeding due to rupture of a peripheral varicose vein is rare. The estimated incidence of these cases is 1/1000 autopsies. The case we present is unique among 26,054 autopsies performed in Milan from 1993 to 2020. It describes the investigations carried out in the suspicion of a non-natural event in an elderly woman. She was found dead at home with a large volume of blood near her feet that drained from the right leg. Pathological examination disclosed that the hemorrhage occurred by the rupture of a venous varix of the lower limb. Cases of fatal hemorrhage from peripheral variceal rupture are insidious and require proper characterization. The bloodstain pattern analysis, careful autopsy dissection by layers to demonstrate the rupture, and histologic examination of the lesion are the essential elements to find out the actual cause of death., Competing Interests: Conflict of interest: None, (Copyright © 2021 The Author(s).)

The effective value of microbiological post-mortem examinations stands as fundamental in forensic cases involving microbiology. We ran these analyses on five victims, who suddenly died after showing persistent fever. The examinations were conducted between 48 hours and 10 days after death, and adrenal gland apoplexy was detected in all the cases. Microbiological examinations identified Neisseria meningitidis , which was accountable for Waterhouse-Friderichsen syndrome. Diplococci were isolated from three cadavers that underwent forensic dissection between 2 and 3 days after death. The remaining two cadavers showed polymicrobial contamination, and a polymerase chain reaction technique was necessary to identify the pathogen. We assumed that the microbial overlap could lead to diagnostic mistakes and conceal the identification of the lethal pathogen. Therefore, we suggest using molecular techniques for a postmortem interval (PMI) longer than 72 hours. Classical microbiological examination should be performed for PMI within 72 hours., Competing Interests: Conflict of interest: None

Pulmonary thromboembolism (PTE) is one of the major complications in oncologic patients. The incidence of PTE in these cases is 4 to 7 times higher than in non-oncologic patients. Ovarian tumors, specifically those of large sizes, may impair the blood flow through the pelvic veins as tumor pressure over the pelvic vessels increases the incidence of thrombosis. The authors report the case of the unexpected death of a 74-year-old female due to massive pulmonary thromboembolism, associated with an ovarian tumor almost of 15 kg of weight that filled the abdominal and pelvic cavities. The compressive effect on the walls of the pudendal and periuterine veins somehow facilitated the local thrombosis. According to the histological characterization on post-mortem samples, the mass was identified as an "atypical proliferative (borderline) mucinous tumor." The case emphasizes the important association between pulmonary thromboembolism and ovarian tumors., Competing Interests: Conflict of interest: None
