[ spindle cell myoepithelioma of parotid gland: a case report]

Background: Myoepthelioma is a rare salivary gland tumor which is usually located in parotid gland and in minor salivary glands

Case report :We report a case of myoepithelioma arising in an accessory paritid gland in a 47-yearold woman who presented with a slowly expanding subcutaneous nodule on the left cheek, that was within the parotid gland at surgical resection . This tumor was composed of spindle cells. Immunophenotypical characterization demonstrated its myoepithelial nature

Conclusion: In the subcutaneous tissue, this unusual neoplasm may be confused with soft tissue tumors showing spindle cell features

Giant lipoma of the transverse colon: a case report and review of the literature

Colonic lipomas are benign adipose tumors which are usually submucosal. Small lesions are asymptomatic and may be detected incidentally. Large lipomas can cause symptoms. We report a case of symptomatic giant colonic lipoma. A 67-year old woman was admitted to hospital with persistent abdominal pain, for which a barium enema showed a large polypoid mass occluding the lumen of the transverse colon. Colonoscopy revealed a tumor narrowing the bowel lumen of about 5 cm in diameter with a sessile appearance and ulcerated overlying mucosa. The possibility of colonic malignancy could not be precluded and an operative resection was performed. Pathological examination revealed a colonic lipoma. Twelve months after the surgery, the patient was free of symptoms. Awareness of the possibility of colonic lipomas is important for clinicians in terms of evaluation of therapeutic regimen

[Cytologic study of 8827 PAP smear with cytosistologic confrontation]

Cervical cancer is the second female cancer. Currently, pap smears represent the most effective tool for screening of neoplastic cervical lesions and their precursors. The objective of this study is to deal with epidemiology, cytology and histology of all cervical lesions and to evaluate pap smears reliability in cervical cancer screening. Our study included 8827 pap smears collected during three years [2003-2005]. Results of pap smears were reported according to the 2001 Bethesda system. A comparative cytohistologic study was performed in 342 cases. For statistical analysis, we used Chi 2 test and considered differences as significant for a p value less than 0,05. The mean age of our patients was 41 years. Pap smears were normal in 269 cases [3,1%], inflammatory in 8070 cases [9]4%] and showed epithclial cell defects in 46 cases [0,5%]. A cytohistologic accord was found in 944%of cases. Pap smear was more sensitive in detecting high grade squamous lesions [50 to 100%] than those of low grade [33,3 to 66,6%]. Pap smear is the most useful tool for screening of preneoplastic cervical lesions which tend to be mole and more a pathology of young females. Its sensibility and specificity are better in detecting high grade intraepithelial lesions
