1/57. Giant myoma and erythrocytosis syndrome.The objective of this study is to discuss the myomatous erythrocytosis syndrome in a patient with a giant subserous uterine myoma. She presented with plethora and an abdominal mass. After venesection of 4 units of blood, the preoperative haematocrit value of 53.3% and haemoglobin value of 17.5 g/dL had decreased to 48.6% and 16.8 g/dL levels, respectively. After the operative extraction of the giant subserous myoma with attached uterus weighing 14.2 kg, the haematocrit and the haemoglobin values had regressed to 40.3% and 14.3 g/dL levels, respectively. The findings indicated that the giant subserous myoma was the cause of the myomatous erythrocytosis syndrome in this patient.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/57. Pathologic features of uterine leiomyomas following uterine artery embolization.Bilateral uterine artery embolization has recently been employed as an alternative to operational treatment of uterine leiomyomas. The pathologic features induced by uterine artery embolization have not been previously described in detail. Usually patients experience symptomatic improvement with a reduction in size of the leiomyomas. This report describes the pathologic features in a series of 10 uterine leiomyomas where tissue was available for histologic examination following uterine artery embolization. Characteristic histologic features within the leiomyomas included massive necrosis, sometimes with dystrophic calcification, vascular thrombosis, and intravascular foreign material that elicited a histiocytic and foreign-body giant cell reaction. In some cases, intravascular foreign material was present elsewhere in the myometrium, the cervix, or paraovarian region. In occasional cases, there were foci of myometrial necrosis and microabscess formation beyond the confines of the leiomyomas. Foci of extrauterine inflammation were also occasionally identified. Histopathologists should be aware of these findings because the use of uterine artery embolization will possibly become more widespread in the future.- - - - - - - - - - ranking = 0.33333333333333keywords = giant (Clic here for more details about this article) |
3/57. Malignant fibrous histiocytoma of the uterus.A 56-year-old menopausal woman was admitted to hospital because of vaginal spotting of several months duration. The patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy and omentectomy. On divalving, the uterus showed an ulcerated nodule 8 cm in diameter, protruding into the uterine cavity from the posterior wall. Histologically the tumor had a typical morphology of malignant fibrous histiocytoma (MFH). Multinucleated giant cells were strongly positive for CD 68 alpha antichymotripsin and alpha antitrypsin. Mononuclear cells also showed the same immunohistochemical pattern though less intensive than the giant cells. The cells were uniformly negative for S-100 protein, myoD1, myogenin desmin and actin. Electron microscopical investigation disclosed ultrastructural features compatible with the histiocytic nature of the tumor. Thirty-three months later the patient was free of disease.- - - - - - - - - - ranking = 0.66666666666667keywords = giant (Clic here for more details about this article) |
4/57. Osteoclast-like giant cells in leiomyomatous tumors of the uterus. A case report and review of the literature.Osteoclast-like giant cells (OLGC) in leiomyomatous tumors of the uterus are rarely seen, and their significance is unknown. We present a case of a large leiomyomatous tumor in which OLGC were found in only few sections showing leiomyosarcoma whereas the majority of sections revealed a leiomyoma. Though radically operated, the patient died a few months later with recurrent tumor in the pelvis and metastases to the lungs.- - - - - - - - - - ranking = 1.6666666666667keywords = giant (Clic here for more details about this article) |
5/57. Uterine carcinosarcoma with melanocytic differentiation.A 65-year-old black woman was found to have a 3.0 cm endometrial tumor that was a carcinosarcoma with a major epithelial and a less prominent mesenchymal component. The latter was undifferentiated but one focus of chondroid differentiation was noted. The former showed papillary serous differentiation. Melanin pigment was observed in both epithelial and mesenchymal components. Staining with antisera to S100 protein and HMB-45 confirmed the presence of melanocytes. An endocervical focus of tumor also contained melanin. Electron-microscopic studies showed large tumor cells with an irregularly indented nucleus and abnormal giant cytoplasmic melanosomes. Only one case of uterine carcinosarcoma with melanocytic differentiation has been previously reported.- - - - - - - - - - ranking = 0.33333333333333keywords = giant (Clic here for more details about this article) |
6/57. Cytologic features of a primary myxoid malignant fibrous histiocytoma arising in the uterus: a case report.BACKGROUND: Primary malignant fibrous histiocytoma (MFH) of the uterus is extremely rare. The 10 cases reported in the literature all involved the pleomorphic variant, and to the best of our knowledge, the myxoid variant has not been reported before. We describe the cytologic findings of primary uterine myxoid MFH in relation to the myxoid component, potentially leading to an incorrect diagnosis. CASE: A 68-year-old woman presented with a primary uterine tumor. Endometrial cytology showed numerous loosely arranged, spindle-shaped fibroblastlike cells; atypical histiocytelike cells; and giant cells with a necrotic background. The overall cytologic picture was of a degenerated pleomorphic leiomyosarcoma with an inconclusive diagnosis. A diagnosis of myxoid MFH was established after electron microscopic and immunohistochemical studies of the primary tumor and tumor transplanted, as primary cultured cells, in nude mice. The patient underwent an exploratory laparotomy and died of tumor progression 38 days after the initial consultation, without treatment. CONCLUSION: Because of overlapping cytologic features among uterine sarcomas with myxoid stroma, it is important to recognize the histiocytic lineage of tumor cells by immunohistochemistry and electron microscopy in various presentations of fresh samples.- - - - - - - - - - ranking = 0.33333333333333keywords = giant (Clic here for more details about this article) |
7/57. Epithelioid trophoblastic tumor of the uterus: cytological and immunohistochemical observation of a case.Epithelioid trophoblastic tumor (ETT) is a new entity of trophoblastic tumor and 14 such cases were reported by Shih and Kurman in 1998. However, only three subsequent cases supporting ETT have been reported. Recently, we experienced a case of ETT in a 37-year-old woman whose preoperative endometrial brushings showed atypical mononucleate giant cells and who underwent hysterectomy with the diagnosis of a uterine fibroid. The specimens revealed a 2.5 x 3.0 cm yellow-tan intramural nodule located in the lower uterine segment, which was composed of a neoplastic proliferation of intermediate trophoblasts in epithelioid arrangements. Immunohistochemically, the tumor cells were diffusely positive for cytokeratin and inhibin-alpha, and focally positive for human chorionic gonadotropin and human placental lactogen. She presented an uneventful clinical course as of September 2001.- - - - - - - - - - ranking = 0.33333333333333keywords = giant (Clic here for more details about this article) |
8/57. Giant uterine tumors: two cases with different clinical presentations.BACKGROUND: Giant uterine tumors are uncommon. However, they may be life threatening because of pressure effects on the lungs and other adjacent organs. Proper surgical management and careful perioperative care are essential to assure a good outcome after excision. CASE: Two women with giant uterine leiomyomata (weighing more then 40 kg [88 lb]) are discussed. In one case the leiomyoma led to severe pulmonary hypertension and respiratory failure necessitating an emergency operation. Abdominal hysterectomy and bilateral salpingo-oophorectomy were successfully carried out in both cases, which are among the largest tumors ever removed with survival of the patient. CONCLUSION: Different clinical manifestations can be expected in cases of giant uterine tumors according to which other organs are secondarily affected. Numerous difficulties may be encountered in the evaluation and removal of these tumors. A combined team consisting of gynecologic, general, and plastic surgeons is necessary for a successful outcome.- - - - - - - - - - ranking = 0.66666666666667keywords = giant (Clic here for more details about this article) |
9/57. Diagnostic aspects of hydatidiform mole with persistence of polymorphic trophoblastic hyperplasia.SUMMARY: The persistence of polymorphic trophoblastic hyperplasia in a hydatidiform mole is an extremely rare condition. Its early recognition is essential since such cases can transform into invasive types of tumors. MATERIALS AND methods: The biopsies were routinely processed in paraffin, embedded and stained with HE. Immunohistochemical staining reactions were performed with the following monoclonal antibodies for hydatidiform mole: beta-hCG, HPL, MIB1, CK18, HER-2/neu, p53 and carbohydrate antibodies, Thomsen-Friedenreich antigen, Glycodelin A, Mucl and Mucl-cor. RESULTS: Large villi and hydatidiform villi with wide-ranged syncyctio- and cytotrophoblasts were seen. Intervillous proliferating trophoblasts showed cell- and nuclear polymorphy with a wall invasion of the myometrium. The immunohistochemistry exhibited strong positivity for the membrane-associated HER-2/neu and for the beta-hCG in syncytiotrophoblast and in multinuclear giant cells of intervillus trophoblasts. A weakly positive reaction with hPL was seen in most cells of the trophoblasts. The rest of the immunohistochemistry served as a diagnostic support. CONCLUSION: A complete hydatidiform mole with hyperplasia and proliferation of polymorphic trophoblasts presents a high risk of developing a persistent (eventually metastatic) trophoblastic disorder and, in up to 15% of the cases, an invasive mole. In 2.5% of the cases it can transform into a choriocarcinoma.- - - - - - - - - - ranking = 0.33333333333333keywords = giant (Clic here for more details about this article) |
10/57. Cavernous lymphangioma arising from uterine corpus.BACKGROUND: A rare case of giant uterine lymphangioma was experienced. CASE: A 44-year-old female noted a rapidly grown abdominal tumor and its accompanied symptoms, progressive abdominal distension, lumbago, and developed leg edema. ultrasonography made a possible diagnosis of a huge ovarian tumor; postoperative diagnosis was cavernous lymphangioma arising from the uterus. CONCLUSION: According to the literature, lymphangioma itself is a rare tumor, and giant lymphangioma arising from uterine corpus is extremely rare. We experienced an extremely rare case of uterine lymphangioma and ultrasound tomography better imaged the tumor inside.- - - - - - - - - - ranking = 0.66666666666667keywords = giant (Clic here for more details about this article) |
