Epstein-Barr virus-positive mucocutaneous ulcer (EBVMCU) is a recently recognized B-cell lymphoproliferative disorder that is driven by latent EBV infection and causes discrete ulcerations in the oropharynx, gastrointestinal tract, and skin. A 56-year-old Japanese woman with a 1-month history of swelling in the right side of lower gingiva visited our hospital. The patient had a past medical history of rheumatoid arthritis (RA). She had been given a diagnosis of RA in 1981 and had received standard treatment with methotrexate (MTX) (8 mg/week) for more than 26 years (total dose, greater than 3840 mg). Following initial biopsy and withdrawal of the MTX, the area healed spontaneously over a period of several weeks. The morphological and immunophenotype features were in keeping with an EBV-related lymphoproliferative lesion consistent with EBVMCU. We requested discontinuation of methotrexate, and the lesion decreased and symptoms disappeared in 2 months. There was no evidence of recurrence 25 months after discontinuing methotrexate.

Low-grade central osteosarcoma, a rare subtype of osteosarcoma, is less aggressive than conventional osteosarcoma. We report ac case of low-grade central osteosarcoma of the mandible. A 52-year-old woman presented to our department for treatment of a swelling in the right side of the mandible. Computed tomography revealed ground glass radiopaque lesions associated with an expansive growth pattern in the mandibular bone. Because a suspicion of low-grade central osteosarcoma was diagnosed In the biopsy sample provided from the previous hospital, the lesion was surgically resected. Histopathologically, the tumor consisted of a dense proliferation of spindle cells with mild atypia. At the periphery of the lesion, the normal cortical bone was invaded by tumor nests. Low-grade central osteosarcoma was diagnosed in the surgical specimen. Tumor recurrence has not been observed for more than 6 years after surgery. Low-grade central osteosarcoma is hard to differentiate from osteogenic benign neoplasm or bone malformation. Therefore, when radiographic findings reveal an expansive ground glass appearance, a bone biopsy including the normal cortical bone and the central part of the lesion is essential.

Primary carcinoma arising in the dorsum of the tongue is very rare and may be erroneously diagnosed as a benign lesion.<BR>We present a case of squamous cell carcinoma of the dorsum of the tongue in a 49-year-old man. Intraoral examination revealed a tumor measuring 41×30×7 mm in the midline of the dorsum of the tongue. A biopsy was performed, and the diagnosis was squamous cell carcinoma. After preoperative chemotherapy, total resection of the tumor was performed. During about 1 year of follow-up, there has been no sign of recurrence or metastasis.

Fall in child is relative more as a course of injuries on tooth, gingiva, alveolar bone, lip, tongue and buccal mucosa in house. In adult, fall on walking, hits in sports and working accidents are most courses. Injuries of oral and maxillofacial region should be repaired correctively on short times to be anatomical tissue situation just before accident. It is good points to preserve the dislocated tooth as far as possible, to repair the bone fragments and to suture the muscle and epithelium correctively. Drainage is necessary on infected wounds. It needs to observe the color of tooth crown, absorption of tooth root-apex. We have to observe the development of mandible on child. Treatment of trigeminal and facial nerve injuries are usually dosage corticosteroids and vitamin B12.

It is beneficial for postdoctoral Japanese oral and maxillofacial surgery (OMFS) training to evaluate postdoctoral OMFS programs in other developed countries. Such studies should contribute to improving the quality of oral health in Japan. Currently there have been no research articles introduced for Japanese oral and maxillofacial surgeons that report on the postdoctoral OMFS training programs in the United States of America (USA). We therefore report the current status of oral and maxillofacial surgery training programs in the USA.Eleven topics are discussed. OMFS residency programs in the USA are speciality programs designed for oral and maxillofacial surgeons. Certification by the American Board of Oral and Maxillofacial Surgery is achieved after 4 to 6 years of training. A medical school curriculum is included in 46 of 102 OMFS residency programs. The average duration of the medical school curriculum was 28.4 months. Such curricula are designed to train OMFS residents who possess standard knowledge and techniques. The programs are strictly managed by a program director.

Congenital maxillomandibular fusion is a very rare congenital anomaly in which the maxilla (medial orbital wall or maxillary process) and mandible (mandibular process or lateral lingual swelling) adhere via bony or soft tissue. It is also called congenital maxillomandibular fusion or congenital syngnathia or congenital oral synechia, but is referred to as congenital maxillomandibular fusion in this paper. We describe a case that developed in a 2-day-old male infant with cleft lip and palate. He was born at 40 weeks, 4 days’ gestation and weighed 3046 g. The Apgar score was 8/9. His condition was diagnosed as lactation disorder, cleft lip and palate, and a funicular structure from the lower lip to palate at birth, and he was admitted to our department in Okinawa Chubu Hospital. We resected the funicular structure extending anteriorly from the left lower lip to the left incisive bone. To date, five kinds of desmoplastic attachment areas have been reported, which are the residual ridge interval, floor of mouth and hard palate, tongue and hard palate, tongue and soft palate, and lower lip and the hard palate. Cleft palate is the most commonly reported complication of congenital maxillomandibular fusion, and syndromes such as Van der Woude syndrome (cleft lip and palate, lower lip fistula), popliteal pterygium syndrome (cleft lip and palate, lower lip fistula, genital malformation, limb malformation, popliteal pterygium) have also been reported. Only two cases of congenital maxillomandibular fusion in which the palate adhered to the lower lip in association with popliteal pterygium syndrome have been reported. We recently encountered a patient with bilateral cleft lip and palate who had adhesion between the lower lip and hard palate, and report this case along with a review of the literature.

Traumatic carotid-cavernous sinus fistula (t-CCF) is an arteriovenous fistula formed by the tearing of the internal carotid artery running in the cavernous sinus, accompanied by head/maxillofacial injuries. Patients with this disease rarely show spontaneous closure and often require urgent endovascular treatment. We report a case of t-CCF that developed following jaw and zygoma fractures and was successfully treated by manual carotid compression. A 35-year-old man was referred to our hospital to undergo treatment for multiple maxillofacial fractures. On the first day after injury, open reduction and internal fixation of the mandible were conducted with the patient under general anesthesia. On the fifth day after injury, diplopia of the left eye suddenly appeared. On the seventh day after injury, left exophthalmos/edema of the left upper eyelid/left abducens nerve palsy/bilateral ptosis, and hyperemia of the bulbar conjunctiva appeared. On the 15th day after injury, cerebral angiography revealed a definitive diagnosis of t-CCF. Supervised manual carotid compression during the waiting period before endovascular treatment led to improvement in various symptoms from the 19th day after injury. Cerebral angiography, which was performed again for endovascular treatment, revealed that arteriovenous fistula resolved spontaneously. Therefore, treatment was discontinued, and the patient was followed up with a conservative approach. By 9 months after injury, all symptoms, including left oculomotor nerve palsy had disappeared. There was no evidence of recurrence 10 years after injury.

Guideline to prevent surgical site infection was published from Japanese society of surgical site infection and Japanese society of antibiotics chemotherapy in 2016. In the guideline, antibiotics prophylactic regimen has described in the all field of surgeries including oral surgery and dentistry. In 2018, Japanese society of cardiology published revised version of ‘Prevention and treatment of infective endocarditis (IE)’. In the guideline, antibiotics prophylaxis of IE in dentistry has described extensively. Since proper use of antibiotics for prevention of antimicrobial resistant bacteria production in oral surgeries has not been discussed sufficiently, we oral surgeons should understand the importance of proper antibiotics prophylaxis in oral surgery in accordance with these new guidelines.

Extraction of the lower third molars is a common procedure in oral surgery. After the procedure, disturbance of the lingual nerve is rare. In patients with mild injury, conservative treatment with drugs and stellate ganglion block may relieve symptoms. However, in severe cases, microsurgical treatment of the injured lingual nerve should be performed as soon as possible. We operated microsurgically in 3 patients with lingual nerve disorders that occurred after mandibular third molar extraction. After the operation, senses other than taste recovered in all patients, and taste was improved in 2 of the 3 patients. After the operation, 2 patients were satisfied, and the other was almost satisfied. No patient was dissatisfied. The concept for the management of such an iatrogenic lingual nerve injury remains unclear. In addition, we discuss treatment planning for iatrogenic lingual nerve injury

A case of pyostomatitis vegetans associated with ulcerative colitis is reported. A 57-year-old man with a history of ulcerative colitis was referred to our hospital because of pain in both sides of the buccal mucosa and malnutrition. A snail-track-shaped ulcer and miliary pustules with a cobblestone appearance were found in both sides of the buccal mucosa and soft palate. Treatment with topical corticosteroids had no effect on this lesion. The presence of abdominal pain and hematochezia led us to suspect a recurrence of ulcerative colitis. Immediately after the systemic administration of corticosteroids was started, the oral mucosal lesions resolved. This case suggests that treatment of ulcerative colitis with systemic corticosteroids is required to cure pyostomatitis vegetans.

We report a case of pyostomatitis vegetans associated with ulcerative colitis. The patient was a 25-year-old woman referred to our hospital because of irritative pain of the right side of the buccal mucosa. She had been receiving mesalazine for ulcerative colitis for 4 years. An erosion with a cobblestone appearance and a small ulcer were observed on the right side of the buccal mucosa. Histopathological examination showed subepithelial microabscesses containing lymphocytes and eosinophils in the subepithelial connective tissue. We finally diagnosed pyostomatitis vegetans associated with ulcerative colitis. The oral lesion completely disappeared 1 month after the administration of prednisolone.

<p>Clear cell odontogenic carcinoma (CCOC) was reclassified from a benign tumor to a malignant tumor by the WHO classification in 2005 because of its aggressive nature and potential for local recurrence and distant metastases. Only 81 well-documented cases have been reported to date to the best of our knowledge. A patient was referred to our clinic because of rapid swelling of the left side of the mandible. Computed tomography (CT) showed a bone defect in the mandible, but no cervical lymph node metastasis. We suspected a malignant tumor and performed a biopsy. We diagnosed CCOC of the left side of the mandible and performed segmental mandibulotomy. Histopathologically, the tumor consisted of clear cells containing diastase-digestive PAS-positive granules. Furthermore, immunohistochemistry showed that the tumor cells were immunoreactive for cytokeratins (CKs) 7, 17, 19, Ki-67 and vimentin, but non-reactive for CK20, smooth muscle actin (SMA), epithelial membrane antigen (EMA) and S-100 protein. The Ki-67 labeling index (LI) was 10%. We finally diagnosed CCOC. One year 5 months after surgery, the patient died of multiple organ failure caused by the multiple bone metastases. We discuss this rare case of multiple bone metastases developing from CCOC of the mandible and review the literature.</p>

Amyotrophic lateral sclerosis (ALS) is an incurable, progressive, and neurodegenerative disease specifically affecting both upper and lower motor neurons. It induces dysphagia, reduction of respiratory function, and limb muscle weakness, leading to aspiration pneumonia and respiratory insufficiency. ALS can be detected at dental visits on the basis of early oral symptoms such as dysphagia. However, there are few reports describing ALS in dental journals. We describe a man aged 59 years who visited our department because of functional changes, including decreased swallowing ability. Imaging studies demonstrated no tumor lesions, but tongue fasciculations were present. Videofluorographic evaluation revealed incorrect swallowing (aspiration) and food remaining in the larynx. We consulted the department of neurology in our university hospital. Because needle electromyography and other examinations ruled out other possible diseases, the patient was given a diagnosis of ALS. We made a palatal augmentation prosthesis to maintain deglutition function and followed up oral function. Oral symptoms of ALS are sometimes observed in its early stage. Therefore, oral surgeons and dentists need to possess adequate knowledge about this disease.

Malignant tumors rarely arise from jaws cyst. We report a case of squamous cell carcinoma arising from a nasopalatine duct cyst. A 70-year-old man presented with a swelling in the palatal gingiva at the middle of the maxilla. Oral examination showed a 28×25mm swelling with a puncture mark, asmooth surface, and normal color. Radiographic examination revealed a round translucent image measuring 15×12mm in diameter in the middle of maxilla. The image was clearly demarcated. Under general anesthesia, extirpation of the cyst was performed for a diagnosis of nasopalatine canal cyst. Histopathological examination of the resected specimens showed transition of histologically normal cystic epithelium to squamous cell carcinoma. After the first operation, partial resection of the maxilla was performed. Three months after the partial resection, left jugular lymph node metastasis was detected. Partial neck dissection, chemotherapy, and irradiation were performed. Twelve months after partial resection of the maxilla, right jugular lymph node metastasis was found. Radical neck dissection was performed.For 2 years 4 months, there was no disease recurrence. However, the patient died due of pneumonia on April 13, 2002.

Recently, the occurrence of methotrexate-associated lymphoproliferative disorders (MTX-LPD) in the oral area is reported one after another. We report a case of MTX-LPD of the maxillary gingiva associated with rheumatoid arthritis (RA). A 80-year-old man was referred to our clinic because of severe pain associated with a ulcer on the left side of the maxillary gingiva. On blood tests, soluble interleukin-2 receptor (sIL-2R) was high, and EBV infection was detected. The histopathological diagnosis was EBV-positive diffuse large B cell lymphoma (DLBCL). He had been receiving methotrexate for RA. We therefore requested discontinuation of methotrexate, and the lesion was decreased and symptoms disappeared. Examination after 21 months showed no evidence of recurrence.We reviewed reports documenting 17 cases of oral MTX-LPD in Japan. The age of onset was 40-84 years old, the male-to-female ratio was 4:13, and the methotrexate treatment period was 1-114 months. The affected sites were the maxillary and mandibular gingiva in 14 cases, the tongue in 1 case, and the mouth floor in 1 case. On histopathological classification, 14 cases were non-Hodgkin’s lymphoma, and 1 case was Hodgkin's lymphoma. As for the course of treatment, 11 cases had remission with cessation of methotrexate. Symptoms improved in 1-2 weeks, and lesions disappeared in 1-4 months.

Photodynamic therapy is a new therapeutic technique that utilizes a photosensitizer selectively localized in tumors and activated by exposure to laser light, resulting in tumor necrosis. Photodynamic therapy has proved to be effective in the treatment of early cancers of the lung, esophagus, stomach, and uterine cervix, and was approved by the Japanese goverment. We consider early oral cancers to be good candidates for photodynamic therapy. This report describes two cases of tongue carcinoma treated by photodynamic therapy.
