S-100蛋白、CD1a、CD83及Ki-67在口腔朗格汉斯细胞组织细胞增生症中的表达及意义

目的对口腔朗格汉斯细胞组织细胞增生症（LCH）病例进行临床病理回顾性研究及多种免疫表型检测,观察该类疾病的临床病理特征,并对其诊断、鉴别诊断等进行探讨。方法选择原病理诊断为LCH的29例患者为研究对象,分析其临床病理特点;采用链亲和素-生物素-过氧化物酶（SP）法和Elivison二步法检测S-100蛋白、CD1a、CD83及Ki-67在LCH中的表达情况,观察其免疫组织化学结果并进行统计学分析。结果29例LCH中有5例S-100蛋白、CD1a检测为阴性,排除LCH诊断。在24例LCH中,男性15例,女性9例;患者中位年龄为7.50岁;14例发生于下颌骨,5例发生于上颌骨,5例发生于上下颌骨;按照Bartnick分类,Ⅰ类9例,Ⅱ类13例,Ⅲ类2例;S-100蛋白、CD1a均为阳性表达;颌面部单发骨病损与侵及软组织的颌面部病损相比,Ki-67阳性率较低,而CD83阳性率较高。结论S-100蛋白、CD1a对于LCH的诊断具有重要意义。颌面部单发的骨LCH可能具有较低的增殖活性,并处于较高的成熟状态;侵及软组织的颌面部LCH可能具有较高的增殖活性,并处于较低的成熟状态。

Recurrent Langerhans cell histiocytosis of the mandible

We report a case of Langerhans cell histiocytosis with a restricted presentation (eosinophilic granuloma of the mandible) complicated by multiple reactivations.     

Langerhans cell histiocytosis presenting as bilateral eosinophilic granulomata in the molar region of the mandible A case report

Abstract. Eosinophilic granuloma represents one of a triad of lesions encompassing a disease under the generic name, histiocytosis X or Langerhans cell histiocytosis. Localised eosinophilic granuloma, muitifocal eosinophilic granuloma, Hand-Schüller-Christian disease, and the most malignant form of histiocytosis, Letterer-Siwe disease, can all present as destructive bony lesions of the jaws. The present case was a 30-year-old man who presented with almost total destruction of the periodontal support to the left and right mandibular, 1st and 2nd molars. Whereas the radiographic features were typical of eosinophilic granuloma, the clinical appearance and mirror image presentation were unusual.     

Incidental Langerhans cell histiocytosis of the parotid gland resembling marginal zone B-cell lymphoma: a case report

Langerhans cell histiocytosis (LCH) manifesting as a parotid gland mass is an extremely rare clinical presentation. We report a case of LCH involving the bilateral parotid glands in an 81-year-old Japanese female. Pathologically, the lesion was characterized by numerous lymphoid follicles, dense lymphoplasmacytoid infiltrate and cystic dilatation of the parotid gland duct in addition to nodular and diffuse proliferation of LCs. Moreover, both LCs and small T-lymphocytes invaded the ductal epithelium forming a lymphoepithelial lesion-like morphology. The present case indicates that LCHs should be added to the different diagnosis for marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type involving the salivary glands.

Langerhans cell histiocytosis in the mandible: Computed tomography and magnetic resonance imaging

Langerhans cell histiocytosis in the mandible is a rare disease. The clinical and advanced imaging features of Langerhans cell histiocytosis in an 18-year-old male are presented. CT images showed an diffuse, ill-defined, expansile lesion of heterogeneous density extending from the anterior mandibular area to the right molar area. CT was particularly helpful in confirming a cortical invasion. T1-weighted gradient echo MR images revealed a heterogeneously low-to high-signal intensity lesion in the right side of the mandible. T2-weighted spin echo MR images showed a heterogeneously iso-to high-signal intensity area with low-intensity areas. Multidirectional MR images revealed the extent of the lesion in the mandibular bone marrow more clearly than CT.
