The article evaluates 12 cases of conservative treatment of displaced mandibular fractures in adults. Twelve cases of displaced mandibular fractures treated surgically, either by closed reduction (IMF) or open reduction internal fixation (ORIF) served as controls. Occlusion, maximal mouth opening, lateral jaw movements, neurological dysfunction (=sensory deficit), and bone remodeling were evaluated and scored in both groups, and results were compared. No significant differences were found between the two groups in all the evaluated parameters. It is concluded that in certain cases, with displacement of 2 - 4 mm, where a surgical approach is not feasible, reasonable spontaneous reduction and bone remodeling can occur. Meticulous follow-up is mandatory.

Spindle-cell lipoma (SCL) is a variant of lipoma, usually presenting in the neck or trunk. SCL of the oral cavity is rare. Some cases of oral SCL have been reported;however, the clinico-pathologic characteristics of oral SCL are still unknown. Here we report on 2 cases and review 33 cases of oral SCL published in the literature. The patients were 23 men and 12 women, with a mean age of 55 years (range 23 - 88 years);there were no children. Tumor sites included: tongue (n = 13), cheek/buccal mucosa (n = 11), floor of mouth (n = 5), lip (n = 2), hard palate (n = 2), alveolar ridge (n = 1), and maxilla (n = 1). The mean tumor size was 20.87 mm (range 3 - 50 mm), smaller than extra-oral lesions. Thirty-three patients (94%) presented with a single lesion that was circumscribed and composed of mature adipocytes admixed with bland spindle cells. The spindle cells were strongly immunoreactive for CD34, whereas the adipocytes were negative. The main differential diagnosis is atypical lipoma/well-differentiated liposarcoma. All lesions underwent local excision and recurrences are rare. Oral SCL do not seem to differ from their extra-oral counterpart, which are much more common and larger in size. SCL should be included in the differential diagnosis of oral cavity mesenchymal tumors.

Background: Epstein Barr Virus (EBV) is associated with different kinds of tumors. In the present study we tried to understand its role in pediatric MDS of a 4-year-old girl with EBV infection and MDS with refractory anemia and monosomy 7. Procedures: The work-up included: hematological tests;serology for IgM, IgG antibodies to EBV;PCR for EBV;cytogenetics of bone marrow (BM), and FISH analysis of BM and blood;immunohistochemistry-LMP1 expression on BM smears. Results: Hematological follow up showed constant mild dysplastic changes mostly in the erythroid lineage. PCR for EBV showed positive results in the nasopharygeal smears as well as in blood 15 weeks after disease onset. Cytogenetic analysis showed monosomy7 inall the mitoses of BM sample. Fluorescence in situ hybridization (FISH) showed monosomy 7% in 57% of the cells, followed by a decreased tendency in the percentage of monosomy 7 cells in both BM and blood. Immunohistochemistry for EBV-latent membrane protein 1 (LMP-1) on the patient’s BM smears, 21 weeks post disease onset, showed 9% positive cells, 80% of them carried monosomy 7. Conclusion: The parallel occurrence of the EBV infection and MDS, as well as the continuous EBV PCR positive and monosomy 7, support the possibility that they are related.
