目的    探讨胸锁乳突肌肌瓣即刻修复腮腺肿瘤术后面部凹陷畸形和减少术后味觉出汗综合征（Frey综合征）发生的临床效果。方法    选择2006年1月至2009年1月蚌埠医学院第一附属医院口腔科腮腺肿瘤住院手术患者68例,分为试验组48例、对照组20例。试验组患者按常规“S”切口施行腮腺肿瘤加腮腺浅叶或全叶切除术,同期行胸锁乳突肌肌瓣转移修复术;对照组则不行同期肌瓣修复,经随访对比观察6月至3年。结果    对照组局部凹陷畸形发生率为90%（18／20）,Frey综合征发生率为 55%（11／20）;试验组局部凹陷畸形发生率为16.67%（8／48）,Frey综合征发生率为8.33 %（4／48）,两组间差异有统计学意义（P < 0. 01）。结论    胸锁乳突肌肌瓣转移修复术是一种即刻修复腮腺肿瘤术后面部凹陷畸形和降低Frey综合征发生率的较好方法。

釉质发育不全（amelogenesis imperfecta,AI）是一组影响釉质发育的遗传性疾病,由于釉质形成时造釉器的某些功能障碍,导致釉质在厚度、结构和组织上的改变。临床可分为3型：釉质发育不良型（hypoplastic AI,HPAI）,釉质矿化不良型（hypocalcified AI,HCAI）和釉质未成熟型（hypomaturation AI,HMAI）。AI以牙色改变和釉质缺损为主要表现,严重者可伴有颞下颌关节紊乱病（temporomandibular joint disorders,TMD）等。笔者在临床中遇到1例全口乳牙、恒牙严重AI伴TMD病例,现报道如下。

?? Chemokine stromal cell-derived factor-1??SDF-1??has characteristics of cell migration and is expected to be used in the field of oral tissue repair and regeneration. When the damage occurs in the body's tissues and organs??impaired cells secret and express SDF-1 and recruit bone marrow-derived stem cells or progenitor cells to the injured site??so as to promote the repair of damaged tissue by providing the new blood vessels and cells. This paper summarizes the effect of SDF-1 in oral tissue repair and the direction of future researches of the SDF-1.

Intraosseous epithelioid hemangioendothelioma of the mandible: a case report with an immunohistochemical study

Epithelioid hemangioma is the prototype of a group of vascular tumors characterized by epithelioid endothelial cells. Hemangioendothelioma of bone is a rare lesion that constitutes less than 0.5% of primary malignant skeletal tumors. We report and discuss a case of epithelioid hemangioendothelioma arising intraosseously in the anterior portion of the mandible in a 76-year-old woman. The case was treated successfully by wide resection. Radiographically, the tumor mass showed osteolysis and expansion. Histologically, the tumor showed invasive and destructive growth, although it lacked frequent mitotic figures and severe atypia. On immunohistochemical study, tumor cells exhibited characteristics of mesenchymal and endothelial origin, i.e., strong to moderate immune reactivity against vimentin, factor VIII-related antigen (F8RA), Ulex europaeus agglutinin type 1 lectin (UEA-1), and CD 34, but not against keratin, epithelial membrane antigen (EMA) or S-100 protein (S100). The proliferating cell nuclear antigen (PCNA)-positive cell index was 27.5%. These pathological findings suggested a borderline malignant potential for this tumor. Thus, clinically, wide resection with or without dissection of regional lymph nodes is recommended.     

Epithelioid hemangioendothelioma of the oral cavity

OBJECTIVE: To investigate the clinicopathological characteristics and biologic behaviour of epithelioid hemangioendothelioma in the oral cavity. MATERIALS AND METHODS: The clinical features and pathological findings of nine cases with intraoral epithelioid hemangioendothelioma were reviewed, including immunohistochemistry study. RESULTS: This series comprised seven males and two females aged 6-53 years (mean 28 years). The sites of the tumour included the tongue (n = 4), lip (n = 1), the gingiva and alveoli of the maxilla (n = 1), the gingiva and alveoli of the mandible (n = 1), buccal mucosa (n = 1), and the floor of the mouth (n = 1). A painless solitary mass was the most common presentation and was found in eight cases. On pathology, the tumour grew in short strands, cords or nests of polygonal to slightly spindled epithelioid cells in fibro-myxoid stroma, with formation of intracytoplasmic lumina. Tumour cells were immunoreactive to CD34, FVIIIRAg, and vimentin. Focal-positive cytokeration were observed in three cases. Immunoreactivity for S-100 protein, epithelial membrane antigen (EMA) and human herpesvirus (HHV)-8 was negative in all cases. Two cases recurred after surgical excision, but no patient developed local or distant metastasis. CONCLUSIONS: Wide local excision with long-term follow-up seems to be the treatment of choice for intraoral epithelioid hemangioendothelioma because of their unpredictable biological behaviour and recurrence potential.

Spindle-cell hemangioendothelioma of the oral cavity. A case report

We describe a vascular tumor classified as SCH by histological criteria that was found in the mandibular-buccal fold of a 12-year-old girl. Microscopically, the lesion consisted of thin-walled cavernous spaces containing thrombi and phleboliths, and cellular areas composed of spindle-shaped, epithelioid and vacuolated cells. Immunohistochemically, the endothelial vascular lining was highly reactive with HAM56 antibody, while variable reactivity was observed for factor VIII-associated antigen. All cell types were positive for vimentin and anti-PCNA stained less than 3% of the tumor cells. This is the first report of SCH in the oral cavity.
