1/21. Alveolar rhabdomyosarcoma metastatic to the breast: long-term survivor.

    The case history is described of an adolescent girl with alveolar rhabdomyosarcoma of the maxillary sinus, who was treated with radical radiotherapy and adjuvant chemotherapy. She relapsed in the breast and, after incomplete excision, received radical radiotherapy resulting in long-term survival with breast conservation. The characteristics of patients with metastatic rhabdomyosarcoma with breast involvement are discussed. In adolescent girls, the breast is postulated to be a preferential metastatic site.

2/21. osteosarcoma of the jaw. The Chaim Sheba Medical Center experience.

    OBJECTIVE: The purpose of this article is to present 14 cases of osteosarcoma of the jaw treated at our medical center from 1989 to 1998. These cases are discussed in the light of a comprehensive review of 774 cases reported in the English literature over the past 3 decades. Differences between osteosarcoma of the jaws and osteosarcoma of the long bones are examined. SUBJECTS AND methods: The patients ranged in age from 8 to 78 years, the mean age being 33 years. Each patient had a histopathologically established diagnosis of osteosarcoma of the jaw. Records were reviewed for epidemiologic data, treatment modalities, and survival. RESULTS: Of the 14 patients, 6 (42%) had tumors in the mandible and 8 (58%) had tumors in the maxilla. Of the mandibular tumors, 5 occurred in the body of the mandible; all maxillary tumors originated in the alveolar ridge and involved the maxillary sinus. The chief complaint was an intraoral or extraoral painless swelling. Histopathologic types included chondroblastic, osteoblastic, fibroblastic, and malignant fibrous histiocytoma-like. Pathologic grade was determined to be high (3 or 4) in 13 cases and low (1) in only 1 mandibular case. All patients underwent surgical resection and immediate reconstruction. Adjuvant therapy included postoperative radiation (5 patients), postoperative chemotherapy (2 patients), and preoperative chemotherapy and postoperative radiation (1 patient). CONCLUSIONS: The results of the present study support the literature indicating that osteosarcoma of the jaw differs from osteosarcoma of the long bones in its biological behavior even though they have the same histologic appearance. Because of differences in tumor characteristics, the introduction of chemotherapy did not dramatically alter the prognosis of osteosarcoma of the jaw. early diagnosis and radical surgery are the keys to high survival rates.

3/21. Radiographic evaluation of malignant fibrous histiocytoma affecting maxillary alveolar bone: a report of 2 cases.

    OBJECTIVE: The purpose of this study was to evaluate the radiographic findings of malignant fibrous histiocytoma (MFH) and to discuss the contribution of these findings to a differentiation of MFH from other malignant tumors of the head and neck. STUDY DESIGN: Two cases of MFH of the maxillary sinus affecting the alveolar bone were evaluated radiographically and scintigraphically. RESULTS: We reported the following findings, which have only seldom been described: the presence of fairly well-demarcated bone destruction in the intraoral radiograph; the relatively smooth surface, uniform density, or no necrotic area of the tumor; in computed tomograph images showing the clear separation of the tumor from surrounding soft tissues; bone scintigraphs reflecting the periosteal reaction to tumor invasion; and lymphoscintigraphy of the metastatic lymph nodes. CONCLUSION: We evaluated the radiographic findings from 2 cases of MFH and describe findings that may aid in the differentiation of MFH. These radiographic features may help dentists differentiate MFH from other malignant tumors in the head and neck, although MFH is a rare disease and there are no radiographic findings that would indicate a specific diagnosis of MFH.

4/21. Osteogenic sarcoma after orbital radiation rhabdomyosarcoma.

    PURPOSE: We describe the occurrence of maxillary and orbital osteogenic sarcoma in a child after treatment of contralateral orbital rhabdomyosarcoma with external beam radiation and chemotherapy. DESIGN: Interventional case report. INTERVENTION: Treatment of a maxillary and orbital rhabdomyosarcoma with surgical resection, systemic chemotherapy, and local radiation. MAIN OUTCOME MEASURES: Occurrence and histology of secondary malignancy after orbital radiation. RESULTS: An eleven year-old male presented for evaluation of left facial swelling, occurring ten years after successful treatment of a right orbital embryonal rhabdomyosarcoma with chemotherapy and 5040 cGY of external beam radiation. Computerized tomography demonstrated a mass involving the left maxillary sinus and orbital floor. biopsy demonstrated osteogenic sarcoma. Despite attempted total excision with radical maxillectomy, resection margins were found to have microscopic extension of the tumor. Postoperatively he was treated with systemic chemotherapy and local radiation. Eight months postoperatively he remains alive despite local progression. CONCLUSIONS: Osteogenic sarcoma can occur as a secondary malignancy years after the successful treatment of orbital rhabdomyosarcoma with external beam radiation and chemotherapy. After orbital radiation, subjects should undergo routine lifelong examinations.

5/21. Herniation of an antral polyp through an oroantral fistula.

    This paper reports a case of herniation of an antral polyp through an oroantral fistula, appearing as a polypoid lesion of the alveolar ridge. The patient was a 24-year-old female, and her upper molar had been extracted two months previously. The lesion was asymptomatic, and was a soft tissue mass, red in color and nontender to palpation, involving the alveolar ridge in the maxillary molar area. review of the literature yielded only a few other such cases.

6/21. osteosarcoma of the jaws in children.

    Two cases of osteosarcoma of the jaws in children are reported. One patient was a 13-year-old girl whose first symptoms included nasal and maxillary sinus congestion, followed by epistaxis. She was found to have chondroblastic osteosarcoma extending through the left maxillary alveolar process and sinus. Following surgery and chemotherapy, the patient has been free of disease for 7 years. The second patient, an 8-year-old boy, was diagnosed with juxtacortical (parosteal) osteosarcoma of the mandible, which is a less aggressive variant of the neoplasm. It is believed that this is the youngest patient reported to date with juxtacortical osteosarcoma of the jaws. He was treated by block resection of the right side of the mandible and is free of disease 3(1/2) years later.

7/21. Complex odontoma of unusual size involving the maxillary sinus: report of a case and review of CT and histopathologic features.

    An unusually large complex odontoma of the maxilla, occupying the entire maxillary sinus with expansion into the floor of the orbit and left nasal fossa, is reported. Although occurrences of complex odontomas are not considered rare, odontomas attaining extremely large sizes, especially involving the entire maxillary sinus with extension to the orbital floor and nasal fossae, are indeed, rare. In this article, the literature is reviewed to identify the common clinical, radiographic, and histologic characteristics of such lesions, and the outcome of treatment is discussed. Complex odontomas occasionally have significant growth potential, especially in the first two decades of life. Early recognition and consideration for surgical excision are key to successful management of this common odontogenic lesion. When odontomas extend beyond the alveolar process into the fascial planes, nasal fossae, paranasal sinuses, and orbits, computed tomography can readily demonstrate the extent and boundaries of the lesion.

8/21. Sinonasal myxoma: a pediatric case.

    The authors report a case of a rare facial myxoma arising from the maxillary sinus in a 20-month-old child. The diagnosis was confirmed by a biopsy, and the patient underwent a partial maxillectomy to achieve a total resection of the mass due to the locally aggressive nature of the lesion. Myxomas should be differentiated from malignant sarcomas, in particular embryonal rhabdomyosarcoma, which can arise from the same location and require multimodality therapy consisting of surgery, irradiation, and chemotherapy.

9/21. rehabilitation of a bilateral maxillectomy patient with a free fibula osteocutaneous flap.

    rehabilitation of patients who have undergone bilateral maxillectomy is difficult because of extensive loss of bone and soft tissue. In this clinical report, prosthodontic rehabilitation of oral function in a bilateral maxillecitomy patient combined with a new fibular osteocutaneous flap, which was designed to have two oronasal slits for the retention of an obturator prosthesis, was described. A 58-year-old man with a maxillary alveolar carcinoma underwent bilateral maxillectomy. The defect was reconstructed using a vascularized fibular bone wrapped circumferentially with a peroneal flap, which was fixed with miniplates between the right malar prominence and cut edge of the left zygoma remaining two slits anterior and posterior to the graft. Two and half weeks after the surgery, a delayed surgical obturator was delivered and an obturator prosthesis was delivered 6 weeks after the surgery. This obturator prosthesis could be extended into the slits to engage the tissue undercuts, and was stable during use. mastication, deglutition, articulation and the mid-facial profile of the patient were rehabilitated. After installation of the obturator prosthesis, relining of the prosthesis base was carried out alongside the healing process of the graft, and adjustment of occlusions and high-pressure spots was carried out. No clinical disorders were observed either in the grafted tissue or the obturator prosthesis with a 3-year prognosis. Newly designing a fibular osteocutaneous flap combined with tissue-borne obturator prosthesis is one successful approach to the restoration of oral function, and increases the patient's quality of life after bilateral maxillectomy.

10/21. Malignant fibrous histiocytoma of the maxillary sinus. A case report.

    We report a case of malignant fibrous histiocytoma of the left maxillary sinus in a 30 year-old man. The major problem encountered was the histological diagnosis of the first biopsy, which showed a non specific fasciculated, myxoid, alveolar pattern suggestive of a mesenchymal malignancy, thus preventing the correct diagnosis that became possible only when the surgical specimen was available.
