ジャーナル フリーMyoepithelial carcinoma (MEC) ex pleomorphic adenoma (PA) is defined as a rare malignant myoepithelial neoplasm arising from a primary or recurrent benign pleomorphic adenoma. We report a case of MEC ex PA in the buccal region of a 93-year-old woman. The patient was referred to our hospital because of a mass in her left buccal region. Intraoral examination revealed a protruding mass measuring 25 mm on the left buccal mucosa. MR revealed a well-defined, 47 × 31 × 28 mm lesion in the left buccal area, with inhomogeneous high intensity on T2-weighted images. A biopsy of the tumor suggested a salivary gland tumor, however accurate preoperative diagnosis was difficult. The patient underwent enucleation of the tumor under general anesthesia. The final pathological diagnosis was MEC ex PA. Most of the tumor consisted of MEC, however PA was also observed. Four years and nine months post-operation, the patient has shown no evidence of recurrence or metastasis.抄録全体を表示PDF形式でダウンロード (4193K) -

ジャーナル フリーIn the oral and maxillofacial region, epidermoid cysts most commonly occur in the sublingual floor of the mouth. They are rarely seen initially in the oral region of infants and neonates. In this report, we describe a case of multiple congenital epidermoid cysts in the tongue of a fetus. The patient was delivered via ex-utero intrapartum treatment at 37 weeks and 5 days of gestation. Cystic lesions were detected on the tongue during a fetal ultrasonography, and there was a risk of postnatal airway obstruction. Therefore, the patient underwent endotracheal intubation and was managed in the NICU. CT showed three cystic lesions in the tongue, each measuring 10-20 mm. On the 8th day after birth, the cysts were resected through the midline sagittal glossotomy under general anesthesia. The final histopathological diagnosis was epidermoid cyst. The postoperative course was good with no recurrence. Fetal tongue mass lesions are associated with the risk of airway obstruction and dysphagia, potentially affecting later growth and development. Accurate diagnosis and early treatment in collaboration with related departments are important.抄録全体を表示PDF形式でダウンロード (2314K) -

ジャーナル フリーBypass therapy has been the main hemostatic treatment for patients with hemophilia A with inhibitor. Emicizumab, approved in 2018, is rapidly becoming widespread due to its long half-life, low frequency of administration, convenience of subcutaneous route of administration, and high efficacy in preventing bleeding. We performed perioperative management of a 71-year-old man with severe hemophilia A with inhibitor who underwent multiple tooth extractions. Before using emicizumab, we infused a bypassing agent for several days, and it took 8-15 days to stop the bleeding. After using emicizumab, the number of additional infusions was reduced and the hemostasis period was shortened to 2-6 days. The administration of emicizumab was thought to have reduced the likelihood of post-extraction bleeding.抄録全体を表示PDF形式でダウンロード (1132K) -

ジャーナル フリーAn intranasal ectopic tooth is a rare clinical entity, and can present as a cause for nasal obstruction and chronic rhinosinusitis. Surgical removal is recommended to eliminate the symptoms. On the other hand, calcareous concretions in the nasal cavity are called rhinoliths. They are generally considered to occur due to inorganic salts accumulating around a nidus over time. However, there are also cases not involving niduses. Chronic inflammation occurring around the nidus and bacterial infections are factors that cause formation of rhinoliths. The symptoms of rhinoliths are nasal obstruction, rhinorrhea, nasal malodor, and nosebleeds. There are few reports of nasal tooths with a rhinolith. We describe a case of intranasal supernumerary tooth with a rhinolith. A-61-year-old a man was admitted to otorhinolaryngology with the chief complaint of nasal odor. A rhinolith was observed near the inferior turbinate in a nasopharyngeal endoscopy, and CT images showed a supernumerary tooth in contact with the rhinolith. The rhinolith was extracted with a nasal endoscope, and the supernumerary tooth was extracted via an oral approach under general anesthesia. One year has passed since the operation, and no rhinolith recurrence has occurred.抄録全体を表示PDF形式でダウンロード (3568K) -

ジャーナル フリーLocal control of head and neck cancer is particularly important to preserve cosmetic and functional aspects and to maintain quality of life, however there is no established treatment for unresectable recurrent cancer after standard treatment. In this report, we describe a case of head and neck Alluminox therapy, a promising new treatment modality. The patient was an 85-year-old woman. She was diagnosed with right maxillary gingival cancer and underwent multiple resections and chemoradiotherapy, however the cancer recurred in the right buccal mucosa. After the treatment, tumor shrinkage and pain reduction were observed, and the patient was transferred to home care. No serious side effects were observed. Head and neck Alluminox therapy is expected to be an effective treatment for unresectable locally advanced or recurrent head and neck cancer. In this case, pain management and tumor shrinkage improved the patient’s quality of life, suggesting the appropriateness of head and neck Alluminox therapy in the terminal stage.抄録全体を表示PDF形式でダウンロード (2563K) -

ジャーナル フリーExtranodal NK/T-cell lymphoma, nasal type, accounts for less than 3％ of all malignant lymphomas in Japan, and is rarely reported in the field of oral lesions. In this report, we describe a case of extranodal NK/T-cell lymphoma, nasal type, which was suspected to be focal myositis of the masseter muscle.
The patient became aware of discomfort in the right mandibular angle. She was diagnosed with focal myositis of the masseter muscle in the Department of Oral Surgery of another hospital, and received steroid therapy. The swelling worsened and she was referred to our department. No abnormal findings were found in the oral cavity or jaw that could have caused the swelling of the masseter muscle, so the patient was placed under observation. Six months after the initial visit to our department, the swelling worsened again, and steroid therapy was not effective. A muscle biopsy was performed under the diagnosis of focal myositis, and the histopathological result was extranodal NK/T-cell lymphoma, nasal type. Chemotherapy was commenced, followed by a cord blood transplantation. Four years after the initial visit, she is in good general condition with no recurrence.抄録全体を表示PDF形式でダウンロード (2380K)
