JOURNAL FREE ACCESSWe describe a rare patient with mandibular gingival cancer in whom a pseudoaneurysm of the maxillary artery developed after segmental mandibular resection, including the region from the floor of the mouth to the pharynx, and neck dissection, followed by reconstruction using a metal plate and a rectus abdominis myocutaneous flap. A mass measuring 35×25×20 mm was detected at the inner side of the reconstruction plate on postoperative contrast-enhanced CT, and angiography was immediately performed to confirm that it was a pseudoaneurysm. The aneurysm was located in the maxillary artery and was treated by coil embolization. Pseudoaneurysms occurring in the head and neck region, which usually develop secondary to acute neck injury, are rare, and few cases of pseudoaneurysm involving the external carotid artery have been reported. However, the mortality rate associated with carotid artery aneurysms is estimated to be as high as 30％, and early imaging diagnosis and treatment are therefore important for preventing fatal complications.View full abstractDownload PDF (587K) -

JOURNAL FREE ACCESSMyoepithelioma is a rare tumor, accounting for less than 1.5％ of all salivary gland tumors. We report an extremely rare case of this tumor occurring in the oral floor.
The patient was 69-year-old woman with a painless swelling of the oral floor. The tumor, measuring 20 × 20 mm, was located on the right side of the mouth floor. The tumor was removed surgically under general anesthesia. Histologically, the tumor consisted of spindle-shaped cells and plasmacytoid cells associated with a relatively well demarcated myxoid and hyalinous matrix. No ductal structures were found in any part of the tumor. The pathological diagnosis was myoepithelioma. Follow-up 13 months after tumor resection indicated a good prognosis with no signs of recurrence to date.View full abstractDownload PDF (625K) -

JOURNAL FREE ACCESSThe incidence and mortality rate of tetanus have declined because of the development of vaccines, but tetanus remains a serious disease and can be fatal if treatment is delayed. We describe our experience with a case of tetanus in a 44-year-old man who visited our hospital because of trismus. The forcible mouth opening range was 5 mm. Although there was no apparent paralysis or dysesthesia, the patient complained of shoulder stiffness. When we contacted the patient four days after the initial examination, he experienced difficulty in walking. The patient was thus brought him to the emergency room of our hospital immediately. Tetanus was suspected on the basis of symptoms of dorsomesial rigidity in addition to trismus and a history of trauma involving his finger. Debridement of the affected area and tracheostomy to prevent possible dyspnea were immediately performed, and treatment with antitetanic human immunoglobulin was started. The patient’s condition was managed in the ICU by sedation and artificial ventilation in a dark room. On day 45 after the initial examination, remission of muscle rigidity was achieved, and the artificial ventilator was removed. The patient was discharged on day 73.View full abstractDownload PDF (486K)
