PubMed and Scopus databases were accessed to assess existing cases of oncological H&N malpractice. Twelve articles were identified according to search criteria in the selected period (2000-2024). Inclusion criteria lead to 6 articles pertaining to analysis of allegations of malpractice in H&N tumors. Diagnostic delay and informed consent issues are the most represented allegations. Poor access and lack of standardization in legal databases is commonly seen as a factor that holds back a thorough litigation analysis. This review adds evidence about common features of medical malpractice allegations through a medico-legal perspective that may help in adopting preventive strategies to mitigate risks and enhance patient safety.

FVM is a category of placental lesions consistent with restriction/interruption of fetal blood flow, frequently associated with a \"cord accident\".
