颌骨郎格罕细胞组织细胞增生症的临床病理及免疫组化研究

目的研究慢性局限性郎格罕细胞组织细胞增生症（Ｌａｎｇｅｒｈａｎｓｃｅｌｈｉｓｔｉｏｃｙｔｏｓｉｓ，ＬＣＨ）的组织病理学及免疫组织化学特点。方法ＨＥ染色及组织学观察，有丝分裂计数和免疫组织化学染色。结果本项研究包括２２例ＬＣＨ。ＨＥ染色见郎格罕细胞（ＬＣ）核因扭曲而呈现多样性，核分裂并不少见（平均每１０个高倍视野７．１个核分裂像）。片状排列的细胞间可见明显不规则的细胞间隙。免疫染色见ＬＣＳ－１００阳性，增殖细胞核抗原（ＰＣＮＡ）阳性率平均为１４．５％，病变中还散在ＣＤ６８及组织蛋白酶Ｄ阳性的组织细胞，淋巴细胞以Ｔ细胞为主。结论上述结果提示，ＬＣ细胞核形态的多样性及细胞排列是诊断本病的基础；该病变的性质是ＬＣ增殖而不是ＬＣ单纯聚积，可能属于肿瘤性增生；病变中的ＬＣ属不成熟的ＬＣ前体细胞。

Langerhans' cell histiocytosis of the jaw bones. Report of 11 cases

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.

Oral mucosal involvement in Langerhans' cell histiocytosis: long-term follow-up of a rare case

Langerhans' cell histiocytosis (LCH) is a rare disease where different organs and systems may be affected. Oral involvement generally consists of mucosal ulceration associated with lesions of the underlying bone. Many reports exist about the misdiagnosis of this disease. Various symptoms may lead the clinician to an incorrect diagnosis, especially with multiple organ involvement. Oral manifestations are common, and dentists should be aware of this disease and evaluate intraoral findings accordingly. This study presents an LCH case characterized by oral mucosal ulcerations with no involvement of the underlying bone. A definitive diagnosis was made by open biopsy from the oral mucosa.     

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.
