青少年结外鼻型NK/T细胞淋巴瘤1例并文献回顾

<正>结外鼻型NK/T细胞淋巴瘤(extranodal nasal NK/T cell lymphoma,NKTCL)是一种罕见的、极具侵略性的恶性淋巴瘤,被认为与EB病毒感染关系密切。首发于硬腭的NKTCL,与许多疾病具有相似的临床表现、病史特点和影像学表现,易引起混淆并导致误诊。结合临床、组织病理学、免疫表型检测和EBER原位杂交技术有助于正确的诊断,必要时需要进行二次活检甚至多次活检,重复活检后的免疫组化和原位杂交分析是正确诊断的关键。

Marfan syndrome: a review of the literature and case report

Marfan syndrome (MFS) is a connective tissue disorder of variable inheritance that affects multiple organ systems. Cardiovascular, ocular, and skeletal abnormalities are cardinal features of the syndrome. Orofacially, MFS patients typically exhibit skeletal class II malocclusion, dolichofacial growth pattern, mandibular retrognathia, malar hypoplasia, high arched palate, dental crowding, and root anomalies. The purpose of this paper is to provide a review of the literature, as well as describe an 11‐year‐old female with MFS diagnosed at the age of 10.5 years. This report emphasizes the orofacial findings in MFS and highlights particularities of dental treatment when social deficits and intellectual disabilities are also implicated.

Oral hairy leukoplakia: observations in 95 cases and review of the literature

Oral hairy leukoplakia (HL) was observed in 25.4% of 373 HIV-seropositive patients (n = 95). 87 were men of an average age of 37.1 yr, 8 were women (30.3 yr). 71.6% of the patients were male homosexuals. At initial diagnosis of HL the majority of cases was classified as CDC IVc1 (45.3%) and CDC II (22.1%). Average CD4/CD8 ratio (n = 19) was 0.24 with a range of 0.04-1.0. Thirty biopsies of HL revealed some of the histologic features thought to be characteristic. In only 20 of 30 biopsies EB-virus-specific-capsid antigen was detected. The problems of clinical and histological diagnosis of HL are discussed. Further strict criteria are necessary in order to define HL more distinctly.     

Phantom bite: a case report and literature review

Objective:

Phantom bite is a rare and challenging condition that dentists may encounter in their daily clinical practice. Patients with phantom bite typically present with many failed repeated occlusal treatments, such as full-mouth prosthetic reconstructions and orthodontic treatments, to overcome their distressing symptoms.

Method and result:

A 55-year-old female with no history of medical problems presented with bite discomfort. She complained of discomfort from a “bite” and pressure-like feeling in her right upper three maxillary posterior teeth. Examination revealed no temporomandibular disorder (TMD) abnormalities. A thorough evaluation of her oral structures revealed no dental, periodontal, or mucosal pathologies.

Conclusion:

Owing to the great potential of conditions for financial loss and litigation problems, dentists, particularly those who perform bite-changing procedures, should be aware of this condition. This case is presented to highlight many of the clinical characteristics of phantom bite.     

Oral myiasis: a case report and literature review

Myiasis is the infestation of tissues and organs of animals and humans by certain Dipteran fly larvae. This phenomenon is well documented in the skin, especially among animals and people in tropical and subtropical areas. Oral myiasis is a rare condition and can be caused by several species of Dipteran fly larvae and may be secondary to serious medical conditions. Upon removal of the larvae, the tissues seem to recover with no subsequent complications and with no need for further treatment. Here we describe a case of oral myiasis within the gingiva of a healthy young man caused by the larvae of Wohlfahrtia magnifica (Family Sarcophagidae), in which infection may have been due to ingestion of infested flesh. Reviewing the literature revealed that most cases of oral myiasis tend to be multiple and to occur in anterior segments of the jaws rather than in posterior segments as in the case we describe here.     

Hereditary angioedema: a case report and literature review

Hereditary angioedema is an autosomal dominant condition with a typical presentation of diffuse edematous, painless, and nonpitting swelling of the soft tissues. The disease manifests itself primarily in the extremities, face, airway, and abdominal viscera. Proper diagnosis and treatment are essential as this condition has the capacity of becoming life-threatening due to potential airway embarrassment. This case report demonstrates the complexity of diagnosing and treating hereditary angioedema. Hereditary angioedema often is overlooked on a differential diagnosis of patients suffering from diffuse swelling and/or abdominal discomfort. Nonetheless, the diagnosis of hereditary angioedema should be included when assessing patients who display the proper symptomology and familial history of the condition.     

Endodontic-related paresthesia: a case report and literature review

Introduction

Endodontic-related paresthesia is a potential complication despite the development of endodontic materials and techniques. We describe a case of periapical lesion-induced paresthesia that was successfully treated endodontically. The literature review of endodontic-related paresthesia is also presented.

Methods

The patient sought treatment from a general practitioner for lower lip paresthesia as the only symptom. Paresthesia was present on the left side of the lower lip extending from the mandibular midline to the second premolar both extraorally and intraorally in the area of mental nerve stem. Apical lesion of an endodontically treated second premolar with short obturation was observed radiographically. Retreatment was unsuccessful at reaching the apex; instead, swelling, pain, and extension of numbness on the region resulted, and the patient was referred to an endodontist.

Results

The root canal chemomechanical debridement was completed, and calcium hydroxide was placed for the follow-up. Two months later the symptoms had significantly improved, the radiograph indicated partial healing, and the tooth was obturated. The healing progressed so that the symptoms completely resolved within a year after the treatment.

Conclusions

Periapical pathosis might cause paresthesia with a good potential for healing after appropriate endodontic treatment. Complications might be prevented by careful preoperative examination, good quality radiographs, and good instrumentation, irrigation, and obturation techniques. However, according to the literature paresthesia might still occur. In case of treatment-related paresthesia in which apical extrusion of endodontic materials is observed, the need for surgical debridement (especially in cases of extrusion of obturation materials) should be considered within 48 hours.     

Osteoplastic ameloblastoma: a case report and literature review

Ameloblastoma with bone formation is rare. We report a case of a 55-year-old woman with ameloblastoma accompanied by prominent osteoplasia. Histopathological examination exhibited an abundant stromal component between tumor nests. Therefore, she was diagnosed as the desmoplastic variant, except for the numerous bone trabeculae. The distinction between new bone formation and invasion of the bone marrow poses a problem. A thin rim of fibrous bone that can be accentuated by Masson-trichrome staining suggests the former.
