1/182. Characterization of human MMTV-like (HML) elements similar to a sequence that was highly expressed in a human breast cancer: further definition of the HML-6 group.Previously, we found a retroviral sequence, HML-6.2BC1, to be expressed at high levels in a multifocal ductal breast cancer from a 41-year-old woman who also developed ovarian carcinoma. The sequence of a human genomic clone (HML-6.28) selected by high-stringency hybridization with HML-6.2BC1 is reported here. It was 99% identical to HML-6.2BC1 and gave the same restriction fragments as total dna. HML-6.28 is a 4.7-kb provirus with a 5'LTR, truncated in RT. Data from two similar genomic clones and sequences found in GenBank are also reported. Overlaps between them gave a rather complete picture of the HML-6.2BC1-like human endogenous retroviral elements. work with somatic cell hybrids and FISH localized HML-6.28 to chromosome 6, band p21, close to the MHC region. The causal role of HML-6.28 in breast cancer remains unclear. Nevertheless, the ca. 20 Myr old HML-6 sequences enabled the definition of common and unique features of type A, B, and D (ABD) retroviruses. In Gag, HML-6 has no intervening sequences between matrix and capsid proteins, unlike extant exogenous ABD viruses, possibly an ancestral feature. Alignment of the dUTPase showed it to be present in all ABD viruses, but gave a phylogenetic tree different from trees made from other ABD genes, indicating a distinct phylogeny of dUTPase. A conserved 24-mer sequence in the amino terminus of some ABD envelope genes suggested a conserved function.- - - - - - - - - - ranking = 1keywords = breast (Clic here for more details about this article) |
2/182. A case of simultaneous presence of primary endometrial carcinoma and metastasis of a breast carcinoma to the ovary after 5 years of tamoxifen therapy.We report a case of a 43-year-old woman with the simultaneous presence of a primary uterine endometrial cancer and metastasis of breast cancer to the ovary after 5 years of tamoxifen therapy. tamoxifen therapy lengthens recurrence-free survival of the patient. However, the risk of endometrial cancer and the possibility of recurrence of breast cancer also must be considered.- - - - - - - - - - ranking = 1keywords = breast (Clic here for more details about this article) |
3/182. Ovarian carcinoma metastatic to bilateral axillary lymph nodes. A case report.BACKGROUND: Ovarian cancer is a major cause of cancer deaths in women and usually presents with diffuse abdominal disease. Lymph node metastases are common, but axillary lymph nodes are rarely involved. CASE: A 63-year-old woman, initially presenting with abdominal symptoms and massive ascites, underwent optimal cytoreduction followed by intravenous chemotherapy with paclitaxel and carboplatin. The patient subsequently underwent a second-look surgery revealing only microscopically positive disease and then received intraperitoneal chemotherapy with cisplatin. At a follow-up visit, she was found to have bilateral axillary lymph node enlargement. mammography revealed no lesions in either breast. Fine needle aspiration dissection confirmed the diagnosis of metastatic, recurrent ovarian adenocarcinoma and subsequently axillary lymph node dissection was undertaken. CONCLUSION: Ovarian carcinoma, which usually follows typical patterns of metastatic involvement, can appear in unusual areas.- - - - - - - - - - ranking = 0.16666666666667keywords = breast (Clic here for more details about this article) |
4/182. Metastasis of a breast carcinoma in a mature teratoma of the ovary.Metastatic tumors in ovaries from breast carcinoma are well known. breast carcinoma metastases in primary ovarian tumors are much more uncommon. The authors present a case of a primary breast carcinoma, with a lobular component (signet ring cells), which metastasized into a mature cystic teratoma of the ovary. The problem of differential diagnosis with other primary ovarian tumors or metastatic tumors and the problem of particular behavior of metastatic lobular components are discussed.- - - - - - - - - - ranking = 1keywords = breast (Clic here for more details about this article) |
5/182.

6/182. Synchronous inflammatory breast cancer and advanced ovarian carcinoma: a case with prolonged disease-free survival.Despite the known association of these malignancies, the incidence of a synchronous presentation of breast and ovarian cancer is low, and the current literature does not address an approach to this clinical problem directly. We report a greater than 2.5 year disease-free survival in a patient treated for synchronous stage IIIB inflammatory breast cancer and stage IIIC epithelial ovarian cancer. The prolonged disease-free survival in our case may provide some guidance in this unusual clinical situation.- - - - - - - - - - ranking = 1keywords = breast (Clic here for more details about this article) |

8/182. Bilateral inflammatory breast metastases of epithelial ovarian cancer.Metastases to the breast are rare. Secondary breast involvement from an epithelial ovarian cancer heralds widespread dissemination and a very poor prognosis. We report an unusual case of a patient who had epithelial ovarian cancer and who showed signs of recurrence with inflammatory metastases to both breasts, 2 years after her diagnosis of ovarian cancer. She died within 3 months of breast involvement. Our case has unique features, with both bilateral breast metastases and also with its inflammatory pattern of metastasis, which is extremely rare.- - - - - - - - - - ranking = 1.5keywords = breast (Clic here for more details about this article) |
9/182. Collagenous spherulosis mimicking keratinizing squamous metaplasia in a borderline endometrioid tumour of the ovary.AIMS: Collagenous spherulosis (CS) is a rare lesion which is an incidental finding in breast and salivary glands. It is characterized by fibrillar spherules exhibiting an intrinsic radiating or concentric pattern which are surrounded by myoepithelial cells. This entity can be misdiagnosed as adenoid cystic carcinoma and in-situ ductal carcinoma. methods AND RESULTS: We report here the first case of CS arising in a borderline endometrioid tumour of the ovary where it merged with squamous metaplasia. CONCLUSION: This observation illustrates another pitfall of CS which can be misidentified as keratin pearls. The pathogenesis remains unclear but it has been claimed that the accumulation of basement membrane material may be due to the proliferation of pre-existing myoepithelial cells that secrete matrix components. Since ovarian tumours do not contain myoepithelial cells, one should assume that the epithelial cells differentiate towards myoepithelial cells as it has been shown in vitro and ex vivo.- - - - - - - - - - ranking = 0.16666666666667keywords = breast (Clic here for more details about this article) |
10/182. Anti-Yo positive paraneoplastic cerebellar degeneration associated with ovarian carcinoma: case report and review of the literature.paraneoplastic cerebellar degeneration (PCD) is a rare nonmetastatic neurological complication in cancer patients. Anti-Yo is one of the anti-onconeural antibodies found in PCD patients. It is believed that anti-Yo occurs almost always in women and is most likely associated with gynecologic or breast cancers, although exceptions exist. Here we report a PCD patient with ovarian cancer having high-titer anti-Yo. The acute onset of her PCD symptoms mimicked that of a stroke. Her ovarian cancer tissue contained abundant plasma cells and lymphocytes. After a thorough review of the literature, we propose a schematic hypothesis for the autoimmune pathogenesis of PCD. Despite anecdotal case reports of neurological improvement with different combinations of treatment, including IVIg, there is still no definitely effective treatment for PCD. Further research on the pathogenesis of PCD may lead to more effective therapies.- - - - - - - - - - ranking = 0.16666666666667keywords = breast (Clic here for more details about this article) |
