Hooliganism and maxillofacial trauma: The surgeon should be warned.

INTRODUCTION: With more than 270 million spectators, football - or soccer - is the most popular sport in the world. International football events generate many risky situations, including hooliganism and are an opportunity to analyze the incidence and the particularities of associated trauma. We sought to underline the potential rapid and brutal increase in maxillofacial trauma during a world-class competition. MATERIAL AND METHODS: A retrospective multicenter study of the epidemiology of maxillofacial traumas during the UEFA 2016 Cup was conducted. All the medical data from each UEFA 2016 World Cup matches from 10 June 2016 to 10 July 2016 were collected. Only the maxillofacial traumas requiring a surgery under general anesthesia and a hospitalization were included. RESULTS: 11 patients from 3 different cities were included. The main etiology was interpersonal violence (7/11), followed by road accidents (3/11). Open reduction with internal fixation of a mandibular fracture was the most performed surgery (9/11). Patients were 18 to 50 year-old, with an average age of 30.6 years. DISCUSSION: This study underlines the violence of riots between "ultra" supporters during the 2016 UEFA cup. We noticed an upsurge of maxillofacial trauma severe enough to require a surgery under general anesthesia. Hooligan behaviors should be known by every practitioner dealing with trauma care, and may requires transitional adjustment of public health policy.

A rare case of oral metastasis of colon adenocarcinoma.

INTRODUCTION: Metastatic carcinoma of the colon is frequently encountered. In the literature, metastasis of malignant tumors in the buccal cavity are rare. They represent less than 1% of oral malignant lesions. OBSERVATION: We present a case of oral metastasis of colon adenocarcinoma in the mandible of a 62-year-old patient. The physical examination revealed a swelling in the mandibular symphysis associated with dental displacement. The panoramic X-ray showed significant bone lysis of the symphysis. The neoplastic tissue showed marked positivity for Cytokeratin 20 and CDX2, confirming the diagnosis of metastasis of the oral cavity from colorectal adenocarcinoma. DISCUSSION: Metastatic adenocarcinoma from the colon to the oral cavity are rare but should be included in the differential diagnosis of tumors in the oral cavity.
