BACKGROUND Malignant Struma Ovarii is a rare ovarian neoplasm that is usually asymptomatic and infrequently diagnosed preoperatively. A few case studies have described associated thyrotoxicosis. CASE A 46-year-old female presented for her annual gynecologic exam during which a pelvic mass was appreciated on physical examination. Patient was asymptomatic(More)
A patient with retroperitoneal and axillary lymphadenopathy and splenomegaly was demonstrated histologically to have the hyaline vascular type of giant lymph node hyperplasia, with plasma cell infiltrates in each region. The abdominal lesions were not surgically resectable and did not respond to radiotherapy. The clinical findings included polyclonal(More)
OBJECTIVE To describe the pattern and frequency of oncogene mutations in white and African American women with endometrial cancer and to determine if racial differences in oncogene mutations exist among women with pathologically similar tumors. METHODS Patients with endometrial cancer from a large urban hospital were identified through medical records,(More)
Spontaneous tumor involution in ovarian stromal tumors is a poorly understood phenomenon. In this report, we describe a rare case of luteinized thecoma that showed extensive involutional changes, such that cellular elements diagnostic of luteinized thecoma were sparse. The convoluted contour of the tumor resembled that observed in a corpus albicans;(More)
Background/Objectives:The aim of this study was to determine the diagnostic performance of body mass index (BMI) and to detect the optimal BMI cutoff points to define adiposity in women of various ages.Subjects/Methods:A total of 2409 women participated. Fat mass was measured using a multifrequency bioelectrical impedance analysis. The diagnostic(More)
OBJECTIVE Gestational and non-gestational choriocarcinomas have distinctly different tissues of origin, parental genotypes, natural histories, and responses to therapy. Our objective was to develop a convenient, fast, and reliable assay that would, using only patient tissue, allow separation of gestational from non-gestational choriocarcinomas. METHOD(More)
Odontogenic ghost cell tumor is a rare, neoplastic form of calcifying odontogenic cyst (Gorlin cyst) whose cytologic features have not been previously reported. We present a case of odontogenic ghost cell tumor diagnosed by fine-needle aspiration biopsy (FNAB). The aspirate was characterized by (1) tissue fragments with basaloid epithelial cells, (2)(More)
BACKGROUND Human papillomavirus (HPV) is the major risk factor for cervical cancer. METHODS We implemented a retrospective case-series study to discern HPV knowledge accuracy among women diagnosed with and treated for cervical cancer. Cases (n=1174), identified from the Pathology database, were diagnosed and treated for cervical cancer at the same(More)
