Thirty-one patients with spinal tumors underwent reconstructive surgery with our spinal instrumentation system (MPDS and MADS), with or without our new vertebral tumor prosthesis. The characteristics of the spinal tumors were analysed statistically and the treatment outcome was evaluated. There were 4 benign tumors, 6 malignant tumors, and 21 metastatic tumors. The malignant tumors involved the...
Background & Aim: Gastrointestinal stromal tumors(GISTs) are the most common mesenchymal tumors of gastrointestinal tract. They are known to express c-kit, which is important in their diagnosis and treatment. The aim of our study was to assess the morphologic and immunohistochemical features of gastrointestinal stromal tumors and the significance of c-kit expression in them. Materials and M...
cytomegalovirus (cmv) is a widespread pathogen that is found in milk, saliva, urine, cervical secretions, and semen fluid. it is supposed that cmv is a risk factor for breast cancer. the aim of this study was to determine the frequency of cmv among benign and malignant breast tumors. paraffin embedded breast carcinoma (n=24) and fibroadenoma (n=24) samples were collected from toos and firoozgar...
Epidermoid cyst is a benign lesion and accounts for approximately 1 per cent of all testicular tumors. It cannot be differentiated from the other tumors on clinical bases. We report case epidermoid testis make brief review world literatura.
OBJECTIVE To distinguish between benign and malignant peripheral nerve sheath tumors around the pelvis. METHODS A retrospective study of 30 patients with benign and malignant peripheral nerve sheath tumors located around the pelvis was performed. Clinical, imaging and histological features of 19 benign and 11 malignant peripheral nerve sheath tumors around the pelvis were reviewed retrospecti...
Benign neoplasms of the colon, rectum, anus and anal canal are true neoplasia colon mucosa associated with a high risk colorectal cancer (CC). The literature review analyzes epidemiology, factors, modern methods diagnosis treatment, describes priority minimally invasive interventions for benign tumors.
Introduction: cyclooxygenase-2 (COX-2) is involved in pathogenesis of various tumors and possibly malignant skin tumors including malignant melanoma; however, there is not enough information about COX-2 expression in benign melanocytic lesions. In the present study we compared the expression levels of COX-2 in malignant melanoma and benign melanocytic lesions. Method: In this analytical study, ...
in 30 patient with single cold thyroid nodule and normal thyroid function tests, 99mtc-mibi scan is performed. the nodules are divided to hot (10), warm (12) and cold (8). fna reported papillary ca in 4, suspicious follicular neoplasm in 3 and 23 benign lesions. 7 patients were operated on and had final pathology reports (4 papillary ca and 3 benign lesions). all the nodules with no mibi uptake...
granular cell tumor is a rare benign neoplasm most commonly appears in the head and neck region, especially in the tongue, cheek mucosa, and palate. occurrence in limbs is even rarer. these tumors account for approximately 0.5% of all soft tissue tumors. granular cell tumor can also affect other organs including skin, breast, and lungs. local recurrence and metastasis is potentially higher in m...
odontogenic tumors constitute a group of heterogeneous lesions of benign and malignant neoplasms with variable aggressiveness. ameloblastomas are a group of benign but locally invasive neoplasms that occur in the jaws and are derived from epithelial elements of the tooth-forming apparatus. we previously described orosomucoid-1 protein expression in odontogenic myxomas. however, whether orosomuc...
