1/52. indocyanine green iris angiography of lung carcinoma metastatic to the iris.BACKGROUND: To investigate the usefulness of indocyanine green (ICG) iris angiography for monitoring vascular abnormalities and the clinical course of metastatic iris tumor during chemotherapy. methods: We performed ICG iris angiography at several points during systemic chemotherapy for a 67-year-old man who had been diagnosed as having small-cell carcinoma of the lung with metastatic iris tumors. RESULTS: ICG iris angiography clearly demonstrated hyperfluorescent tumor vessels, rubeosis iridis, and dilated iris stromal vessels. After chemotherapy, these hyperfluorescent vessels and rubeosis regressed. CONCLUSION: ICG iris angiography appears to be an effective and useful method for observing abnormal vessels associated with metastatic iris tumors.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/52. Anesthetic management of high-risk cardiac patients undergoing noncardiac surgery under the support of intraaortic balloon pump.patients with severely impaired left ventricular function, an uncorrectable coronary artery disease, and a recent myocardial infarction are at high risk of cardiac complications after major noncardiac surgery. We present two patients with extensive three-vessel coronary artery disease who underwent intraperitoneal surgery under the support of intraaortic balloon pump (IABP). In one patient, the IABP was inserted urgently because of the development of chest pain with significant ST depression on arrival in the operating room, and the other patient was managed with prophylactic IABP. There were no intraoperative or postoperative cardiac events in either patient. Thus, IABP should be considered in the perioperative management of patients with severe cardiac diseases.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
3/52. ear helix flap for reconstruction of total loss of the upper eyelid.We present a patient with a recurrent carcinoma of the right upper eyelid who underwent resection of the subtotal upper eyelid resulting in a full-thickness defect. The eyelid was reconstructed with advanced conjunctival lining and an ascending helix chondrocutaneous flap from the right auricle. This flap was nourished with a reverse flow of the frontal branch of the superficial temporal vessels. A superficial temporal vein of the flap was anastomosed to the zygomaticofacial branch of the superficial temporal vein at the lateral canthal region to ensure adequate drainage. The flap survived without any congestion. An ascending helix flap is the best candidate for total loss of the upper eyelid.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
4/52. Spindle cell carcinoma of the pancreas.We experienced a rare case of spindle cell carcinoma of the pancreas. The patient was a 74-year-old man who complained of abdominal pain and loss of weight. Ultrasonographic scans revealed a hypoechoic solid mass in the head of the pancreas, 4 cm in diameter, with a high echoic spot suggestive of central necrosis or hemorrhage. The mass was hypodense on enhanced computed tomographic scans and hypovascular on angiograms. At laparotomy, the tumor had invaded to the mesocolon, but dissemination and distant metastasis were not found. We therefore performed pylorus-preserving pancreatoduodenectomy and ascending colectomy. The patient was discharged on postoperative day 26 after an uneventful recovery. Two months later, he was readmitted because of ascites, with positivity of spindle cells shown on cytology; he died on day 92 after surgery. In the resected specimen, the tumor had a mostly sarcomatous component, consisting of spindle-shaped cells, and a small glandular component. Immunohistochemically, both components were positive for cytokeratin and epithelial membrane antigen, but negative for vimentin and desmin. The tumor was diagnosed as a spindle cell carcinoma of the pancreas. Perineural invasion, lymphatic permeation, and blood vessel invasion were found, but lymph node metastasis was not found. Although a curative operation was performed, the outcome in this patient was very poor.- - - - - - - - - - ranking = 1.8089669315995keywords = blood vessel, vessel (Clic here for more details about this article) |
5/52. Leiomyosarcomas of great vessels.Sarcomas of the great vessels are rare. Altogether 400 such cases have been described in the aorta, the pulmonary artery, and inferior vena cava. The clinical symptoms are generally related to embolic phenomena, aneurysm formation, and widespread metastases, especially to bones. With improved diagnostic modalities more cases are diagnosed and treated surgically. Resection of the tumor may prolong the patient s life. In this paper authors present two cases of such rare sarcomas. In our first case a tumor has developed in the thoracic aorta with symptoms of imminent aortic dissection. The tumorous nature of the lesion was revealed only histologically, since neither the operation, nor macroscopic picture gave any clue to its tumorous nature. The second case was a male patient with a huge retroperitoneal tumor arising from the inferior vena cava, which was clinically suspected to be a carcinomaarising in the adrenal gland.- - - - - - - - - - ranking = 1.25keywords = vessel (Clic here for more details about this article) |
6/52. Anaplastic thyroid carcinoma in a 49 year-old woman with a long-standing goiter. A case report.A 49 year-old woman with anaplastic thyroid carcinoma came, for the first time, to our clinic with an enlarged supraclavicular lymph node. Ten years earlier she received a diagnosis of benign nodular goiter and has been followed up with ultrasonography, which never demonstrated any enlargement of her thyroid nodule and with fine needle aspiration biopsies (FNAB), that always proved normal. An ultrasonographic control, performed 10 months before diagnosis, showed the onset of a shell calcification all around the thyroid nodule that forbade the performance of FNAB. At initial examination in our endocrinology centre she was found to have an enlarged thyroid nodule (changing from 3.5 cm to 4.5 cm) and a supraclavicular lymph node 3 cm wide. The patient was therefore sent to the surgeon who performed a total thyroidectomy and a lymph node exenteration. The histological examination reported a thyroid anaplastic carcinoma, composed of osteoclast-like cells and large calcifications, which showed signs of local invasion and vessel infiltration; the supraclavicular lymph node proved to be a large metastasis of anaplastic thyroid cancer. Total body CT scan, bone scintigraphy and brain CT scan showed, respectively, lung, bone and brain metastasis. Postoperative chemotherapy was rapidly interrupted for acute toxicity. The patient died for lung, bone and brain metastasis, 2 months after initial examination.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
7/52. Highly aggressive extraocular sebaceous carcinoma.Extraocular sebaceous carcinoma is an uncommon neoplasm usually localized on the head and neck. We report a case of sebaceous carcinoma of the axillary skin with a highly aggressive behavior. The patient was a 43-year-old black man who developed multiple cutaneous and lymph node metastases shortly after the excision of primary sebaceous carcinoma of the axillary skin. Many neoplastic aggregations were identified within the lumina of the dermal lymphatic vessels in the excised specimen of the primary neoplasm. Although extraocular sebaceous carcinoma has been traditionally considered a less aggressive neoplasm than its ocular counterpart, a review of the literature and this case demonstrate that extraocular sebaceous carcinoma may also lead to disseminated metastatic disease.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
8/52. Selective adrenal venography in an infant with virilizing adrenal cortical carcinoma.Selective adrenal venography in a 10 month old infant with adrenal cortical carcinoma and virilizing symptoms demonstrated grossly dilated, irregular tumor veins. This was an unexpected finding as at aortography no adrenal arteries which would allow selective catheterization, and only very small neoplastic vessels were seen.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
9/52. angiomyolipoma of the bladder.angiomyolipoma of the bladder is an extremely rare neoplasm. We report a case of a 55-year-old woman with an angiomyolipoma of the bladder visualized on pelvic sonogram as a 5 mm polyp in the floor of the bladder. The lesional tissue consisted of spindle cells, epithelioid cells, and adipocytes, with occasional thick-walled blood vessels. Immunohistochemical studies showed the spindle and epithelioid cells to be focally positive for HMB-45 and diffusely positive for actin and muscle cell antigen (HHF-35), which confirmed the diagnosis of angiomyolipoma. A review of the recent literature on the pathogenesis of angiomyolipoma follows.- - - - - - - - - - ranking = 1.8089669315995keywords = blood vessel, vessel (Clic here for more details about this article) |
10/52. Inflammatory fibroid polyp of the ileum causing intussusception: report of two cases with emphasis on cytologic diagnosis.Inflammatory fibroid polyp (IFP) of the gastrointestinal tract is a type of inflammatory pseudotumor or inflammatory myofibroblastic tumor that occurs most commonly in the stomach but also in the small and large bowel. Small-bowel IFP usually presents with intussusception. The purpose of the current study is to describe cytological features of this lesion with differential diagnoses since pathologists may be called on to render a diagnosis on fine-needle aspiration. Two cases of IFP are described with diagnostic features on imprint smears. Both were middle-aged obese women with a history of prior intra-abdominal surgical procedures who presented with signs of intestinal obstruction and were found to have a tumor causing intussusception. At intraoperative consult, scrape cytology specimens showed cellular smears with a heterogeneous population of myofibroblasts, inflammatory cells and vessels. The features together with clinical history are sufficient to suggest the diagnosis. IFP is a lesion with a characteristic morphology. The differential diagnosis includes several other lesions, hence triage of cytological specimen for culture, electron microscopy, and immunohistochemistry is important in facilitating a correct diagnosis. Although a surgical procedure may still be necessary once a diagnosis of IFP is made, treatment may be tailored for a less aggressive process.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
