Huge osteoma of the mandible: report of case.

A review of the literature on osteoma of the jaws as well as its relationship to Gardner syndrome was presented. A case report of a compact or ivory osteoma that had been slowly enlarging for a minimum of eight years was described. The one-year postoperative examination has shown no discernible resumption of growth.     

A giant osteoma of the mandible: case report.

A 53-year-old patient with a giant osteoma of the right mandible is presented. The clinicopathological features of osteoma of the mandible are discussed and Gardner's syndrome was excluded.     

Chondrosarcoma of the mandible: case report and literature review

Chondrosarcoma is a malignant cartilaginous tumor that rarely occurs in the maxillofacial bones. A 44-year-old woman complained about swelling and mild pain during mastication in the right parasymphysis region. Clinical and radiographic examinations revealed characteristics of osteosarcoma. A microscopic examination revealed an abundant proliferation of malignant neoplastic cartilage cells of varying sizes arranged as immature tissue and the absence of an osteoid matrix. This article presents a case of chondrosarcoma of the jaw and discusses the differences between osteosarcoma and chondrosarcoma.     

Gigantic osteoma of the mandible: report of a case.

A case of a very large solitary osteoma of the right posterior mandible in a 22-year-old man is presented. The tumor was asymptomatic despite its location and large size. It was removed via an extraoral Risdon approach without complication. The importance of differentiating a large solitary osteoma from a parosteal osteogenic sarcoma is emphasized. Any patient presenting with a solitary osteoma also should be evaluated for Gardner's syndrome.     

Peripheral osteoma of mandible arising from anterior lingual alveolar plate--a case report

Peripheral osteomas of the mandible are uncommon bony tumours. Of those that have been described, the location is normally posterior to the premolars on the lingual surface of the mandible or in the condylar area. This article presents a case of an atypical presentation of an osteoma arising from the anterior lingual alveolar cortical plate of the mandible.     

Peripheral ameloblastoma: report of case and review of the literature.

A case of an extraosseous ameloblastoma occurring in a 33-year-old woman has been described. Of the 11 cases documented in the literature, only nine fulfill the histologic and clinical criteria for a true peripheral ameloblastoma. In contrast to the intraosseous ameloblastoma, the diagnosis of extramedullary or peripheral ameloblastoma implies a less aggressive neoplasm that can be treated by a more conservative surgical approach.     

Peripheral primitive neuroectodermal tumor associated with the anterior mandible: a case report and review of the literature

Neuroectodermal tumors may arise in many places throughout the body including the diverse tissues of the head and neck. The primitive neuroectodermal tumor is a predominately neural, nonepithelial neoplasm similar to Ewing sarcoma. This article describes an 18-year-old female patient with a highly malignant peripheral primitive neuroectodermal tumor located in the soft tissue anterior to the mandibular symphysis. The clinical and radiographic presentation as well as the histopathology and immunohistochemistry of this rare entity is discussed. A review of the literature with respect to this tumor, as well as the current management of this tumor, is presented.     

Peripheral ameloblastoma. A case report and review of the literature.

Peripheral ameloblastoma is a benign odontogenic tumor with the same histological characteristics as the centrally located ameloblastoma, but appearing in the gingiva and mucosa of the tooth-bearing area of the jaws. A review is presented of 53 cases: 45 being reported as peripheral ameloblastoma and 8 as basal cell carcinoma of the gingiva, including the case presented. Based on the review it is recommended to treat this lesion by local excision including a small margin of healthy tissue. Local recurrence is unlikely, unless incomplete removal is performed.     

A trifungal infection of the mandible: case report and literature review

Orofacial fungal infections are occasionally seen in the immunocompromised patient. In this case, a patient with a relapse of an acute lymphoblastic leukemia (ALL) developed a fatal mandibular infection. This may be the first reported case of a trifungal infection with zygomycosis, aspergillosis, and candidiasis in the oral cavity and the fifth mandibular zygomycosis case. Epidemiology, diagnosis, treatment and prognosis of zygomycosis infection are reviewed, along with the 4 mandibular zygomycosis cases found in the English literature.     

Peripheral ameloblastoma: a case report and review of the literature

Peripheral ameloblastoma is a rare, benign odontogenic tumor that histologically resembles an intraosseous ameloblastoma but develops in the soft tissues of the gingiva and mucosa and exhibits an innocuous clinical behavior. We report a case of a recurrent peripheral ameloblastoma in a 61-year-old man that presented as a painless swelling on the maxillary anterior labial attached gingiva. Clinical and histopathologic features of this lesion are discussed. The peripheral ameloblastoma should be included in the differential diagnosis of a gingival lesion clinically resembling any of the myriads of entities seen on the gingiva including a pyogenic granuloma, peripheral giant cell granuloma, or parulis/gumboil. We believe this case highlights the need for submitting excised tissue for microscopic examination.     

Angiosarcoma of the mandible: a case report and review of the literature

Angiosarcoma is a rare malignancy that is characterized by endothelial cell differentiation. In the head and neck area, most of these lesions arise in the scalps of elderly individuals. Less commonly, angiosarcomas can be found within bone. The purpose of this report is to describe an example of angiosarcoma involving the floor of the mouth and right body of the mandible. The histopathologic and immunopathologic features of these lesions are also reviewed.     

Solitary neurofibroma of the mandible: case report and review of the literature

A case is presented of a neurofibroma of the mandible without recurrence 6 years after surgery. Search for neurofibromatosis was negative. Eradication of the tumor was explained by the extent of the operation that was performed.     

下颌骨成釉细胞癌1例报告及文献复习

成釉细胞癌是一种罕见的恶性骨内肿瘤,目前文献报告例数较少,因而该疾病的流行病学、治疗方式以及预后仍不清楚。作者报告成釉细胞癌1例,采用病灶及病灶周围2cm颌骨、软组织扩大切除方式,病理检查证实为成釉细胞癌,术后未行放疗或化疗。目前患者正随访中,无复发及远处转移迹象。     

下颌骨滑膜肉瘤诊治初探及文献回顾

目的分析总结下颌骨滑膜肉瘤的临床及病理特点。方法分析1例左下颌骨滑膜肉瘤患者的临床资料,并检索和回顾分析相关中英文文献。结果收集文献6篇（中文1篇,英文5篇）,其中个案报道4篇,病例总结2篇。结论下颌骨滑膜肉瘤是一种较为罕见的颌骨肿瘤,男性多于女性,缺乏特异性的临床表现,确诊需依据病理和免疫组化。该肿瘤恶性程度较高,复发率高,预后较差,应扩大切除肿瘤及周围组织,并适当辅以放、化疗。
