Giant Osteoma of Mandible Causing Dyspnea: A Rare Case Presentation and Review of the Literature

Osteomas are benign slow growing tumors of bone. Tumors are usually asymptomatic until they attain remarkable size and cause asymmetry or dysfunction. In view of few reported cases of giant osteoma of mandible, this article presents a case of giant osteoma of left mandible in a 53-year old male causing dyspnea due to compression of air way space.     

Benign Fibrous Histiocytoma: A Rare Case Report and Literature Review

Fibrous histiocytoma is a benign soft tissue tumour that may present as a fibrous mass anywhere in the human body. The involvement of the oral cavity is extremely rare and very few cases have been reported in literature till date. We here report a case of benign fibrous histiocytoma localized in the oral cavity. The clinical and histological features of the lesion are discussed precisely in the light of a literature review of this pathology in oral cavity.

下颌骨恶性外周神经鞘膜瘤的临床及病理特点——1例报告及文献复习

目的探讨下颌骨恶性外周神经鞘膜瘤的临床及病理特点。方法对1例下颌骨恶性外周神经鞘膜瘤患者的临床资料进行回顾性分析,结合文献复习,探讨其临床特征、组织病理学与影像学特点、治疗和预后。结果该例患者为中年男性,肿物位于左下颌骨区,大小约5cm×6cm,左下唇麻木进行性加重。病理学为肉瘤表现。影像学特点为左下牙槽神经管局部扩大,周围骨质密度较健侧低。行左下颌骨切除、左舌骨上淋巴清扫加肋骨钛板重建术,术后患者接受辅助性放疗45d,共30次,总量60Gy,放疗过程顺利。术后半年肺部转移。结论下颌骨恶性外周神经鞘膜瘤为恶性病变,临床少见,确诊依据病理和免疫组化,治疗以手术为主,预后较差。     

Tongue Spindle Cell Rhabdomyosarcoma: A Rare Case Report and Literature Review

Rhabdomyosarcoma (RMS) is a malignant soft tissue neoplasm with its origin in the skeletal muscle and is extremely rare in adults. By the World Health Organization (WHO), a new variant of RMS has been classified, i.e. the spindle cell (Sc) and sclerosing (S) RMS. While the Sc-RMS shows intersecting fascicles of nonpleomorphic spindle cells, the S-RMS is characterized by a marked hyalinization in a pseudovascular growth pattern associated with round-to-spindled tumour cells. According to the analysed data, the Sc/S-RMS variant has a worse outcome than other variants. The new classification of the Sc/S-RMS variant is valuable to the clinical practice. There are not many oral Sc/S-RMS cases reported. The aim of this paper is to demonstrate that an early diagnosis, an adequate treatment and a multidisciplinary approach have a positive effect on the prognosis of the patient. In this study, we analyse a new case of Sc-RMS variant in a young adult with an early diagnosis and a favourable outcome as a result of an appropriated multidisciplinary treatment: early surgery, radiotherapy and chemotherapy treatment.     

A Case Report of Solitary,Intraosseous, Adult-Onset Myofibroma of the Mandible

Myofibroma is a benign proliferation of myofibroblasts in the connective tissue. Solitary intraosseous myofibromas are a rare finding especially in an adult. Myofibroma is a benign lesion and its treatment is similar to any other benign lesion.
