JOURNAL FREE ACCESSCarcinoma in pleomorphic adenoma (CPA) of salivary gland origin is a relatively uncommon neoplasm. CPA accounts for 3 % to 10% of all tumors arising in the salivary glands.
Recently, we encountered a case of CPA metastasizing from the right parotid gland to the left side of the mandible in a 70-year-old woman.
She had swelling and spontaneous pain of the left side of the mandible. At initial examination, the clinical diagnosis of the parotid gland was pleomorphic adenoma, and that of the mandible was a malignant tumor. Surgical removal of these tumors was performed, and the histopathological diagnosis was CPA in the parotid gland and mandible.
The patient must be followed up for a long time and local recurrence must be controlled.View full abstractDownload PDF (5837K) -

JOURNAL FREE ACCESSA case of peripheral ameloblastoma with histopathologic evidence of clear cell components in a 46-year-old man is reported. The tumor was located in the lower right premolar region, and was excised en bloc from the mesial side of the first premolar to the distal side of the second premolar, with the patient under general anesthesia. On examination 4 years later no sign of recurrence was found.
Histopathologically, the tumor had an ameloblastomatous structure with clear cells consisting of ovoid, clear cytoplasm and pyknotic nuclei. The area containing clear cells show direct transition to, or intermingling of, typical follicular areas, and tumor nests invaded bone, which suggested that the tumor had an aggressive biological character.View full abstractDownload PDF (3330K) -

JOURNAL FREE ACCESSHemangiomas and vascular malformations often occur in the oral facial region. They can be classified as low-flow type or high-flow type, which have very different characteristics and prognoses. Both types must be carefully managed.
We describe a lesion arising in the upper lip and measuring 25×20mm. Pretherapeutic angiography demonstrated low blood flow from the facial arteries through the tumor. Sclerotherapy was therefore performed. We used 10% ethanolamine oleate (EO) as the sclerosing agent, which is used for the endoscopic treatment of esophageal varices. After the injection of 10% EO, the lesion shrank and a good aesthetic outcome was obtained. There were no problematic side effects.
When indicated, sclerotherapy with 10% EO is a simple and safe technique, provided it is performed correctly, sclerotherapy was considered very useful for lesions in which surgical treatment would result in considerable functional and aesthetic disfigurement.View full abstractDownload PDF (2778K) -

JOURNAL FREE ACCESSWe reviewed the records of 168 patients who underwent oral and maxillofacial reconstruction to evaluate the success ratio and the incidence and cause of flap-related complications. A total of 96 pedicled flaps were studied: 58 pectoralis major myocutaneous flaps, 35 deltopectoral flaps, 2 latissimus dorsi myocutaneous flaps, and 1 forehead flap. A total of 80 free flaps were studied: 43 rectus abdominis myocutaneous flaps, 33 forearm flaps, three scapular osteocutaneous flaps, and 1 free latissimus dorsi myocutaneous flap. Among the 96 pedicled flaps, total flap necrosis occurred in 9 (9.4%), partial flap necrosis in 3 (3.1%), and marginal flap necrosis in 11 (11.5%). Among 80 free flaps, total flap necrosis occurred in 1 (1.3%) and marginal flap necrosis in 1 (1.3%). Necrosis of pedicled flaps was mainly attributed to technical errors, i.e. compression and tension of the pedicle. Two of 3 free flaps with venous thrombosis (3.8%) were salvaged by re-exploration.View full abstractDownload PDF (422K) -

JOURNAL FREE ACCESSWe report a case of calcium pyrophosphate dihydrate (CPPD) deposition disease (pseudogout) involving the temporomandibular joint (TMJ). To our knowledge, this condition has been reported in 19 patients in the literature. A 45-year-old woman noted swelling with spontaneous pain in the left preauricular area. There was no history of a familial preposition to TMJ disorders or of metabolic disturbances, trauma, or systemic joint disease. The interincisal distance was limited to 28 mm without pain. Radiological examination revealed different sized radiopaque structures in the posterior and lateral areas of the left TMJ. Extirpation of the mass and diskectomy were performed. The surgically removed material, which measured 18×18×8mm, was a whitish-yellow solid mass. Histological examination showed the crystal deposits to be birefringent under polarized light. Scanning electron microscopy with energy-dispersive X-ray spectroscopy was performed on the histologic sections as well as on commercially available CPPD crystals. The material had a calcium to phosphorus ratio of about 1.1, strongly suggesting a diagnosis of CPPD deposition disease. After more than 7-months of follow-up, there have been no signs or symptoms of recurrence.View full abstractDownload PDF (2965K) -

JOURNAL FREE ACCESSA 30-year-old man was referred to our hospital because of a white lesion of the palate. He had similar lesions involving the uvula, tongue, buccal mucosa, and lips. These lesions were associated with various types of oral candidiasis, such as pseudomembranous, erythematous, hyperplastic, and angular cheilitis. The patient had been febrile for several months, and the fever was associated with the occurrence of the oral lesions. The clinical diagnosis was oral candidiasis with immunodeficiency. A blood test showed that the CD 4-CD 8 cell ratio was less than 0.1, and additional tests revealed that he had AIDS. The oral lesions were resistant to amphotericin B. The patient died of Pneumocytis carinii pneumonia 9 months after presentation.View full abstractDownload PDF (2854K) -

JOURNAL FREE ACCESSCongenital antithrombin III (AT M) deficiency is inherited as an autosomal dominant trait. Patients with this condition have an increased risk of venous thrombosis, developing either spontaneously or after trauma, surgery, or pregnancy.
We performed dental extraction in a 31-year-old man with congenital AT III deficiency who was given only warfarin preoperatively and postoperatively. His AT M activity was 56.2%. During warfarin therapy, the results of the thrombo test and the International Normalized Ratio were 9.7% and 1.88, respectively.
After consultation with physicians, we decided to extract teeth while the patient continued to receive his current regimen of warfarin therapy, because his laboratory data were stable and it was important to avoid venous thrombosis. Dental extraction was performed in 3 blocks to minimize the risk of surgery. Primary hemostasis was completely achieved. Although the patient did not receive AT III concentrate, there was no postoperative hemorrhage or episodes of thrombosis.
Our findings suggest that oral surgeons should carefully consult with physicians when planning dental extraction in patients with AT M deficiency who are receiving anticoagulant therapy.View full abstractDownload PDF (2970K) -

JOURNAL FREE ACCESSThrombocytopenic purpura occasionally occurs in patients with infectious disease.
Mumps developing after thrombocytopenic purpura is very rare, in contrast to measles, rubella, and infectious mononucleosis.
This report describes a case of thrombocytopenic purpura occurring after mumps.
A 6-year-old boy visited our hospital because of severe bleeding in the oral cavity. Although bleeding occurred the day before presentation, it stopped within the same day. On the next day, bleeding recurred. Physical examination confirned bleeding in the oral cavity and some purpura on the back, abdomen and neck. The platelet count was 0.4×104/μl. The bleeding time was prolonged, but the coagulation time was normal. No antiplatelet antibodies were found. The patient had had mumps about 30 days previously, and the mumps antibody titer was 1/128.
The diagnosis was thrombocytopenic purpura occurring after mumps, and steroid therapy was given. Fourteen days later, the platelet count returned to nomal, and the bleeding and purpura resolved.View full abstractDownload PDF (2648K) -

JOURNAL FREE ACCESSWe report a patient in whom a foreign body in the pterygopalatine fossa was removed after 30 years. The patient was a 32-year-old woman. When she was 2 years old, the edge of a scissors entered the left cheek and remained accidentally in the pterygopalatine fossa. There were no complications up to the present.
We removed the cutting edge of the scissors via an intraoral approach with the patient under general anesthesia. There was no remarkable bleeding or liquorrhea. During the operation, we used X-ray-fluoroscopy to confirm the exact position of the foreign body, and this technique was useful.View full abstractDownload PDF (3279K) -

JOURNAL FREE ACCESSWe present a very rare case of an exostosis at the mandibular angle associated with inflammatory symptoms of the oral floor caused by sialolithiasis of the submandibular gland. A 52-year old woman was referred to our clinic in March 1993 because of tenderness at the left mandibular angle. At presentation, clinical examination revealed diffuse swelling at the left side of the oral floor. Radiographically, there was a radiopaque image inside the left mandibular angle. It appeared to be a salivary stone, and it was impossible sialographically to depict the mandibular gland because of an obstacle at the salivary duct. A computed axial tomogram obtained parallel to the mandibular plane revealed a dense bony oval mass contiguous with the lingual cortical bone of the mandible behind the submandibular gland. Magnetic resonance images showed that the submandibular gland was dislocated because of pressure applied by the bony mass. Surgical excision of the mass, measuring 10×8×7mm, was performed with the patient under general anesthesia. The pathological diagnosis was not an osteoma but an exostosis of mandibular bone. Postoperative sialography depicted a normal submandibular gland without inflammation. The inflammatory signs and symptoms around the submandibular gland were apparently caused by pressure applied by the exostosis.View full abstractDownload PDF (5732K) -

JOURNAL FREE ACCESSWe report a rare case of a traumatic parotid cyst arising in the area from the superficial lobe of the parotid gland to the parapharyngeal region. The results of diagnostic assessments by radiographic examination and of biochemical and cytomorphological analyses of aspirated fluid indicated the presence of an extravation cyst with fluid containing inflammatory effusions, cleavaged products of tissue, and saliva. After aspiration of the fluid, the volume of the cyst decreased markedly. Evaluation of this cystic lesion by magnetic resonance imaging showed that the contents of the cyst underwent organization during 3 years of conservative management.View full abstractDownload PDF (5662K) -

JOURNAL FREE ACCESSWe report a case of dermoid cyst in the parotid gland. Intraparotid dermoid cysts are extremely rare, and it is often difficult to differentiate these lesions from other cystic lesions. A 38-year-old woman visited our department because of a swelling in the right parotid region. Physical examination revealed two masses in the parotid gland. These masses were preoperatively diagnosed as dermoid or epidermoid cysts in the parotid gland on sialogramcomputed tomography (CT) and magnetic resonance imaging (MRI). Both cysts were removed surgically. One was located in the superficial lobe, and the other was located in the deep lobe. Histopathologically, the wall of the former cyst was lined by a thin layer of fibrous connective tissue, whereas, the wall of the latter was lined by stratified squamous epithelium with sebaceous glands and hair follicles. Sialogram-CT and MRI were useful for preoperative diagnosis of this case.View full abstractDownload PDF (6036K)
