1/23. Mixed malignant germ cell tumor of the fallopian tube.Immature teratomas of the fallopian tube are exceedingly rare with only three reported cases in the English literature. Reported here is a case of primary mixed malignant germ cell tumor of the fallopian tube composed of immature teratoma and yolk sac tumor.- - - - - - - - - - ranking = 1keywords = fallopian tube, tube (Clic here for more details about this article) |
2/23. Malignant mixed Mullerian tumor of the fallopian tube: report of two cases and review of literature.Malignant mixed Mullerian tumors are usually found in the endometrium, vagina, cervix, and ovary. It is extremely rare for this tumor to arise in the fallopian tube, and to date only 37 tubal cases have been reported. We recently experienced 2 such cases. The clinical features, pathologic findings, diagnosis, therapy, and outcome of these 39 cases were reviewed. The clinical features and diagnosis were similar to those of primary carcinoma of the fallopian tube. Correct preoperative diagnosis was difficult. Histologically, 18 patients had homologous elements and 21 had heterologous elements in the sarcomatous components. The most common type of heterologous element was cartilage, followed by striated muscle and bone. The clinical stage (FIGO staging of ovarian carcinoma) was stage I in 15 cases, stage II in 11 cases, stage III in 8 cases, stage IV in 3 cases, and unknown in 2 cases. In all the patients except 1, the tumor was surgically removed. Postoperatively, radiotherapy was given to 9 patients, chemotherapy to 9 patients, and both to 2 patients. Sixteen patients died of the disease, after a mean period of 16.1 months. Of the 15 stage I patients, 10 survived more than 12 months. The most important prognostic factor was spread of the tumor at diagnosis.- - - - - - - - - - ranking = 0.83403251335181keywords = fallopian tube, tube (Clic here for more details about this article) |
3/23. Unusual location of ovarian mixed germ cell tumor.Intra-abdominal unusual location of mixed germ cell tumor of ovary, which consisted of endodermal sinus tumor and immature teratoma components, has been reported. Patient was a 21-year-old girl with a chief complaint of abdominal pain and mass. Ultrasound and computed tomography scan showed lobulated cystic mass. laparotomy was performed, and due to specific localization, in which tumor localized as a tumoral bridge between two ovaries, we just performed maximal fertility-sparing surgery by preserving ovaries, tubes, and uterus. After that, four courses of chemotherapy (bleomycin, etoposide, and cis-platinum) were done to cure her. The alfa-fetoprotein became negative after three courses of chemotherapy, and she is under observation for the time being.- - - - - - - - - - ranking = 0.00069918001847698keywords = tube (Clic here for more details about this article) |
4/23. Malignant mullerian mixed tumor (carcinosarcoma) of the fallopian tube: an immunohistochemical study of neoplastic cells.The patient was a 65-year-old woman who complained of lower abdominal pain. Salpingo-oophorectomy and hysterectomy were performed due to suspicion of ovarian cancer. At surgery a polypoid mass was observed in the fimbria of the left fallopian tube. Histologically, proliferation of undifferentiated neoplastic cells with marked cytological atypia predominated in the tumor. Proliferation of rhabdomyoblastic cells or spindle cells, as well as adenocarcinoma arising from the mucosa of the fallopian tube, was observed. A diagnosis of malignant mullerian mixed tumor (MMMT) was made. CD10 was expressed in adenocarcinoma, undifferentiated, spindle and rhabdomyoblastic cells. Furthermore, rhabdomyoblastic cells were positive for desmin and myoglobin. Undifferentiated and spindle neoplastic cells were focally positive for ASMA and negative for h-caldesmon. Finally, our preliminary report suggests that MMMT of the fallopian tube may contain immature smooth muscle cells or cells with the myofibroblast-like immunohistochemical phenotype in the undifferentiated component.- - - - - - - - - - ranking = 1.0006991800185keywords = fallopian tube, tube (Clic here for more details about this article) |
5/23. Malignant mixed mullerian tumor of the fallopian tube. Case report and review of the literature.Malignant mixed mullerian tumor of the fallopian tube is extremely rare, with less than 50 cases recorded in the English literature. Another case is reported and discussed. This 66-year-old female patient complained of profuse watery vaginal discharge for one month. Vaginal cytology was positive for malignancy while the endometrial curettage and cervical biopsy were both negative. Gynecologic sonography revealed a left adnexal mass of 6 cm in diameter. She underwent exploratory laparotomy after complete oncologic survey. The main tumor was confined to one tube but the peritoneal washing cytology was positive for adenocarcinoma cells. She tolerated the maximal debulking surgery very well but refused to receive adjuvant chemotherapy. pathology proved that the tumor was composed of poorly differentiated adenocarcinoma and sarcoma. There were focal areas of rhabdomyoblastic differentiation with cross striation in immunoperoxidase stain. Carcinomatosis peritonii occurred 12 months after primary surgery and she expired one month later.- - - - - - - - - - ranking = 0.83403251335181keywords = fallopian tube, tube (Clic here for more details about this article) |
6/23. Malignant mixed mullerian tumor of the fallopian tube.Malignant mixed Mullerian tumor (MMMT) of the fallopian tube is an extremely rare neoplasm with a poor prognosis. To date, only 37 cases have been reported. The primary treatment for this tumor is surgery. Chemotherapy has been used with some success. The role of radiotherapy is less clear. A case of malignant mixed Mullerian tumor of the fallopian tube occurring in a 63- year- old woman, presenting with postmenopausal vaginal spotting for 7 months, is reported.- - - - - - - - - - ranking = 1keywords = fallopian tube, tube (Clic here for more details about this article) |
7/23. Simultaneous occurrence of melanotic neuroectodermal tumor and brain heterotopia in the oropharynx.A case is described of heterotopic brain tissue with simultaneous occurrence of melanotic neuroectodermal tumor in the oropharynx of a 6-week-old infant. The melanotic neuroectodermal tumor was embedded within the heterotopic glial tissue. This coexistence leads us to speculate that a defect causing a pinching-off of both neural crest cap and medullary epithelium of neural tube might have taken place at, or before, the 25-30 somite stage. The displaced embryonic structures subsequently differentiated into glial tissue, choroid plexus, and melanotic neuroectodermal tumor. This observation may be interpreted as further support in favor of a neural crest origin of juvenile melanotic neuroectodermal tumor.- - - - - - - - - - ranking = 0.00069918001847698keywords = tube (Clic here for more details about this article) |
8/23. Melanotic neuroectodermal tumors of the brain and skull.A case of melanotic neuroectodermal tumor in the cerebellum of a 21-year-old man is presented. Melanin was found mainly in small neoplastic cells rather than in large epithelioid cells. The tumor also contained neurons, as well as neoplastic tissue of ependyma, choroid plexus; and astrocytes. We propose that this neuroectodermal tumor resulted from a combination of cells originating in the neural crest and in the neural tube. The small cells have been described as medulloblasts, but they may be poorly differentiated ependymal cells, or, sympathicoblasts. The presence of pigment in these cells is compatible with an origin in the neural crest. The so-called melanotic progonoma, occurring most often in the maxilla of infants, is reviewed in relation to the melanotic neuroectodermal tumor of the brain. The tumor in facial bone occurs in adults as well as infants, in locations other than the maxilla, and has malignant forms. Melanotic neuroectodermal tumors, whether in brain or bone, are therefore similar in behavior as well as histologic appearance. The finding of similar tumors in these different locations is readily explained embryologically.- - - - - - - - - - ranking = 0.00069918001847698keywords = tube (Clic here for more details about this article) |
9/23. carcinosarcoma and mixed mullerian tumors of the fallopian tube: report of four cases.We report a 74-year-old woman with malignant mixed mullerian tumor and three women, aged 47, 58, and 76 years, with carcinosarcomas, all primary in the fallopian tube. The tumors grew predominantly intraluminally and were associated with hydrosalpinx. All four patients underwent salpingectomy. Two of them received radiation therapy; one died within 9 months because of the tumor and the second is well 2 years after diagnosis. Of the two women without additional therapy, one is alive with tumor 53 months postoperatively and the other is well 1 year after surgery. Available data suggest that these neoplasms are relatively radioresistant and that their prognosis correlates best with local invasiveness.- - - - - - - - - - ranking = 0.83333333333333keywords = fallopian tube, tube (Clic here for more details about this article) |
