ジャーナル フリーDynamic enhanced magnetic resonance (MR) images of 22 tongue squamous cell carcinomas (T2: 9 cases, T3: 7 cases, T4: 6 cases) were analyzed quantitatively. These tumors showed peripheral enhancement patterns. Enhancement patterns were compared between central and peripheral regions. Signal enhancement to noise ratios (SE/N) of the regions of interest (ROIs) located in the peripheral and central regions of the tumor were measured. In addition, maximum SE/N, the time of maximum SE/N, %-washout, and increase rate of SE/N were calculated. On the basis of tumor size and histopathological features, images were divided into the following groups: T2 group, T3 group, and T4 group, Grade 1 and 2 group (L-Gr.), and Grade 3 (H-Gr.) group. The variables described above were compared among the groups.
There were no statistically significant differences in maximum SE/N, time of maximum SE/N, or increase rate of SE/N among different tumor sizes. However, %-washout of the central region in the T2 group was lower than that in the T3 group. Although there was no distinct trend in the peripheral region, T3 and T4 tumors tended to have a poorer supply of contrast medium in the central region.
Histopathologically, low-grade tumors tended to show early enhancement in the peripheral region. However, in the central region, low-grade tumors showed a poorer supply of contrast medium.
Our results suggest that clinicopathological features correlate with enhancement patterns on dynamic MR images of tongue squamous cell carcinomas.抄録全体を表示PDF形式でダウンロード (2803K) -

ジャーナル フリーWe report a case of cleft palate in a child whose speech was improved by covering the raw surface of the base of a pharyngeal flap with a free buccal mucosal graft.
A 2-year-8-month-old girl with cleft palate was brought to our clinic because of speech disorders. She had undergone palatoplasty at 1 year of age, but the surgery resulted in wound dehiscence. Therefore, she underwent reoperation at 1 year 6 months. The scar on the palate was remarkable, and we observed a defect encompassing a wide area of the soft palate. There was no detectable movement of the soft palate during phonation. The distance from the edge of the palate to the posterior pharyngeal wall was lomm and remarkably wide.
We planned superior-based pharyngeal flap surgery combined with re-pushback at 4 years 6 months of age, but the raw surface of the pharyngeal flap was too wide. It was impossible to cover this area with tissue from the soft palate or pharynx. Therefore, we grafted free buccal mucous membrane to this area to prevent scar contraction.
Preoperatively, we recognized glottal explosive sounds in all consonants and severe hypernasality, but after 4 years she has acquired almost normal articulation.抄録全体を表示PDF形式でダウンロード (2283K) -

ジャーナル フリーWe report a case of retropharyngeal abscess arising from infection of the mucobuccal fold region. A 73-year-old woman with severe swelling of the face and dysphagia was referred to our hospital. On the basis of the clinical symptoms and CT findings, the patient was given a diagnosis of an abscess accompanied by gas production involving the masticator, parapharyngeal, and retropharyngeal space.
She was treated successfully by incision of the abscess and the administration of antibiotics. Multiple incisions were performed in the buccal region, and drains were placed in the masticator space. Thereafter, symptoms improved considerably. All drains were removed on the 18th postoperative day, and she was discharged 30 days after the onset.
Retropharyngeal abscess is a rare but serious condition of the phlegmon. Treatment consists of systemic antibiotic therapy combined with thorough surgical drainage.抄録全体を表示PDF形式でダウンロード (1360K) -

ジャーナル フリーWe report a case of tetanus.
A 78-year-old woman was referred to our hospital because of trismus. Physical examination showed severe trismus and stiffness of the masseter and temporal muscles. The patient had no noticeable history of trauma. On the next day, the symptoms intensified. Tetanus was diagnosed on the basis of clinical course and symptoms such as trismus, facial grimacing, and stiffness of the masseter and neck muscles. The patient was immediately admitted to the intensive care unit. She was given antitetanic human immunoglobulin, tetanus antitoxin, antibiotics, dantrolen, and midazolam. Opisthotonus, airway obstruction, and circulatory disturbance did not occur. The patient recovered without tracheotomy or tracheal intubation.
Tetanus is a fatal infectious disease, if early treatment is not appropriately performed. We should consider the possibility of tetanus when examining patients with trismus and observe them carefully.抄録全体を表示PDF形式でダウンロード (2218K) -

ジャーナル フリーAn accessory parotid gland, usually located anterior to the main parotid gland, occurs in 20% to 60% of humans. However, tumors arising in accessory parotid glands are rare. We report a case of an accessory parotid gland tumor and review the relevant literature.
In 1999, a 79-year-old woman presented with a mass arising in the right cheek. The mass was noted by the general surgeon at our hospital. Dissection of a right cheek mass had been performed by another surgeon in 1984, but we were unable to obtain further information. The mass in the right cheek recurred in 1989 and had slowly grown since that time. The mass was pathologically diagnosed as adenoma on fine-needle aspiration, and the patient was referred to our department. A computed tomography scan of the head showed a subcutaneous mass measuring 2.0×3.0cm, located on the masseter muscle and anterior to the main parotid gland. The tumor was removed through a wide parotidectomy-style approach modified by extension of incisions anterosuperiorly and inferoanteriorly. The mass was 1.5cm anterior to the main parotid gland. The zygomatic and buccal branches of the facial nerve and parotid duct adhered to the mass, but there were no complications, such as permanent facial paralysis or salivary fistula. A routine pathological examination showed the presence of pleomorphic adenoma.抄録全体を表示PDF形式でダウンロード (2532K) -

ジャーナル フリーA 76-year-old man presented with swelling of the right side of the maxilla. Spindle cell sarcoma was diagnosed on examination of a biopsy sample of the right maxillary sinus. We started CYVADIC (cyclophosphamide, vincristine, adriamycin, dacarbazin) chemotherapy. A favorable clinical response was obtained with 4 courses of chemotherapy. Partial resection of the maxilla was followed by 6 courses of CYVADIC therapy, because a small residual tumor was suspected. Histopathological examination revealed no residual tumor cells.
Chemotherapeutic intervention appears to have been effective, with no apparent recurrence of lesions at present, 14 years after chemotherapy.抄録全体を表示PDF形式でダウンロード (2172K) -

ジャーナル フリーA case of adenosquamous carcinoma occurring on the floor of the mouth is presented. An 85-year-old man was referred to our clinic because of pain of the right sublingual region. Clinical examinations revealed a papillary tumor 17×9mm in diameter on the floor of the mouth. The histologic diagnosis of a biopsy specimen was well differentiated squamous cell carcinoma. The patient underwent tumor excision.
Histological examination of the surgical specimen showed both squamous cell carcinoma and adenocarcinoma. Adenocarcinoma-like lesion of the tumor showed positive veaction to PAS and Alcian blue staining, and the tumor was finally diagnosed as adenosquamous cell carcinoma. The patient is free from the disease 12 months postoperatively.抄録全体を表示PDF形式でダウンロード (8433K) -

ジャーナル フリーWe report a case of central giant cell granuloma arising at the ramus of the mandible. The patient was a 12-year-old boy with a painless buccal swelling. Computed tomography (CT) and magnetic resonance imaging (MRI) showed comparatively clear and limited bone resorption at the ramus of the right side of the mandible. Histopathological examination of a biopsy specimen revealed a granulomatous lesion. The lesion was enucleated completely under general anesthesia. The enucleated specimens pathologically showed multinuclear giant cells in granulomatous tissue with inflammatory cells. Giant cells were not distributed uniformly and were abundant around the foci of hemorrhage. The interstitium was rich with microvascular vessels and osteoid formation was present in some regions. The diagnosis was giant cell granuloma. The postoperative course was uneventful, and no recurrence is evident nearly 26 months after operation.抄録全体を表示PDF形式でダウンロード (2545K) -

ジャーナル フリーWe encountered a patient in whom remitting seronegative symmetrical synovitis with pitting edema (RS3PE) developed after treatment with UFT. A 64-year-old man who had cervical and lung metastases of unknown origin was treated with docetaxel hydrate, cisplatin, and 5-fluorouracil. Subsequently, the patient received UFT at a dose of 300 mg/day. Shortly after starting treatment with UFT, symmetrical pitting edema developed in the dorsum of the hands and feet. Since the results of immunological examination were consistently negative for rheumatoid factor, the patient was given a diagnosis of RS3PE. The symptoms of RS3PE markedly improved after the withdrawal of UFT and the start of steroid therapy. The findings suggested that UFT may be related to the development of RS3PE.抄録全体を表示PDF形式でダウンロード (2058K)
