RESUMEN
BACKGROUND: The aim of the present systematic review was to summarize evidence on odontogenic carcinosarcoma, analyzing clinical, epidemiological, imaging, histopathological, immunohistochemical, therapeutic, and prognostic features of this tumor. MATERIALS AND METHODS: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches were performed in the Ovid MEDLINE (Wolters Kluwer), PubMed (National Library of Medicine), Web of Science (Thomson Reuters), Scopus (Elsevier), and LILACS (Latin American and Caribbean Center on Health Sciences Information) databases, without publication date or language restrictions. Case reports or case series of OCS reporting clinical, radiological, and histopathological data that confirmed the diagnosis were selected. The Joanna Briggs Institute-University of Adelaide tool was used for critical appraisal of the included articles. RESULTS: Odontogenic carcinosarcoma is a rare, aggressive tumor associated with high mortality; however, the metastasis rate is low. The tumor has a male predilection. The mean patient age is 40 years, but there is no predilection for age. The left posterior mandible is the most affected site, but no specific radiographic features have been reported. CONCLUSION: Given its rarity, dentists, oral-maxillofacial surgeons, and physicians need to be aware of odontogenic carcinosarcoma in order to increase the diagnostic potential, preventing delays in diagnosis and treatment and thus contributing to lower morbidity of the tumor.

ABSTRACT: Surgical management of odontogenic infections in Sturge-Weber Syndrome is challenging, due to the risk of massive bleeding and difficulty to achieve hemostasis. The authors describe the use of preoperative vascular embolization for oral surgery in a 29-year-old patient. The authors highlight the importance of hemostatic agents and primary wound closure and the role of vascular embolization as a potential tool for preventing hemorrhage in these cases.

Aneurysmal bone cyst is a rare osteolytic lesion of uncertain etiology, commonly observed in the lower limbs, with only 1-2% of reports in gnathic bones. We present the case of a 27-year-old male patient referred to the oral and maxillofacial surgery and traumatology service due to complaints of paresthesia in the mental region and increased mandibular volume. Physical examination revealed midline shift and hard consistency. Imaging examinations demonstrated a radiolucent/hypodense lesion with disruption of the mandibular cortices. The histopathological examination of incisional biopsy material led to the diagnosis of a central giant cell lesion. The patient underwent surgical resection, and the histopathological analysis of the specimen revealed a predominantly solid lesion, characterized by blood-filled spaces of varying size, not covered by epithelium or endothelium, with the presence of spindle cells, multinucleated giant cells, and basophilic osteoid material, concluding the diagnosis of mixed-type aneurysmal bone cyst. Despite being uncommon, aneurysmal bone cysts should be considered in the differential diagnosis of volumetric increase in the gnathic bones of young patients.

Multiple myeloma (MM), solitary bone plasmacytoma, and extramedullary plasmacytoma are different types of plasma cell neoplasia, which is a lymphoid neoplastic proliferation of ß-cells. While MM is most frequently seen in the vertebrae and long bones, 30% of MM cases are found in the jaws. This case report presents a 58-year-old man with mandibular swelling; his medical history indicated he had a fracture of the humerus 1 month earlier. Panoramic radiography revealed a radiolucent lesion in the mandibular posterior region. Biopsy was performed and the histopathological examination indicated plasmocytoma. However, given the patient's dental and medical history, and the presence of multiple osteolytic lesions, the final diagnosis was MM. The patient underwent chemotherapy for the MM. To treat the pathological fracture of the jaw, a hemimandibulectomy was followed by the installation of a reconstructive plate.

Bars and steel wires are the most commonly used methods to achieve maxillomandibular fixation, although there are numerous alternatives described for this same purpose. In cases of edentulous candidates for the conservative treatment of facial fractures, none of the conventional methods can be instituted for maxillomandibular fixation. Fixation in such cases is achieved with the aid of the total dentures of the patient or the confection of splints, but these methods lead to eating and oral hygiene problems. This article reports the case of an edentulous patient with a comminuted mandible fracture treated with a rarely described technique in which intermaxillary fixation was achieved with titanium miniplates.

Background: Liposuction is one of the most commonly performed cosmetic procedures worldwide. Complications associated with submental liposuction are rare. However, when they occur they are significant and can cause disFiguring consequences. The objective of this study was evaluated complications from submentual liposuction in literature and description of clinical experience of complication after submentual liposuction. Material and Methods: At first, a scoping review was carried out online search with no time restrictions for complications after submental liposuction was performed in the databases Medline / PubMed, Embase, and Web of Science. The variables analyzed were: age, sex, type of esthetic procedure, anesthesia, complications, time after Procedure, treatment, follow-up care, and sequelae. Then, a case of a patient with submental hematoma after an aesthetic procedure for submental liposuction was described. Results: Firstly, 539 articles were selected, after application of the inclusion criteria, 4 studies were included. Most cases were female (8:1), with a mean age of 55.77 years. Postoperative complications were found, such as submental depression, submental edema, hypertrophic scar formation, scar contracture, cervical necrotizing fasciitis, Cervico-facial dystonia and transient facial nerve paralysis. The follow-up period for cases ranged from 3 to 12 months. The clinical case presented there was no sequelae. Conclusions: Submental liposuction requires the surgeon's attention. Anatomical knowledge, correct clinical and surgical management, diagnosis, and immediate approach to adverse situations are points that must be respected in this type of esthetic procedure to avoid more serious complications.(AU)
