Benign odontogenic neoplasms are rare, but malignant odontogenic neoplasms are extremely rare. The majority of malignant epithelial neoplasms occurring in the jaws are the result of metastasis from distant primary neoplasms of direct invasion from contiguous carcinoma of the oral mucosa, sinus mucosa, salivary gland or skin. A few remaining primary intraosseous carcinoma of the jaw are presumed to be of mostly odontogenic origin since epithelial remnants of odontogenesis are numerous in the maxilla arts mandible. Although calcifying odontogenic cyst(COC) is a well-established pathologic entity, it has been recognized that there is an odontogenic neoplasm with histologic features similar to the COC(malignant epithelial odontogenic host cell tumor; EOGCT) that has been diagnosed as COC. Some authors have reported previously in the literature describing malignant EOGCT. We experienced one case of malignant EOGCT with aggressive growth pattern and histologic features strongly implying its malignant potential. The lesion was excised by anterior mandibular resection, total 1 resection of the tongue and bilateral functional neck dissection. The tongue was reconstructed by using the infrahyoid muscle neurovascular island flap and neurovascular radial forearm free flap. The mandible was reconstructed by using the osteocutaneous fibular free flap.

Laparoscopic repair using mesh is a standard technique for ventral hernia repair. Complications of laparoscopic ventral hernia repair increase according to the increment of laparoscopic repair. Subcutaneous emphysema and mesh infection are major complications of laparoscopic repair of ventral hernia. The principle of management of infection is removal of a foreign body. However, in the case of repair with mesh, removal of infected mesh induces recurrence of hernia. Preservation of mesh is the best option for treatment of infected mesh. We have experienced treatment without removal of mesh in a case of infected subcutaneous emphysema after laparoscopic ventral hernia repair. The infection spread slowly to mesh and seroma. Drainage and debridement of infected tissue and evacuation of infected seroma resulted in healing of the infection without removal of mesh.

Local or distant flap surgery has been applied in the soft tissue defect area where bone and tendon are exposed, but there are many pitfalls in these surgeries including limitation of donor site selection, as well as functional and aesthetic dissatisfaction of the donor and recipient site. So these problems have facilitated the development and study of skin substitute (artificial dermis). The history of artificial skin began in the 1980s with the invention of Stage I membrane by Yannas and Burke. Since then it has been developed and applied to chinical cases of extensive burn injury and soft tissue defect. In 1989, and artificial dermis (Terudermis) composed of fibrillar collagen and heat denaturated atelocollagen was developed by Konish. It has the advantage of allowing early-incorporation of cellular and vascular components into its collagen sponge, as well as dehydrothermal cross-linking, which is very weak. This study included 18 consecutive cases which underwent application of artificial dermis on bone and tendon from January 1997 to November 1998. The exposed areas were the result of trauma in 10 cases, postoperative complications in 2 cases, and other causes in 6 cases. The follow-up period ranged from 3 months to 18 months, averaging 11 months. A week after wound debridement and Terudermis application, neovascularization had begun and granulation tissue appeared aften 2-3 weeks. Then the split or full -thickness skin graft was secondarily applied resulting in the production of sufficient skin. In conclusion, Terudermis application to an area of exposed bone and tendon is a very useful method, especially when primary local or distant flap surgery cannot be used. This method is very simple, convenient and reliable.

Emphysematous urinary tract infection is a rare, life-threatening necrotizing infection characterized by gas generation, and usually occurs in patients with diabetes and/or urinary tract obstruction. We herein report a unique case of emphysematous renal infection occurred in. an old diabetic man with renal cell carcinoma. This case suggests that renal cell carcinoma should be also considered a rare cause of emphysematous renal infection showing mass contour.

Trauma, especially hemorrhagic injury, remains a leading cause of morbidity and mortality worldwide. Prompt and effective management of these injuries is essential to improve patient outcomes.Current Concepts: Damage control surgery (DCS) has become a crucial approach for managing patients with severe traumatic hemorrhagic shock. DCS prioritizes physiological stabilization rather than definitive anatomical repair, initially focusing on controlling the hemorrhage and preventing further complications. This strategy is pertinent in patients with polytrauma, in which immediate surgical interventions can help mitigate the lethal triad of hypothermia, acidosis, and coagulopathy.Discussion and Conclusion: The implementation of DCS involves rapid identification of bleeding sources, followed by temporary measures, such as packing and revascularization. Advanced techniques, including resuscitative endovascular balloon occlusion of the aorta and preperitoneal pelvic packing, have further enhanced hemorrhagic control in complex pelvic fractures and intra-abdominal injuries. These methods enable surgeons to promptly stabilize critically injured patients while preserving the options for definitive surgery after initial resuscitation. DCS represents a paradigm shift in the management of traumatic hemorrhage, emphasizing the need for timely intervention and effective resource allocation in trauma care. By understanding and applying the principles of DCS, healthcare providers can improve the survival rates of patients with trauma and lifethreatening hemorrhages.
