1/71. Primary endometrioid carcinoma of fallopian tube. Clinicomorphologic study.Twenty cases of primary Fallopian tube endometrioid carcinoma (PFTEC) are presented in the paper. This accounts for 42.5% of all histologic forms of primary Fallopian tube carcinoma (PFTC) found in our Department. The youngest patient was 38, and the oldest 68 years (mean: 56 years). Seven patients were nulliparas. Only two cases were bilateral. According to FIGO staging, 13 cases were evaluated as stage I, 4 as II, and 3 as stage III. Due to the histologic grading, 8 tumors were classified as well, 7 as moderately, and 5 as poorly differentiated. In the time of preparation of the manuscript, 12 women were still alive, 2 of them with recurrent disease. The follow-up of patients without recurrence ranged from 4 to 120 months (median: 63). Eight patients had died (survival time: from 4 to 65 months; median: 26). Metastases were found in 8 patients, especially to ovaries. In 14/20 cases of PFTEC various forms of tubal wall invasion were observed. Blood or lymphatic vessels involvement was found in 9 patients. Six of them had died and one is alive with the symptoms of disease. Immunohistochemical detection of the mutant form of p53 protein and oncogene product, c-erbB-2, was studied in 17 cases. Nine patients exhibited simultaneous p53 protein accumulation and c-erbB-2 expression. 2/9 of these patients are alive with recurrent tumors and 4/9 died. Endometrioid carcinoma of the Fallopian tube can be characterized by a tendency to superficial invasion of tubal wall and in a half of the cases by invasion of vessels. The majority of these tumors were diagnosed at an early stage tumors.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/71. Multiple piloleiomyomas associated with solitary angioleiomyoma.A 58 year-old male had reddish scattered papules strictly confined to the right side of his upper back and neck, right shoulder, and right upper arm. Additionally, he also noticed a subcutaneous nodule on his left thigh. Histopathological examinations revealed that the papules on the back, nape of the neck, shoulder, and arm were multiple piloleiomyomas, as shown by the proliferation of bundles of smooth muscles in the dermis. The subcutaneous nodule of the thigh was angioleiomyoma with a well-circumscribed lesion composed of smooth muscles and blood vessels. Ipsilaterality and segmentality of the distribution of the papules of piloleiomyomas and probable family history that his mother had similar papules with a similar distribution suggest the nevoid character of our case. Piloleiomyomas are often reported to be associated with leiomyoma of the uterus or other organs. This is the first reported case of multiple piloleiomyomas with solitary angioleiomyoma in the literature.- - - - - - - - - - ranking = 5.1657531067309keywords = blood vessel, vessel (Clic here for more details about this article) |
3/71. Lymphangiectasia within angiomyolipoma in a tuberous sclerosis patient.This is a presentation of a case of tuberous sclerosis with multifocal hamartomas in the retroperitoneum, both kidneys, and the liver. Lymphangiectasia and numerous ectatic lymphatic channels penetrating through the retroperitoneal angiomyolipoma were demonstrated by lymphography and computed tomography. The findings in our study may document the presence of degenerative change in the lymphatic system--not just in elastic vessels--an association which has not yet been reported in the radiological literature.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
4/71. Synchronous carcinoma of the gallbladder in a patient with intrahepatic bile duct carcinoma.An 83-year-old woman, diagnosed as having cholelithiasis, was admitted to the Department of Surgery, Nippon Medical School, with right hypochondrial pain. ultrasonography and computed tomography revealed a mass in the gallbladder fundus and a hypovascular tumor in the anterior segment of the liver. magnetic resonance imaging showed stenosis of the intrahepatic bile duct and dilatation of its proximal portion. She was diagnosed as having intrahepatic bile duct carcinoma combined with gallbladder carcinoma. At laparotomy, there was evidence of multiple peritoneal metastases and intraoperative histological examination of the gallbladder tumor revealed adenocarcinoma. Accordingly, only cholecystectomy and needle biopsy of the liver tumor was performed. Histological examination of the gallbladder revealed papillary adenocarcinoma invading the muscularis propria with medullary growth or intermediate stroma. There was no microvessel invasion, no perineural invasion and no lymph node involvement. On the other hand, the liver tumor was a cholangiocarcinoma with a well-differentiated tubular pattern. Therefore, this was a rare case of synchronous carcinoma of the gallbladder associated with intrahepatic bile duct carcinoma.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
5/71. Localized multiple glomus tumors of the face and oral mucosa.We describe a 54-year-old patient with an unusual localization of localized multiple glomus tumors. She had several nodules on the left mandibular area, lower lip, and anterior part of the buccal mucosa. A biopsy taken from the left mandibular area showed cystically dilated vessels lined by endothelial cells and a few outer layers of glomus cells in the dermis to subcutis. Localized multiple glomus tumors are rare, and both their facial and oral mucocal localization are extremely rare.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
6/71. Primary bilateral mucosa-associated lymphoid tissue lymphoma of the breast with atypical ductal hyperplasia and localized amyloidosis. A case report and review of the literature.Primary non-Hodgkin lymphoma of the breast is a rare disease. Primary mucosa-associated lymphoid tissue lymphoma is even rarer, and bilateral involvement is exceptional. We describe a case of primary bilateral breast mucosa-associated lymphoid tissue lymphoma with bilateral atypical ductal hyperplasia and bilateral localized amyloidosis in a 64-year-old woman with a history of arthritis and systemic lupus erythematosus and its clinical, histologic, and immunohistochemical features. Microscopic examination of the breast lesion showed dense periductal and perilobular small and plasmacytoid lymphocytes with eosinophilic amyloid in the vessels and the stroma. Bilateral single foci of atypical ductal hyperplasia were also noted. Fine needle aspiration showed small and large lymphocytes and plasma cells. Molecular analysis demonstrated a heavy chain immunoglobulin H gene rearrangement. flow cytometry studies showed an abnormal B-cell population. The combined histologic, paraffin immunohistochemistry, flow cytometry, and molecular results were considered diagnostic for low-grade mucosa-associated lymphoid tissue lymphoma. The patient underwent bilateral local breast radiation without other organ or site involvement.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
7/71. Multiple hemangiomas of the foot: a case report.Although hemangiomas are common soft tissue tumors, it rarely involves the feet. We are reporting a forty-seven-year-old female with multiple hemangiomas of her left foot without pain. During surgery there were seven well-defined masses that were totally excised after ligation of penetrating vessels. The microscopic investigation revealed mixed-type (capillary and cavernous) hemangioma. We had not experienced any recurrence after two years follow up period.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
8/71. Localized birt-hogg-dube syndrome with prominent perivascular fibromas.The autosomal dominant birt-hogg-dube syndrome is a cutaneo-intestinal condition that manifests on the skin in the form of multiple, skin-colored small papules that, histologically, prove to be mantleomas (fibrofolliculomas and trichodiscomas). These cutaneous lesions usually appear in the region of the head, neck, and upper part of the trunk. To date, only a single report in the literature describes the localized occurrence of this syndrome. We now describe a localized form of the birt-hogg-dube syndrome in a man with multiple mantleomas that were confined to the left half of the face, and which, in part, were arranged in the form of plaques. Another striking finding in this patient was a conspicuous vascular component in the lesions, characterized by a pronounced, well-demarcated fibrosis in the region of cutaneous blood vessel proliferations. Because perivascular fibromas have already been observed in other patients with Birt-Hogg-Dube-syndrome, the perivascular fibroma, with fibrofolliculoma and trichodiscoma, must be included within this syndrome's spectrum of skin changes.- - - - - - - - - - ranking = 5.1657531067309keywords = blood vessel, vessel (Clic here for more details about this article) |
9/71. Aortico-pulmonary paraganglioma associated with bilateral carotid body tumors. Diagnostic presentation and clinical implications.A case of mediastinal paraganglioma in association with bilateral carotid body tumors is presented. Characteristic radiological findings included a hypointense signal in T1-weighted, a hyperintense signal in T2-weighted magnetic resonance (MR) images and a vascular enhancement pattern in dynamic contrast enhanced MR imaging. Thus, feeding vessels could be depicted noninvasively. The importance of family screening in affected individuals is stressed, as a hereditary form of the disease exists in which multiple paragangliomas are common.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
10/71. calciphylaxis associated with cholangiocarcinoma treated with low-molecular-weight heparin and vitamin K.calciphylaxis is a rare disorder of small-vessel calcification and cutaneous infarction associated with chronic renal failure. Rare cases of calciphylaxis not associated with chronic renal failure have been reported with breast cancer, hyperparathyroidism, and alcoholic cirrhosis. To our knowledge, we report the first case of calciphylaxis without chronic renal failure associated with cholangiocarcinoma and the first attempt to treat calciphylaxis with vitamin K. A 56-year-old woman presented with necrotic leg ulceration. She was treated initially with low-molecular-weight heparin, with no effect. A coagulation work-up showed vitamin k deficiency. During vitamin K therapy, the patient had fulminant progression of the calciphylaxis. She died, and an autopsy showed metastatic cholangiocarcinoma. thrombosis and protein c deficiency have been implicated in the pathophysiology of calciphylaxis. Functional protein c deficiency may be one of several factors contributing to the development of calciphylaxis. Vitamin K therapy was ineffective in our patient and may have been detrimental.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
