The aim of this study was to describe the imaging features of neuroendocrine differentiated breast carcinoma (NEDBC) and to correlate the radiological findings with the clinical and histopathological findings. A retrospective review of the mammograms of 1845 histopathologically proven breast cancer cases revealed five NEDBC. The clinical, imaging, and(More)
UNLABELLED Some primary carcinomas of the breast have been classified as neuroendocrine. In this paper we report on 12 cases of neuroendocrine carcinoma of the breast displaying common and uncommon histological features. MATERIALS AND METHODS All patients were aged from 43 to 79 (median 66.5) years. The tumors were unilateral and ranged from 0.8 to 7 cm(More)
Breast cancer with choriocarcinomatous features is rare. This report describes four cases of breast cancer with choriocarcinomatous features. The tumor cells were positive for human placental lactogen (hPL) and human chorionic gonadotropin (hCG) by immunohistochemistry. The cases reported in the literature had a poor prognosis and the patients died within a(More)
OBJECTIVE The purpose of our study was to investigate the imaging features of invasive micropapillary carcinoma of the breast, which is a recently described, rare variant of infiltrating ductal carcinoma. CONCLUSION Invasive micropapillary carcinoma of the breast usually manifests as a firm, immobile mass. Findings on mammography are of a spiculated,(More)
OBJECTIVE To evaluate the mammographic and ultrasonographic findings of sclerosing adenosis, a relatively uncommon entity which may sometimes mimic carcinoma. MATERIALS AND METHODS A retrospective review of the records of 33,700 women, who have undergone mammographic examination at our institution between January 1985 and July 2001 revealed 43(More)
Male breast cancer is rare. The most common histological subtypes include invasive carcinoma "of no special type" and papillary carcinoma. Other variants, including pure micropapillary carcinoma, have been described as well but are extremely rare. Pure micropapillary carcinoma has been recently characterized by a C-MYC gene amplification in women. We report(More)
AIM To determine the effect of paclitaxel and cisplatin in the reduction of primordial follicular reserve in rat. MATERIAL AND METHODS Thirty young female rats were divided randomly into three groups of 10 rats each. Paclitaxel 7.5 mg/kg and cisplatin 5 mg/kg were administered intraperitoneally in a single dose sterile technique to paclitaxel (n=10), and(More)
We have reviewed the histopathological, clinical outcome and immunohistochemical status in 21 women with cystosarcoma phyllodes (CSP) tumors of the breast. We assessed 12 tumors as histopathologically benign and 9 tumors as malignant. The median patient ages in benign and malignant CSP tumors were 39.6 and 45.4 years of age, respectively. The stromal(More)
Inhibin is a heterodimeric protein hormone that appears to be a sensitive immunohistochemical marker of sex cord-stromal tumors. Although sex cord-stromal tumors can usually be distinguished from ovarian epithelial tumors or their metastases by morphology or by using antibodies against intermediate filaments, the diagnosis remains difficult in rare(More)
Large cell neuroendocrine carcinoma is a rare aggressive cervical neoplasm, considerably rarer than the well-recognized small cell neuroendocrine carcinoma of the cervix. Cervical large cell neuroendocrine carcinomas are distinctive cervical carcinomas that are frequently misdiagnosed and have an unfavorable outcome, similar to that of small cell carcinoma.(More)
