JOURNAL FREE ACCESSCarotid artery occlusion is rarely associated with injury of the head and neck. Difficulty may be encountered in the diagnosis and treatment of this condition. We describe our experience with a patient with a mandibular fracture caused by a work-related accident in whom emergency surgery was performed. Subsequently, carotid artery occlusion was confirmed on the discovery of a cerebral infarction.View full abstractDownload PDF (2175K) -

JOURNAL FREE ACCESSThe lining epithelium of odontogenic keratocysts is affected by various types of inflammatory stimuli. However, malignant transformation of the cyst is extremely rare. We report a newly diagnosed case of squamous cell carcinoma arising in an odontogenic keratocyst. A 52-year-old man was referred to our outpatient clinic because of a swelling in the labial-side gingiva of the maxilla. X-ray examination showed cyst-like radiolucent bone defects in the middle of the maxilla, with an impact tooth overlaying the lesion. The patient received radiotherapy to the oral region because of a malignant lymphoma.
The cystic lesion was enucleated. Histopathological examination of the surgical material revealed an odontogenic cyst with malignant transformation. The thick squamoid epithelium showed irregular epithelial ridges with various types of atypism. The lesion was attributed to malignant transformation of the odontogenic keratocyst. The patient has been followed up for 13 months without recurrence.View full abstractDownload PDF (1543K) -

JOURNAL FREE ACCESSErythroderma is a clinical syndrome characterized by erythema of the skin accompanied by variable degrees of infiltration and exfoliation. Erythroderma may result from different causes, including malignant tumors. Some reports suggest that erythroderma is a kind of paraneoplastic syndrome. Most erythrodermas accompanied by malignant tumors are associated with mesenchymal tumors. Association with epithelial tumors is rare. We report on a 60-year-old man with severely pigmented erythroderma associated with tongue carcinoma. He had a pruritic eruption on the legs in March 1999. The eruption worsened and spread over the entire body. The lesion was diagnosed as erythroderma and was unresponsive to corticosteroid therapy. He was referred to our hospital because of an ulcer and pain of the tongue. Intraoral examination revealed an indurative ulcer and adjacent leukoplakia on the left side of the tongue. Various examinations confirmed tongue carcinoma (T2N0M0). Partial tongue resection and skin transplantation from the inguinal region was performed in June 1999. After removal of the tumor, the skin condition began to improve gradually and almost resolved. The survival rate of the skin graft was about 30 %, and the inguinal region was cured uneventfully.View full abstractDownload PDF (1680K) -

JOURNAL FREE ACCESSA rare case of Ewing's sarcoma of the mandible is reported. A 50-year-old man was referred to our hospital because of right mandibular swelling and spontaneous pain. A biopsy specimen obtained by his dentist strongly suggested small round cell osteosarcoma. Since the tumor rapidly grew while preparing for chemotherapy, hemimandiblectomy and radical neck dissection were carried out with the patient under general anesthesia. Finally, a histopathological diagnosis of Ewing's sarcoma was made on examination of the surgical specimen. The patient was treated with adjuvant local irradiation (50Gy) and combination chemotherapy (VAIA, T-16). Although the primary lesion was well controlled, the patient died of multiple bone metastases 6 months later after the operation.View full abstractDownload PDF (2548K) -

JOURNAL FREE ACCESSNecrotizing sialometaplasia (NS) is a benign disease of the mucous-secreting glands that most commonly occurs in the palatal mucosa. It was first described by Abrams et al. in 1973 as an inflammatory disease characterized by coagulative necrosis of the minor salivary glands, marked squamous metaplasia of glandular acini and ducts, and even pseudoepitheliomatous hyperplasia. Etiologically, NS is thought to be caused by ischemia due to local tissue injury. We describe two cases of necrotizing sialometaplasia in a patient with bulimia and self-induced vomiting. The etiologic factors of NS are discussed. Initially, NS may be triggered by physical trauma with ischemia. Gastric juice irritation and side effects of drugs are considered to contribute to the development of NS.View full abstractDownload PDF (2640K) -

JOURNAL FREE ACCESSSymmetric lipomatosis is characterized by symmetric, tumor-like lipomatous proliferation of adipose tissue. This lesion usually develops in the head, neck, shoulders, and upper trunk; however, it is rarely recognized in the oral region. We report a case of symmetric lipomatosis of the tongue (SLT). The patient was a 67-year-old man. He was not obese. Symmetrical and diffuse swelling was bilaterally recognized at the border of the tongue. The tongue showed macroglossia. Tongue biopsy was performed on the right-side swelling. The diagnosis was lipomatosis. No any other surgical procedure was done because of the patient's general condition and lack of dysfunction of the tongue. The lesion showed no tendency to enlarge during 9 months after biopsy. Although the etiology of SLT remains unknown, this condition is thought to be associated with alcoholism, liver disorder, hyperlipidemia, and androgenic hormones. This patient had a history of alcoholism, hepatitis C, hepatocellular carcinoma, and an elevated serum triglyceride level. SLT in this patient was suggested to be associated with these metabolic disorders.View full abstractDownload PDF (1677K) -

JOURNAL FREE ACCESSTwo cases of supernumerary teeth in the nasal cavity are reported. Several reports have described ectopic teeth in the maxilla, but eruption into the nasal cavity is rare.
Case 1 was a 42-year-old woman with left nasal obstruction. A tooth mass was found in the left nasal cavity and was extracted via the nostril. The mass was a supernumerary tooth. After the operation, the patient's course was good, and the symptoms of nasal obstruction disappeared.
Case 2 was a 8-year-old girl who consulted a local otorhinolaryngology clinic because of aural pain. Intranasal fiberscopic examination disclosed a foreign body in the left side of the nasal cavity. Computed tomography showed that the foreign body was a tooth. Although the patient was scheduled for extraction of the supernumerary tooth, she had to change hospitals for family reasons.View full abstractDownload PDF (2130K) -

JOURNAL FREE ACCESSWe report a case of temporomandibular joint rheumatoid arthritis with perforation into the external auditory meatus.
The patient was 64-year-old man with progressive rheumatoid arthritis, associated with otopyorrhea and difficulty in mouth opening with pain. He had difficulty with the occlusion and was nearly edentulous jaw for a long time. He was also infected with MRSA in inflammatory granulation tissue in the meatus. He was treated with difficulty by an otorhinolaryngologist, who introduced him to our clinic.
We first made and applied dentures. Intermaxillary traction was applied by rigidly fixing the denture with an occlusal pivot to the jaw by means of an osseous screw and circumferential wiring. Antibiotics active against MRSA in the granulation tissue were given. After intermaxillary fixation for 2 weeks and intermaxillary elastic traction for the next 2 weeks, the TMJ space was enlarged and the granulation tissue in the meatus disappeard. Epithelialization successfully occurred. We finally attempted occlusal adjustment by raising the bite of the upper and lower dentures.
We fortunately treated the case successfully, but long-term observation is necessary.View full abstractDownload PDF (2168K) -

JOURNAL FREE ACCESSA case of Frey syndrome developing in the mandibular region after the removal of recurrent ameloblastoma including the submandibular gland is presented. The patient was a 63-year-old man who presented with gustatory sweating at the left mandibular region. He had undergone partial mandibulectomy and immediate reconstruction with alumina ceramics for an ameloblastoma arising in the left mandibular angle in 1986. The mandible was again reconstructed by iliac bone because of fracture of the alumina ceramics in 1987. The ameloblastoma recurred in the left submandibular region and was extirpated with the left submandiblar gland in 1995. After a few uneventful years, gustatory sweating developed at the left mandibular region in 2001. Frey syndrome of the left mandibular region was diagnosed by Minor's test. Frey syndrome in our patient was attributed to severe damage of the platysma and subcutaneous nerve due to repeated surgeries.View full abstractDownload PDF (2352K)
