INTRODUCTION Ovarian cancer (OC) is the third most common gynecologic malignancy worldwide. Most of cases it is of epithelial origin. At the present time there is not a standardized screening method, which makes difficult the early diagnosis. The 5-year survival is 90% for early stages, however most cases present at advanced stages, which have a 5-year(More)
BACKGROUND Melanoma of the vulva is the second most common vulvar cancer after epidermoid carcinoma. Patients suffering from this disease usually present with a late-stage disease with a poor prognosis. The prognostic factors reported in previous studies are not homogeneous and the clinical/pathogenic role of c-KIT expression is not clear. Breslow staging(More)
AIM We investigate if body mass index (BMI, kg × m(2)) is related to clinical-pathological characteristics in primary tumor and disease outcome in endometrial cancer. BACKGROUND Endometrial cancer incidence is increasing in industrialized countries. High BMI is associated with worse prognosis for many diseases. INTRODUCTION Endometrial carcinoma is the(More)
The diagnosis of low-grade and pseudosarcomatous spindle cell lesions of skin and soft tissue can sometimes be problematic; in particular, distinction between fibroblastic, myofibroblastic, and smooth muscle proliferations can occasionally pose difficulties on routine histologic examination. We have applied a panel of immunohistochemical markers to a series(More)
INTRODUCTION Endometrial cancer (EC) is the second most common gynecologic malignancy worldwide in the peri and postmenopausal period. Most often for the endometrioid variety. In early clinical stages long-term survival is greater than 80%, while in advanced stages it is less than 50%. In our country there is not a standard management between institutions.(More)
INTRODUCTION About 5% of ovarian cancers are so poorly differentiated and difficult to classify that they are called undifferentiated carcinomas and usually have disseminated disease at presentation. Extra pelvic debulking it is difficult to complete. PRESENTATION OF CASE We report a case of a rare ovarian tumor presented as a large mesenteric tumor of(More)
Neuroendocrine carcinomas of the pancreas are rare neoplasms whose morphologic features generally mirror those seen in neuroendocrine tumors in other organs. Rarely, however, they may display unusual morphologic appearances that can introduce difficulties for diagnosis. We report four cases of primary neuroendocrine carcinomas of the pancreas (islet cell(More)
Thyroid hyperplasia is a physiologic response of follicular epithelium to hormonal changes that result in disturbances in the feedback mechanism of thyrotropin-releasing hormone and thyroid-stimulating hormone. The most common manifestation of this process is the so-called sporadic goiter (diffuse or nodular hyperplasia), a condition that may be associated(More)
