In such cases, death may result from thoracic or thoracoabdominal compression, airway obstruction by particulate material, massive inhalation of sand or soil, or a combination of these mechanisms. External signs may be subtle or absent, making postmortem interpretation highly dependent on a comprehensive, multilevel assessment. Case Presentation and Methods: We report the case of a 17-year-old male who died following accidental sand burial caused by the collapse of a self-excavated beach tunnel. External examination, autopsy, histological and toxicological analyses were performed. A review of the literature was also conducted to identify published forensic cases of fatal sand or soil burial and to compare circumstantial, macroscopic, microscopic, and ancillary findings. Results: Autopsy revealed marked pulmonary edema and congestion, multivisceral congestion, scattered sand granules within the larynx, and epicardial petechiae. Histological examination demonstrated acute pulmonary emphysema, edema, vascular congestion, and hemorrhagic laterocervical lymph nodes. Overall, the findings were considered most consistent with mechanical asphyxia due to thoracic compression. The literature review identified six eligible studies describing eight fatal cases. Despite the limited sample size and marked heterogeneity, two main diagnostic patterns emerged: compression-related deaths, usually associated with tunnel or beach-hole collapse and minimal or absent particulate material within the airways, and aspiration-\/obstruction-related deaths, characterized by abundant or compact sand or soil material within the airways. In cases without massive aspiration, mixed mechanisms may coexist. Pulmonary edema and congestion were the most frequently reported autopsy findings. When available, histological examination appeared useful in distinguishing antemortem from postmortem burial. Conclusions: Fatal sand burial should not be regarded as a uniform forensic entity. External examination alone is often insufficient, and accurate diagnosis requires a comprehensive, multidisciplinary approach integrating scene reconstruction, autopsy data, histopathological findings, and ancillary analyses. Hemorrhagic involvement of the laterocervical lymph nodes may represent a potentially relevant but currently underexplored finding, whose diagnostic significance warrants further investigation in analogous cases.<\/jats:p>","DOI":"10.3390\/diagnostics16111691","type":"journal-article","created":{"date-parts":[[2026,6,1]],"date-time":"2026-06-01T08:09:16Z","timestamp":1780301356000},"page":"1691","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Asphyxial Mechanisms in Sand Burial, Findings and Diagnostic Challenges\u2014A Case Report and a Literature Review"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6473-7632","authenticated-orcid":false,"given":"Donato","family":"Morena","sequence":"first","affiliation":[{"name":"Department of Anatomical, Histological, Forensic and Orthopedic Sciences, Sapienza University of Rome, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-3036-4014","authenticated-orcid":false,"given":"Anna Claudia","family":"Caruso","sequence":"additional","affiliation":[{"name":"Department of Anatomical, Histological, Forensic and Orthopedic Sciences, Sapienza University of Rome, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2452-7926","authenticated-orcid":false,"given":"Martina","family":"Padovano","sequence":"additional","affiliation":[{"name":"Forensic Science Police Service, Directorate for the Forensic Science Police and the Cyber Security, Department of Public Security, 00173 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7259-3090","authenticated-orcid":false,"given":"Matteo","family":"Scopetti","sequence":"additional","affiliation":[{"name":"Department of Medical Surgical Sciences and Translational Medicine, Sapienza University of Rome, 00189 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1686-3236","authenticated-orcid":false,"given":"Vittorio","family":"Fineschi","sequence":"additional","affiliation":[{"name":"Department of Anatomical, Histological, Forensic and Orthopedic Sciences, Sapienza University of Rome, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102617","DOI":"10.1016\/j.jflm.2023.102617","article-title":"Homicidal burial\u2014Forensic issues","volume":"100","author":"Byard","year":"2023","journal-title":"J.
