1/135. Central neurilemmoma of the jaws. review of literature and case report.

    Neurilemmomas presenting as primary central bone tumors are extremely rare. Only 21 cases have been reported to have arisen in the jaws; all except for one have occurred in the mandible. The majority of these have been associated with the inferior dental nerve. A case of a central neurilemmoma arising in the anterior mandible is reported. Its probable origin is from one of the alveolar branches of the incisive nerve--an unusual site in the mandible. The radiographic features include expansion of cortical bone, resorption of roots of teeth, the presence of lace-like bony septa and a spotty calcification within the tumor. The treatment and the prognosis are briefly discussed.

2/135. leiomyosarcoma presenting as a mandibular gingival swelling: a case report.

    We report a case of primary low-grade leiomyosarcoma of the mandible in an otherwise healthy young woman. The neoplasm presented as a painful, pericoronal gingival swelling that mimicked an acute periodontal infection. It was managed accordingly, with curettage, debridement, and antibiotics. When the lesion failed to respond to this treatment approach, a biopsy was performed. microscopy revealed a malignant mesenchymal neoplasm which, on immunohistochemistry analysis, demonstrated reactivity for smooth muscle actin (SMA) and vimentin. This established the diagnosis of leiomyosarcoma; subsequently, an en bloc resection of mandibular bone and overlying soft tissue was performed. Close follow-up for over 10 years has revealed no evidence of recurrent or metastatic disease. Since the patient was taking oral contraceptives prior to the onset of the lesion, a possible link between estrogen and smooth muscle tumors is considered.

3/135. The experience of a senior dental student in diagnosing pathology.

    Dental school affords the opportunity to use various dental sciences, that is, radiology, pathology, histology, oral and maxillofacial surgery, in determining normal and pathological conditions. The case presented here describes the diagnosis, treatment and management of a rare intraosseous lesion, calcifying epithelial odontogenic tumor (CEOT), from the perspective of a senior dental student.

4/135. Malignant spindle cell tumor arising in the mandible of a patient with florid osseous dysplasia.

    Florid osseous dysplasia is a non-neoplastic condition of the alveolar processes of the jaws characterized by the replacement of multiple foci of bone by fibrous connective tissue, accompanied by gradual deposition of cementum, bone, or both. The lesions are not associated with inflammatory diseases of the dental pulp or periodontal tissues. In fully developed florid osseous dysplasia, there are multiple lobulated masses in the alveolar bone bilaterally in the mandible and sometimes in the maxilla. This is the first report of a malignancy originating within the jaws of a patient with florid osseous dysplasia. A spindle cell malignancy was diagnosed in the mandible of a 54-year-old black woman whose jaw was affected by florid osseous dysplasia bilaterally. Despite extensive surgery and radiotherapy, the patient died 20 months after diagnosis of the malignancy.

5/135. Primary intraosseous carcinoma of the mandible with probable origin from reduced enamel epithelium.

    This report describes a case of primary intraosseous carcinoma (PIOC) arising de novo in the mandible. The patient was a 74-year-old woman and an early PIOC was found incidentally during histopathological examination of the pericoronal tissue obtained at extraction of a deeply impacted third molar. The curetted soft tissues consisted of a microinvasive, keratinizing squamous cell carcinoma with scattered foci of carcinoma cells showing calcification; stromal osseous metaplasia was also observed. After additional treatment, the patient has remained free of disease for 2 years. Since the tumor was completely enclosed in the bone, the only identifiable source of the present PIOC is the reduced enamel epithelium. Despite its rarity, this case emphasizes the importance of careful histologic examination of all apparently innocuous dental follicles that are removed surgically.

6/135. jaw and pulpal metastasis of an adrenal neuroblastoma.

    Hematogenous spread of malignant tumors to the dental pulp is very rare. A case of adrenal neuroblastoma in a 71/2-year-old boy which metastasized to the mandible and dental pulp is described. Tumor cells were found within the pulpal blood vessels of a deciduous molar tooth.

7/135. Parosteal osteogenic sarcoma of the mandible, Existence masked by diffuse periodontal inflammation.

    A 38-year-old man was in a state of poor oral hygiene, with multiple broken carious teeth and diffuse inflammatory hyperplasia of the gingival tissues. A mandibular, alveolar soft tissue mass in the premolar-molar region was noted on the right side, in continuity with the gingival hyperplasia. biopsy of the lesion ruled out a diagnosis of squamous cell carcinoma. The patient underwent extraction of his teeth, and all hyperplastic tissues including the tumefaction were excised. Five months later, the patient had a recurrent mass in the same location that was removed via hemimandibulectomy. The mass was diagnosed as a parosteal osteogenic sarcoma.

8/135. Peripheral fibroma with calcification--a case report.

    A female patient aged 10 years reported with an intra oral swelling on the labial aspect of 32 & 33, appearing to originate from the marginal gingiva & interdental papilla. The swelling was pedunculated, mobile, non-tender, firm in consistency with an irregular surface. The colour of the gingiva was normal with slight ulceration. The swelling was excised & diagnosed histopathologically as peripheral cementifying/ossifying fibroma.

9/135. Dental blood supply in the segmentally resected mandible.

    There are approximately 30,000 new cases of oral and pharyngeal carcinoma treated in the united states each year. A large number of these patients go on to receive segmental resection of the mandible, and have natural teeth remaining on the surgical side. To the best of our knowledge, there has not been a thorough discussion of the blood supply to these remaining teeth. Radiographic evidence of periapical pathology in these teeth is unusual, despite the compromised vascular supply. The purpose of this article is to report a case and review the literature on blood supply to teeth after segmental mandibulectomy. Microscopic examination was conducted on the pulpal tissue of a premolar retained on the side of, and anterior to, a segmental mandibular resection. Although abnormal, the pulp tissue showed evidence of a vascular supply 4 yr after mandibular surgery. A literature review was performed, and a discussion is given to explain the continued vascularity of the dentition through collateral and retrograde circulation. Despite the compromised dental circulation on the surgical side, unless radiographic evidence of periapical pathology occurs, endodontic therapy or extraction is not necessary. Due to the compromised nature of the circulation however, these teeth may be more susceptible to caries or restorative dental procedures that may lead to pulpal necrosis.

10/135. Primary intraosseous carcinoma of the mandible--a case report and review of the literature.

    BACKGROUND: Squamous cell carcinoma arising within bone is a rare lesion and is only seen essentially in the jaw bones. methods: A case of primary intraosseous carcinoma arising in the mandible is reported in a 60-year-old female patient. Twenty-eight cases of primary intraosseous carcinoma published in the literature, till date, are reviewed. RESULTS: The mean age of the patients at the time of diagnosis was 53 years and the male: female ratio was 2.2:1. The posterior mandible was the predominant site. Fourteen of 28 patients presented with routine dental disorders, while eight patients complained of swelling, four of severe pain and three had sensory disturbances. The incidence of lymphadenopathy was 10 (34.481%) out of the 29 cases reviewed here. Wide surgical excision is accepted as the treatment of choice. CONCLUSION: The most common presenting symptom of these tumours is swelling and persistent pain in the jaw. Hence, in making a diagnosis one is likely to consider benign dental conditions. The importance of considering intraosseous carcinoma as a possibility in all cases of persistent pain and swelling in the jaw is emphasized so that suitable treatment can be instituted early.
