JOURNAL FREE ACCESSLeiomyosarcoma is a malignant neoplasm of smooth muscle origin. This tumor very rarely arises in the oral region. We report a case of leiomyosarcoma arising in the mandible. A thumb-sized tumor was found in the right ramus of the mandible. Radiographically, the lesion showed a defined area of osteolytic destruction with perforation of the lingual cortex, including the mandibular canal. A diagnosis of leiomyosarcoma was made after initial incisional biopsy of the lesion. A partial mandibulectomy was followed by reconstruction with a dynamic mandibular reconstruction plate and a D-P flap. One year after the surgical procedure, the patient remains free of disease. Immunohistochemical studies confirmed the diagnosis of leiomyosarcoma.View full abstractDownload PDF (2201K) -

JOURNAL FREE ACCESSA 65-year-old man visited our hospital on November 8, 2000 because of pain in the right cheek mucosa. He had diabetes mellitus and hypertension and was a carrier of hepatitis B virus. After excision of the tumor, right conservative neck dissection and microvascular reconstruction with a free rectus abdominis muscle flap, he received ventilatory assistance for 3 days. He was given antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs) for postoperative pneumonia and a wound infection. On 17th postoperative day, the hemoglobin level suddenly decreased from 9.5g/dl to 8.0g/dl over the course of 2 days. Gastrointestinal examination showed no bleeding points. A new episode of massive bleeding occurred on the 21st day. The bleeding point could not be identified by colonoscopicexamination, radioisotope angiography, or angiography of the artery. However, a wide shallow ulcer of the rectum was finally found 2cm from the anal verge on another colonoscopic examination on the 28th day. The AHRU in this patient might have been caused by postoperative stress, a large dose of NSAIDs, underlying disease, or a combination of these factors.View full abstractDownload PDF (1718K) -

JOURNAL FREE ACCESSWe reported a rare case of spindle cell lipoma of the tongue. A 56-year-old man was referred to our department because of a painless swelling on the right tip of the tongue. A clinical examination revealed a mobile, well-demarcated, mass of the tongue that measured 35mm in diameter. A histopathological diagnosis of a solitary fibrous tumor was made on examination of a biopsy specimen. The tumor was removed surgically with the patient under general anesthesia. Histopathological examination of the surgical specimen showed a spindle cell lipoma. There have been no signs of recurrence in the approximately 11 months since the operation.View full abstractDownload PDF (1723K) -

JOURNAL FREE ACCESSWe report an osteoma in the right maxillary sinus that was removed by means of a fiberscopeassisted operation. The patient was a 33-year-old man. His chief complaint was dull pain in the right cheek region. Computed tomography showed a lesion with an ossified rim in the right maxillary sinus. A fiberscopic operation was performed using a 0.8-mm rod-lens fiberscope. Fiberscopic examination of the lesion revealed that the mass was covered by mucosa of the maxillary sinus and that the mass had bony pedicles on the sinus wall. The mass was removed with the patient under local anesthesia. The pathological diagnosis was osteoma. After operation, the pain and swelling were slight. The prognosis remains good 10 months after the operation, with no signs of recurrence. In conclusion, the surgical procedure we used is considered useful since it is minimally invasive.View full abstractDownload PDF (2677K) -

JOURNAL FREE ACCESSA rare case of a large peripheral osteoma in the maxillary molar region is reported. The patient was a 27-year-old Philippine woman who complained chiefly of a painless mass in theoral cavity and an articulatory disturbance caused by the mass. Physical examination disclosed a firm hard mass adhering to the right maxillary molar region. The mass measured about 30×25×20mm. Radiographic examination demonstrated an elliptical radiopaque lesion in the right upper molar region and an impacted third molar under the lesion. A computed tomographic scan showed that the right mandibular ramus was resorbed by the expandingmass. The clinical diagnosis was osteoma. Surgical removal of the mass and the impacted third molar was performed under general anesthesia. The histopathological diagnosis confirmed osteoma spongiosum. Generally, osteoma is not a rare disease in this region, but such a large lesion as that seen in our patient associated with articulatory disturbance and resorption of the mandible is extremely rare. Thirty months after surgery, there have been no signs of recurrence or articulatory disturbance.View full abstractDownload PDF (3034K) -

JOURNAL FREE ACCESSSialodochitis fibrinosa is a rare disease that is characterized by paroxysmal, intermittent swelling of the salivary gland due to obstruction of the duct system by fibrinous plugs.This paper reports a case of sialodochitis fibrinosa affecting both parotid glands. The patient was a 52-year-old woman with recurrent bilateral swelling of the parotid glands. Histopathological examination of fibrinous plugs extruded from the parotid duct revealed numerous eosinophils, and blood examination showed an increased IgE level. The segmental dilatation of the parotid ducts was confirmed on radiography with contrast media. Symptoms wererelieved by administration of antihistamines and irrigation of the parotid glands.View full abstractDownload PDF (1623K) -

JOURNAL FREE ACCESSA rare case of a penetrating injury extending from the mental region to the skull base is reported. A 32-year-old man was referred to our hospital because of a nail stuck in his mouth. There was swelling of the left eyelid and a stab wound in the mental region. He was fully conscious and neurologically intact, but could not speak because of the nail. On skull X-ray films, the nail was seen in the midface, passing obliquely through the left orbital apex in the direction of the anterior cranial fossa. A computed tomographic scan showed that the tip of the nail reached the orbital roof, but there were no signs of brain damage. The nail was extracted via an intraoral approach with the patient under neuroleptic-induced analgesia. There was slight bleeding but no leakage of spinal fluid. The patient concurrently received antitetanus serum, tetanus toxoid, and antibiotics. He was discharged on the 15 day without any complications.View full abstractDownload PDF (3565K) -

JOURNAL FREE ACCESSA case of thrombocytopenia that rapidly developed 6 days after extraction of an impacted third molar is presented. A 28-year-old man with sudden bleeding from the cavity remaining after extraction of a third molar was referred to our department. Initial laboratory data showed a bleeding time of more than 20 min and a platelet count of 2000/μl. There was no history of hemorrhagic disorders. Finally, the patient was admitted to the department ofinternal medicine of our hospital because of thrombocytopenia. Repeated transfusions of concentrated platelets were effective, and the platelet count remained at 76, 000/μl on the 4 th day after admission. The patient was discharged on the following day with no subsequent sign of recurrence. Further laboratory data showed a considerable increase in PAIgG and no abnormal findings in bone marrow. Because the transfusion of concentrated platelets was effective and five kinds of drugs were administered just before the onset of thrombocytopenia, drug-induced thrombocytopenia was suspected. The results of drug lymphocyte stimulation tests suggested that cefaclor was immunologically associated with this case becauseit was only drug that tested positive.View full abstractDownload PDF (1442K)
