    It is extremely rare for a deciduous tooth to be displaced into the maxillary sinus during exodontia. We report the case of a second deciduous molar palatal root that was displaced into the maxillary sinus. The patient was a 13-year-old girl. During deciduous tooth extraction by a local dentist, the fractured root was displaced into the maxillary sinus. The patient was referred to our hospital. Radiographic examination and CT scanning showed that the displaced tooth root was located on the upper part of the medial surface of the maxillary sinus. Under local anesthesia, the displaced tooth was removed via the canine fossa. There has been no sign of inflammation of the maxillary sinus.

    Fungal infection of the paranasal sinuses was considered a rare disease in healthy people, but such cases have increased recently because of the use of antibacterial agents, steroid hormones and anticancer drugs. We report a case of aspergillosis of the maxillary sinus after Le Fort I osteotomy.
    The patient was an 18-year-old woman in whom mandibular prognathism with facial asymmetry had been corrected by Le Fort I osteotomy and bilateral sagittal split osteotomy. She complained of mild tenderness of the left cheek 3 months after surgery. Postoperative computed tomography showed diffuse radiopacity and a foamy low density area in the left maxillary sinus. Under general anesthesia, the thickened mucosa and necrotic tissue at the bottom of the maxillary sinus were surgically removed. Histopathological examination revealed the presence of sinus aspergillosis. The postoperative course has been good, with no evidence of recurrence.
    In this case, alterations of shape and volume of the maxillary sinus associated with Le Fort I osteotomy were considered to have triggered the development of aspergillosis.

    In the oral cavity, epidermoid cysts usually arise in the oral floor and rarely occur in the upper lip. A case of an epidermoid cyst of the upper lip is reported. The patient was a 22-year-old man. A cyst arising in the left side of the upper lip was diagnosed by the patients former doctor, and the lesion was extirpated under local anesthesia 1 year 7 months ago. However, 6 months ago, a painless mass developed slowly on the left side of the upper lip. Palpation, revealed a large movable mass. MRI and ultrasonic examinations showed that the lesion was 25mm in diameter in the subcutaneous tissue of the left side of the upper lip. The lesion was round and homogenous inside. We diagnosed the lesion to be a cyst of the upper lip and extirpated the mass under general anesthesia. The excised material was 20×10 mm in diameter and filled with a yellowish white serous liquid and a yellowish white cheese-like material. The specimen was histopathologically diagnosed to be an epidermoid cyst. Two years after the operation, the left side of the upper lip has healed and there is no evidence of recurrence.

    We report the case of a large sublingual cyst-like lesion that could not be diagnosed histopathologically because of marked long-term degeneration. The patient, a 62-year-old man, noticed a mass in the oral floor during childhood. However, the mass was untreated for over 50 years. At presentation, there was a 40×35mm mass in the center of the sublingual region. The mobility of the tongue was remarkably limited. The patient complained of mild mogiarthria and dysmasesis. MRI showed a well-delineated cystic lesion located above both the mylohyoid muscle and the geniohyoid muscle in the sublingual region. After the lesion was extirpated under general anesthesia, both mogiarthria and dysmasesis improved substantially. The wall of the lesion was thick, and the contents were a muddy greenish brown color. Histopathological examination suggested that the lesion was an extravasation mucous cyst or a thyroglossal duct cyst. However, a definitive diagnosis could not be made because the contents of the lesion changed remarkably. This case was thought to be very rare because the lesion was considered to have degenerated due to secondary effects during an extremely long period.

    A case of sebaceous lymphadenoma occurring in the parotid gland of a 54-year-old man is described. The chief complaint of the patient was a circular painless swelling in the front of the right tragus, present for several months. After we made an initial diagnosis of a benign tumor of the right parotid gland on the basis of MRI and ultrasonography, we performed a superficial parotidectomy to resect the mass. Histologically, the tumor was well encapsulated and consisted of ductal structures and cystic structures of squamous epithelium with focal but apparent sebaceous differentiation in a background of a lymphoid stroma. Histological examination revealed sebaceous lymphadenoma. Primary sebaceous neoplasms of the salivary glands are extremely rare. We found only 30 cases of sebaceous lymphadenoma, including our case, reported in and outside of Japan.
    The postoperative course was good, with no signs of recurrence for 2 years 6 months after operation.

    Multiple endocrine neoplasia (MEN) is a neoplastic disorder affecting multiple endocrine organs. MEN 2B is characterized by the occurrence of medullary thyroid carcinoma (MTC), pheochromocytoma, multiple mucosal neuroma, ganglioneuromatosis of the intestinal tract, and Marfanoid habitus.We report a rare case of MEN 2B diagnosed on the basis of multiple mucosal neuromas in the oral cavity.A 10-year-old boy was referred to our department for the evaluation and treatment of a tumor of tongue and lips. Under local anesthesia, the patient had undergone resections several times. Histopathological examinations of all resected tissues revealed mucosal neuroma. Because the results strongly suggested MEN 2B, long-term observation was done. When the patient was 14 years old, the disease was confirmed as MEN 2B on genetic analysis of the RET proto-oncogene. After the occurrence of MTC, total thyroidectomy and neck dissection were carried out under general anesthesia. The patient has been followed up, without recurrence. Because multiple mucosal neuromas of the upper lip and tongue grow intermittently, we have resected the lesions as necessary.

    Metastatic tumors of the oral region are rare and comprise approximately 1% of all malignant oral tumors. To our knowledge, only one case of metastatic eccrine porocarcinoma of the oral cavity has been described previously. We report an extremely rare case of eccrine porocarcinoma that metastasized to the upper gingiva. A 69-year-old man who had underwent an operation for eccrine porocarcinoma of the back was referred to our department because of an upper gingival tumor on the right side. At presentation, he already had systemic skin metastases from eccrine porocarcinoma, including the facial skin.
    Intraoral examination revealed a 30mm×20mm hard submucosal mass. The tumor was excised and showed histological features similar to that of the back tumor. Therefore, the tumor was diagnosed to be a metastatic eccrine porocarcinoma of the upper gingiva. Finally, 8 months after the operation at our department, the patient died of multiple organ failure due to systemic metastases.

    We report a case of 77-year-old woman with focal oral mucinosis (FOM) arising in the hard palate. The patient had noticed a nodular mass 8 years earlier and over this period she felt that it had gradually grown. The mass was 20mm in diameter, painless, and had a smooth surface. Magnetic resonance imaging of the lesion revealed high signal intensity on T2-weighted images. Because biopsy suggested a benign non-epithelial tumor, the tumor was resected under general anesthesia. Histological examination showed that the lesion consisted of well-localized myxomatous connective tissue. The tissue was stained with alcian blue, which disappeared after hyaluronidase digestion, indicating an abundance of acidic mucopolysaccharides. The fibroblast-like cells with mucin retention were immunohistochemically negative for S-100 protein. Finally, a review of diagnoses of FOM is presented.

    Reports of abnormalities in hemostasis after minor surgery, especially after the extraction of teeth in patients with disseminated intravascular coagulation (DIC), are rare. This report presents a case of chronic DIC associated with an aneurysm, leading to hemorrhage after the extraction of a tooth. The patient was an 81-year-old man with a history of hepatitis C, atrial fibrillation, and aneurysms. We performed local hemostatic treatment, but intermittent hemorrhage continued. On investigating the cause of the persistent hemorrhage, we found a distinct rise in fibrinogenolysis markers and an increase in a thoracic aortic aneurysm. Chronic DIC of fibrinogenolysis predominant type was therefore diagnosed. As for treatment, hemostatis was successfully achieved by an improvement in advanced fibrinogenolysis. DIC, associated with a variety of basal disorders and varying conditions, requires immediate corrective action under an appropriate diagnosis.

    We report a case of DIC caused by a central-venous-catheter-related infection after surgery for tongue cancer. In a 61-year-old man with tongue squamous cell carcinoma, a central venous catheter was inserted percutaneously in the subclavian vein using aseptic technique in the operating room to deliver preoperative intra-arterial chemotherapy (CDDP 150mg) with concurrent radiotherapy (20Gy). After chemoradiotherapy, he underwent tumor resection and neck dissection. On the 3rd postoperative day, a high fever above 39 V developed, suggesting sepsis. The central venous catheter was removed on the same day. DIC was diagnosed on blood examination, showing CRP 15.6, platelet count 65000, and FDP 39.2 μg/ml. Heparin and FOY were administered. Fever resolved immediately, and the platelet count and FDP also returned to normal by the 10th postoperative day. A catheter-related infection was diagnosed because culture examinations isolated the same Staphylococcus genus from the catheter tip and arterial blood, as well as 3-day consecutive venous blood samples. Furthermore, susceptibility testing for Staphylococcus genus from the catheter tip, arterial blood, and venous blood samples consistently demonstrated the same sensitivities to antibiotics. Early recognition of central-venous-catheter-related infection and appropriate treatment including prompt removal of the catheter is of great importance in the perioperative management of high-risk patients.

    In recent years, bisphosphonates inhibiting bone resorption have been used to treat multiple myeloma, bone metastases from mammary and prostate carcinomas, and osteoporosis and have been proven to be useful. However, mainly in Europe and the USA, osteonecrosis of the jaw (ONJ) has been reported as an adverse reaction of bisphosphonates, although it was not obvious during clinical trials. More recently, a few cases of ONJ have been reported in Japan, and surveys of bisphosphonate-associated ONJ in the oral and maxillofacial region have begun.
    In this paper, we present two cases of bisphosphonate-associated ONJ. The first case was diagnosed in a 68-year-old woman. It was treated as poor healing of a postextraction wound, and 1 year later, we found out that the diagnosis was ONJ caused by bisphosphonates used to treat osteoporosis on reviewing her medical history. The second case was in a 64-year-old woman who received bisphosphonates for multiple myeloma. Although clinical symptoms now are stable in both cases, ONJ continues to progress radiographically. Therefore, the establishment of effective therapy for ONJ is needed. Our experience highlights the importance of carefully reviewing patients' past history and shows that dentists require knowledge on ONJ to correctly diagnose this condition.
