1/26. The use of microsatellite instability in the distinction between synchronous endometrial and colonic adenocarcinomas.The association of endometrial carcinoma with other gynecologic neoplasms, especially ovarian and fallopian tube carcinoma, has been well documented and is usually interpreted as a result of a field defect. Sporadic synchronous primary carcinomas occurring in the endometrium and colon are extremely rare, especially in the absence of the familial genetic abnormalities seen in hereditary nonpolyposis colorectal carcinoma (HNPCC) syndrome, and may present a diagnostic dilemma. Two cases of synchronous adenocarcinomas of the endometrium and colon were studied for genetic abnormalities and differences to test for the presence of two primary tumors. Primary tumors, metastases, and normal tissues were microdissected from formalin-fixed, paraffin-embedded tissues. PCR amplification was performed for microsatellite DNA markers on chromosome 17q and 11q13. The colonic tumors were moderately and poorly differentiated, invasive, nonmucinous adenocarcinomas, whereas one uterine tumor was endometrioid adenocarcinoma and the other was papillary serous carcinoma. Although microsatellite instability, as evidenced by changes in the lengths of the amplified PCR products, was detected at 17q and 11q13 loci in the uterine and colonic neoplasms, the patterns of instability differed between the two primary tumor sites. Moreover, the lymph node metastasis in one colonic tumor had genetic alterations that differed from that of the primary tumor. In both patients, the molecular studies suggested the presence of two synchronous primary tumors. Molecular techniques may assist in distinguishing two separate primaries by determining the contraction and expansion of microsatellite regions in DNA obtained by microdissection from the primary tumors and associated metastases.- - - - - - - - - - ranking = 1keywords = gynecologic (Clic here for more details about this article) |
2/26. Metachronous carcinoma of the vulva and fallopian tube.BACKGROUND: Metachronous carcinoma of the vulva and fallopian tube is an unusual co-occurrence of gynecological malignancies. A report of such a case that developed and recurred over a 7-year period is presented. CASE: A 53-year-old G3P3 female presented with a verrucous carcinoma of the vulva and a serous papillary adenocarcinoma of the left fallopian tube metachronously. To investigate a possible association between the co-occurrence of the rare neoplasms and factors associated with multiple gynecological malignancies, we analyzed the status of human papillomavirus infection and dna mismatch repair deficiency as indicated by microsatellite instability. All samples analyzed were negative for these factors. CONCLUSION: The present results support the possibility that metachronous carcinomas of the vulva and fallopian tube involve unknown etiological factors or arise independently.- - - - - - - - - - ranking = 2keywords = gynecologic (Clic here for more details about this article) |
3/26. Coexistent choriocarcinoma and malignant mixed mesodermal tumor of the uterus.OBJECTIVE: The purpose of this article is to report a case of coexisting uterine choriocarcinoma and uterine malignant mixed mesodermal tumor (MMMT). The relevant literature is reviewed and possible pathogenesis discussed. methods: The clinical course and histopathology of the case were reviewed and a medline literature search for other cases was performed. RESULTS: The patient's uterine tumor contained syncytiotrophoblastic and cytotrophoblastic cells that stained positively for the beta subunit of human chorionic gonadotrophin consistent with uterine choriocarcinoma. pathology also revealed a second distinct neoplasm composed of adenocarcinoma admixed with sarcoma, compatible with a uterine MMMT. The patient experienced metastatic choriocarcinoma to her lungs, lymph nodes, and brain. She suffered a complicated clinical course and died 7 months after her initial diagnosis. The literature search revealed that various gynecologic and nongynecologic carcinomas with trophoblastic differentiation have been described, but an association with uterine MMMT has not been previously reported. CONCLUSIONS: Trophoblastic differentiation and choriocarcinoma associated with gynecologic and nongynecologic tumors is rare. We document the presence of uterine MMMT coexisting with uterine choriocarcinoma that followed an aggressive clinical course and review the possible pathogenesis of this lesion.- - - - - - - - - - ranking = 4keywords = gynecologic (Clic here for more details about this article) |
4/26. Two cases of coincident carcinomas of the head and neck and the uterine cervix.BACKGROUND: Human papillomavirus (HPV) is an independent risk factor for select head and neck carcinomas and most uterine cervix carcinomas. We report two patients with synchronous diagnoses of cervical cancer and HPV-related head and neck cancer. CASE: One patient was a 53-year-old woman with regionally metastatic tonsillar carcinoma treated surgically and with adjuvant radiation. Abnormal vaginal bleeding developed. Gynecologic examination showed advanced cervical carcinoma. The other patient was a 78-year-old woman surgically treated for carcinoma of the left anterior nose. Five months later, symptoms of recurrent nasal carcinoma and concurrent vaginal bleeding developed. Gynecologic examination showed advanced cervical carcinoma. CONCLUSIONS: These cases of coincident tumors demonstrate possible systemic susceptibility to the carcinogenic effects of HPV. The common association of HPV with both uterine cervix cancers and select head and neck cancers should prompt early evaluation of gynecologic or upper aerodigestive tract symptoms for patients with known HPV-related cancers.- - - - - - - - - - ranking = 1keywords = gynecologic (Clic here for more details about this article) |
5/26. Synchronous renal cell carcinoma and gynecologic malignancies.BACKGROUND: Synchronicity of renal cell carcinoma and gynecologic malignancies is a rare condition and standardized treatment does not exist. CASES: Three cases of synchronous renal cell carcinoma and gynecologic malignancies are described. All three cases underwent optimal cytoreductive surgery for the gynecologic malignancy and a radical nephrectomy for the renal cell carcinoma. Adjuvant treatment, after surgery, was individualized in each case. Estrogen and progesterone receptors were positive in all the gynecologic tumors but negative in the renal cell tumors. CONCLUSIONS: This is apparently the largest report of synchronous renal cell carcinoma and gynecologic malignancies. Despite this rare condition, surgery should still be considered as primary treatment for these patients.- - - - - - - - - - ranking = 9keywords = gynecologic (Clic here for more details about this article) |
6/26. Multiparameter flow cytometry in the diagnosis of a gynaecologic double tumor: a case report.PURPOSE. An uncommon clinical presentation of metastatic tumor will often lead to additional diagnostic examinations. The patient of the present study was known to have endometrial cancer which was thought to be limited to the endometrium. Three months postoperatively, she developed ascites due to spread of the tumor, which is rarely seen in low-stage endometrial cancer. METHOD. Multiparameter flow cytometry using both cell phenotype information and DNA ploidy was performed. RESULTS. Retrospectively, the patient was diagnosed as having a DNA-diploid epithelial tumor of the endometrium as well as a DNA-aneuploid epithelial tumor in the left fallopian tube. It was shown that 3 months after primary surgery she developed ascites caused by metastatic tumor from the primary fallopian tube cancer. CONCLUSION. The complete diagnosis was made using multiparameter flow cytometry which, at present, is not routinely applied in gynecologic pathology.- - - - - - - - - - ranking = 1keywords = gynecologic (Clic here for more details about this article) |
7/26. Clinical importance of molecular determinations in gynecologic patients with multiple tumors.BACKGROUND: The prognosis and treatment of patients with multiple tumors may depend on the correlation between tumors: multiple primary tumors, or recurrent tumors, and metastatic disease. The authors investigated whether the detection of molecular aberrations in multiple gynecologic tumors in individual patients provided clinically useful information on the correlation between the tumors. methods: Between 1999 and 2001, molecular analyses were performed on tissue from 15 gynecologic patients, all with multiple tumors. The molecular analyses included loss of heterozygosity determinations at eight DNA loci and mutation analyses of p53 exons 5-8 using the single-strand conformation polymorphism method. Previously, it was not possible to use routine diagnostic histopathology to determine accurately the correlation between multiple lesions in patients with gynecologic malignancies, information that may have an impact on clinical decision-making and prognosis. RESULTS: Molecular results were obtained from all tumors from each of the 15 patients. The DNA alterations detected provided evidence that two patients had second primary tumors, nine patients had a single tumor with metastases, and four patients had two independent primary tumors as well as metastatic disease. The results provided additional diagnostic information and contributed to clinical decision-making. CONCLUSIONS: The authors demonstrated that, by comparing DNA alterations in multiple tumors within an individual patient, evidence about correlations between the tumors can be obtained. These investigations can be performed on routinely processed tissues, and the results may be of clinical importance in helping to determine the management or prognosis of patients with gynecologic malignancies.- - - - - - - - - - ranking = 8keywords = gynecologic (Clic here for more details about this article) |
8/26. A case with multiple gynecological malignancies.A patient with cervical non-Hodgkin lymphoma was treated with chemotherapy. Fourteen months after the diagnosis of the lymphoma, an endometrial adenocarcinoma was detected as a secondary malignant tumor. The patient was treated with surgery followed by radiotherapy. Approximately 7 years after the diagnosis of endometrial cancer, vaginal invasive squamous cell carcinoma was diagnosed as the third primary malignancy, and a second-line palliative radiotherapy was applied. Seven months after the last radiotherapy, postradiational sarcoma in the vagina was diagnosed. Congenital and acquired immune system disorders, viral oncogenes, and various human leukocyte antigen (HLA) types were investigated. Total blood count and lymphocyte subset analysis were performed, and CD4 lymphopenia was detected. serologic tests were carried out for human immunodeficiency virus, hepatitis b virus, human papillomavirus, Epstein-Barr virus, and herpes simplex virus infection. Epstein-Barr virus viral capsid antigen IgG was found positive. Low-risk human papillomavirus panel was detected by Hybrid Capture method in the cervical smear. The HLA investigation revealed HLA-A2, HLA-A3, HLA-B57, HLA-B35, HLA-B4, HLA-B6, HLA-DR3, HLA-DR1, HLA-DR51, HLA-DR52, HLA-DQ6(1), and HLA-DQ7(3). The patient died because of the disease.- - - - - - - - - - ranking = 4keywords = gynecologic (Clic here for more details about this article) |
9/26. Malignant mixed mullerian tumor of primary mesenteric origin.Malignant mixed mullerian tumor (MMMT) is a rare tumor. A literature search revealed very few reports on MMMT, especially those arising in the peritoneum. We recently encountered an MMMT of primary mesenteric origin associated with left fallopian tube cancer. There have been no previous reports about its occurrence in the mesentery. When cases of peritoneal MMMT were reviewed, the disease was found to be associated with synchronous or metachronous gynecologic tumors of mullerian duct origin (ie, ovarian tumors, primary serous carcinoma of the peritoneum, fallopian tube cancer, endometrial cancer, and adenocarcinoma of the cervix) in 12 out of 32 patients (37.5%). Peritoneal MMMT are frequently associated with gynecologic tumors.- - - - - - - - - - ranking = 2keywords = gynecologic (Clic here for more details about this article) |
10/26. Gynecological malignancies, brain tumors, and familial adenomatous polyposis.The syndrome of familial adenomatous polyposis has a wide spectrum of clinical manifestations including adenomatous polyps of the colon and small bowel, adenocarcinoma of ampulla of vater, tumors of the central nervous system, bone lesions, and various soft tissue tumors. The one common denominator is colonic polyposis. It is not known whether this phenotypic heterogeneity is due to various genotypes, or if the entire clinical spectrum is due to one genetic defect. We are reporting the association of gynecologic malignancies with familial adenomatous polyposis as an additional variant of this disease. This report is on two sisters from a family with familial polyposis coli who developed adenomatous polyposis of the colon, central nervous system tumors, and cancers of the ovary and uterus. The gynecological malignancies add another variant to this clinical syndrome.- - - - - - - - - - ranking = 2keywords = gynecologic (Clic here for more details about this article) |
