The tumors of intrathyroidal epithelial thymoma are a rare group of thyroid neoplasms.of this , spindle epithelial tumor with thymus like differentiation (SETTLE) has been a rare entity reported only 17 times in English literature. A 34-year-old man had an enlarged thyroid for all of his adult life. Over a period of 12 weeks before hospitalization, the thyroid was noted to enlarge rapidly. Hist...

Abstract Introduction/Objective Uterine leiomyosarcoma is a malignant neoplasm with three distinct histologic subtypes: spindle, epithelioid, and myxoid. Distinguishing from mesenchymal uterine neoplasms such as endometrial stromal sarcoma can be challenging they may exhibit similar histology immunohistochemical profile. In cases, molecular studies help achieve the definitive diagnosis. It has ...

Background: In vitro maturation can have deleterious effects on spindle formation and proper chromosome alignment in human oocytes and can be profoundly affected by culture conditions. This study compared the spindle presence and location with the maturation rate Abstracts of the 12th Royan International Congress on Reproductive Biomedicine 3 1 International Journal of Fertility & Sterility (IJ...

A dog presented with a retrobulbar mass, diagnosed histopathologically as malignant spindle cell neoplasia. Emergence of analogous findings in the contralateral orbit prompted extended immunohistochemistry of the original mass and reassignment to idiopathic sclerosing orbital inflammation. Early incisional biopsy with extended immunohistochemical analysis should be considered for canine orbital...

purpose: to assess the histopathological and immunohistochemical features of orbital spindle cell tumors. methods: a descriptive, retrospective study was performed on 63 pathology reports on all types of orbital spindle cell tumors at the pathology department of farabi hospital between 1995 and 2005. immunohistochemistry studies for different markers, such as smooth muscle actin, desmin, s100 p...

a set of one hundred and twenty nine patients with known primary malignancy and suspected brain metastasis was reviewed in present study. the patients were selected among patients presented to the mri section of imam khomeini hospital or a private mri center in tabriz (iran). primary tumor site, clinical manifestations, number and site of lesions were identified in this patient population. the ...

introduction: solitary fibrous tumor is a rare, mesenchymal neoplasm that has been reported in numerous sites. occurrence in the parotid gland is exceedingly rare.   case report: a 53-year-old man with a 2 cm solitary fibrous tumor of the left parotid gland, that was observed clinically and operatively and thought to be a neoplasm arising from stensen's duct, is described. a pre-operative ...

Dimensional accuracy in machined parts depends on the precision of spindle, which is highly affected by applied forces, itself. This precision of spindle becomes more serious when it is used for a period of long times. Therefore, stress and strain analysis of spindle is very important in the behavior and preservation of its precision. In this paper, the forces applied to the spindle of a turnin...

abstract background: abdominal tumors are still a diagnostic problem in children. this study was conducted to assess the presentation and types of childhood intra abdominal tumors in children in shiraz. materials and methods: participants of this historical cohort study consisted of 298 children aged between 1.5 months to 15 years old who were diagnosed with abdominal mass between march 2003 an...
