RESUMO
Calcifying cystic odontogenic tumor (CCOT) is defined as an odontogenic cyst-like benign neoplasm that characteristically contains several ghost cells, ameloblastoma-like epithelium, and occasional calcification. Ghost cell odontogenic carcinoma (GCOC), a malignant form of CCOT, is an exceptionally rare malignant tumor. In this report, we present a case of a 53-year-old man whose chief complaint was a solitary mass on the right mandible area. The mass was completely removed through an extraoral surgical approach and reconstructive surgery was performed in two phases.

Two aged patients who had open tibial fractures with arterial injury caused by high energy accidents underwent emergency arterial reconstruction using a greater saphenous vein and soft tissue repair using free flaps. In the patients, soft tissue necrosis developed and tibias were exposed at postoperative third week. Follow-up angiography through the superficial femoral artery showed occlusion of the anterior tibial artery. The anterior tibial artery was reconstructed using the contralateral greater saphenous vein graft and the latissimus dorsi myocutaneous and rectus abdominis muscle free flaps were transplanted for repair of necrotic soft tissue. The reconstructed arteries showed good perfusion to the new free flaps until union of the tibias occurred. The patients were followed-up for 21 years and 17 years postoperatively, respectively. In management of open comminuted fracture of the tibia, injury of the arterial system must be ruled out by angiography in addition to evaluation of the degree of soft tissue injury.

PURPOSE: There have been few case reports regarding treatment plans for long-term, neglected scalp defects and calvarial defects with subdural abscess. The purpose of this case report is to present our experience with a free latissimus dorsi musculocutaneous flap for scalp and calvarial defects and to discuss flap options in comparison with a literature review. METHODS: A 60-year-old man who fell down from a four-story-height that resulted in a craniotomy in 1979; he visited our outpatient clinic for a chronic, purulent scalp and calvarial defects with unidentified artificial bone. The artificial bone was removed by a neurosurgeon and reconstructed with a free latissimus dorsi musculocutaneous flap. The deep temporal artery was used as a recipient artery. The postoperative flap status was excellent until the 6th day post-operation when the patient experienced a seizure, and an arterial insufficiency occurred at the flap probably due to an arterial spasm. Emergency exploration with arterial re-anastomosis was performed and the flap status was stabilized. RESULTS: Complete wound healing was achieved after 3 weeks without infectious and systemic postoperative complications. During the 6 month follow-up period, there were no complications. CONCLUSION: We suggest the latissimus dorsi myocutaneous free flap as a good treatment option for a chronic, purulent, complicated scalp with calvarial defect, as a well as treatment for an acute traumatic defect.
