1/37. Reconstruction of the mandibular condyle using transport distraction osteogenesis.Transport distraction osteogenesis was used to reconstruct the articulation of the temporomandibular joint in two patients. Patient 1 underwent a gap arthroplasty for release of a bony ankylosis. Patient 2 had degenerative joint disease after tumor resection. Both patients had painful, limited mouth opening and facial asymmetry as a result of condylar shortening. A reverse-L osteotomy was performed from the sigmoid notch to the posterior border of the mandible. An external transport distraction device was applied, and the segment was advanced superiorly, 1.0 mm per day, until contact was made with the glenoid fossa. After distraction, the bone was found to have remodeled, inducing a new cortical layer on the articular surface. Additionally, a pseudodisk was generated as a result of the transport distraction. The two patients tolerated the procedure well, returning to pain-free normal mouth opening and being able to masticate regular diets.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/37. Fine needle aspiration cytology of Langerhans cell histiocytosis of the thyroid. A case report.BACKGROUND: Langerhans cell histiocytosis (LCH) of the thyroid is a rare condition, and fine needle aspiration cytology (FNAC) of this entity has rarely been described. CASE: FNAC was done on a 3-cm-diameter thyroid swelling in the left lower lobe of the thyroid gland. Smears showed a large number of lymphocytes, eosinophils, thyroid follicular cells and discrete, large cells with prominent nuclear grooves. Mitotic activity was frequent. A cytologic diagnosis of LCH was offered. Subtotal thyroidectomy was performed, and the cytologic diagnosis was confirmed by histology. CONCLUSION: LCH of the thyroid has certain salient diagnostic features. The presence of histiocytes with prominent nuclear grooves, reactive lymphoid cells and eosinophils along with benign thyroid follicular cells should raise the suspicion of this rare entity on FNAC smears of the thyroid.- - - - - - - - - - ranking = 0.0025228086143658keywords = lower (Clic here for more details about this article) |
3/37. Expression of Fas ligand in Langerhans' cell histiocytosis: A case report of a boy with multisystem involvement.Previous reports of patients with Langerhans' cell histiocytosis have shown characteristics of osteolytic lesion, visceral involvement and organ dysfunction. We report a 2-year-old boy who was diagnosed as Langerhans' cell histiocytosis with a prominent hepatomegaly. X-Radiogram, computed tomography and magnetic resonance imaging revealed the osteolysis of the right iliac bone, the absence of the left eighth rib as well as the right mandible, and an enhancing mass in the left cerebellum. The data of radiography were highly suggestive of Langerhans' cell lineage. The presence of large CD1a-positive mononuclear cells associated with inflammatory cells in peripheral blood smear and bone marrow aspirate further confirmed the diagnosis. In addition, expressions of S100, CD25, CD68, CD80, CD86, and Fas ligand were identified on these cells by immunocytochemical staining. The results indicate that although these cells are activated Langerhans' cells, progression of the disease and the bone destruction could be mediated by the overt FasL expression of the cells.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
4/37. histiocytosis X of the cauda equina.laminectomy, performed on a 46-year-old woman because of weakness and paresthesias of the lower limbs, showed multiple discrete yellow nodules on the nerve roots of the cauda equina. One of these lesions was excised and proved to be a granuloma consistent with the diagnosis of histiocytosis X.- - - - - - - - - - ranking = 0.0025228086143658keywords = lower (Clic here for more details about this article) |

Langerhans cell granulomatosis: a case report of polyostotic manifestation in the jaw.We report the case of a 43-year-old woman who suffered from a polyostotic form of Langerhans cell granulomatosis (LCG) in the mandible and maxilla. The course of the disease was followed for more than 14 years. The disease's progression finally required subtotal resection of the mandible and reconstruction with a microvascular fibula graft. The literature is reviewed for diagnostic and treatment concepts based on the different stages of LCG.- - - - - - - - - - ranking = 2.2773686462246keywords = mandible, jaw (Clic here for more details about this article) |

7/37. Langerhans' cell histiocytosis diagnosed through periodontal lesions: a case report.BACKGROUND: Langerhans' cell histiocytosis (LCH) is a rare disorder in which a neoplastic proliferation of cells similar to the Langerhans' cell of the epidermis is observed. The disease may affect different organs as solitary or multiple lesions with a complete dissemination in different organs such as the bone (jaws), lung, hypothalamus, skin and mucous membranes, lymph nodes, liver, and other tissues. Although LCH is considered a childhood or juvenile disease, the diagnosis is often made in adults, and in many cases, a juvenile form progresses into adult life. hand-Schuller-Christian disease (HSCD) is an LCH form in which the typical lesions Involve the cranial bones, the eyes, and the pituitary gland. methods: This article describes a case of a patient diagnosed, through periodontal lesions and diabetes insipidus, as having Langerhans' cell histiocytosis. CONCLUSION: As far as LCH lesions appearing in periodontal tissues, the periodontist should be involved in the detection of oral lesions.- - - - - - - - - - ranking = 0.069342161556139keywords = jaw (Clic here for more details about this article) |

9/37. Clinico-pathological conference 2002.INTRODUCTION: Six cases are reported, each presented at the 11th Biennial Congress of the International association of Oral Pathologists as an instructive case for differential diagnosis on the basis of clinical, imaging or histological features. CLINICAL PICTURE: Case diagnoses included a large, possibly intraosseous, myofibroma presenting with an oral mass; Langerhans cell histiocytosis with facial skin lesions; an intraosseous vascular hamartoma of the maxilla with worrying radiological features; an unusual mixed radiolucency of the jaw caused by cemento-ossifying fibroma; an osteosarcoma of the posterior mandible causing a well-defined radiolucency and an intraoral squamous cell carcinoma in a child.- - - - - - - - - - ranking = 1.0693421615561keywords = mandible, jaw (Clic here for more details about this article) |
10/37. Solitary Langerhans-cell histiocytosis of the clivus and sphenoid sinus with parasellar and petrous extensions: case report and a review of literature.BACKGROUND: In Langerhans-cell histiocytosis, there occurs an uncontrolled clonal proliferation of dendritic cells that have Langerhans cell like characteristics. In this report, a unique case of a solitary, skull base Langerhans-cell histiocytosis (LCH) is described. CASE DESCRIPTION: A 15-year-old boy presented with raised intracranial pressure, decreased visual acuity, bilateral abducent nerve palsy, and 25% hypoesthesia in all three divisions of the right trigeminal nerve. He had normal strength but with a left-sided upper and lower limb hypertonia and hyper-reflexia and an upgoing plantar reflex. The magnetic resonance (MR) imaging revealed a heterogeneously iso-to hyperintense lesion of the clivus and the sphenoid sinus, extending to the right cavernous sinus to encase the right cavernous internal carotid artery segment, and also involving the right petrous apex and the extradural space in the prepontine region. The lesion was brilliantly enhancing on contrast. An extended frontobasal approach was used to excise the lesion. Following surgery, the residual parasellar and the right petrous apex tumor was treated with a low dose radiation therapy. At follow-up after 1.5 years, there was significant clinical improvement and the computed tomographic scan showed no residual lesion. CONCLUSION: A review of the literature reveals that this is only the second reported case of a spheno-clival LCH. An additional feature includes extensions into the parasellar as well as the petrous apex regions. Despite the extensive spread, the surgical excision with low dose radiation therapy was successful in providing complete resolution of the tumor.- - - - - - - - - - ranking = 0.0025228086143658keywords = lower (Clic here for more details about this article) |
