1/41. Lymphocutaneous fistula as a long-term complication of multiple central venous catheter placement.We report a case of a lymphocutaneous fistula in a 19-month-old boy who had been a premature neonate, born in the 23rd week of gestation. The fistula, an apparent complication of central venous line placement during the patient's first 5 months of life, was composed of a distinct lymphatic vessel bundle in the right supraclavicular region, with its exit point at the posterior aspect of the right shoulder. The drainage ceased immediately after resection and repair of a 1-cm obstruction in the superior vena cava.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/41. The use of subatmospheric pressure dressing therapy to close lymphocutaneous fistulas of the groin.groin lymphorrhea is an uncommon but serious complication of vascular and cardiac surgery as well as interventional procedures that cannulate the femoral vessels. Treatment options are somewhat controversial. For lymphocutaneous fistulas, a commonly used current modality is early surgical ligation with the assistance of blue-dye staining of the lymphatic anatomy. The purpose of this case series is to give the first description of a new, less invasive, approach using subatmospheric pressure dressing therapy for the treatment of the challenging problem of lymphocutaneous fistulas of the groin.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/41. Angiomyomatous hamartoma and associated stromal lesions in the right inguinal lymph node: a case report.Angiomyomatous hamartoma is a rare disease with a predisposition for the inguinal lymph nodes. A 51-year-old male patient visited a local hospital because of a right inguinal mass, measuring 3 x 4 cm in size, which was resected. The resected specimen showed irregularly distributed thick-walled vessels in the hilum, extending into the medulla and focally into the cortex of the node, eventually becoming more dispersed and associated with smooth muscle cells splaying into sclerotic stroma. These findings are compatible with an angiomyomatous hamartoma. Another tumor-like mass appeared shortly after the resection at the same location, but was not an angiomyomatous hamartoma, rather it was composed of edematous stromal tissue with proliferating smooth muscle cells. The stromal component included thick-walled blood vessels and lymphatics. Although it could not be determined whether these associated changes in the surrounding stroma are a cause or an effect of angiomyomatous hamartoma, they indicate the clinical difficulty in determining an appropriate area of resection and may provide clues to the pathogenesis of angiomyomatous hamartoma.- - - - - - - - - - ranking = 6.3409681078539keywords = blood vessel, vessel (Clic here for more details about this article) |
4/41. Hereditary haemorrhagic telangiectasia simulating biliary tree obstruction secondary to malignant porta hepatis lymphadenopathy.Hereditary telangiectasis is an uncommon condition and is thus not usually considered in the differential diagnosis of porta hepatis lymphadenopathy causing biliary tree obstruction. The present case illustrates a patient in whom tortuous vessels in the porta hepatis simulated masses on delayed contrast-enhanced CT with subsequent referral for biopsy.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/41. Postmenarchal development of chylous ascites in acrocephalosyndactyly with congenital lymphatic dysplasia.BACKGROUND: Acrocephalosyndactyly is a syndrome characterized by congenital malformation of the skull with craniosynostosis, midface hypoplasia, and symmetrical webbed fusion of the fingers and toes. We describe a possible pathophysiologic mechanism for chylous ascites that developed several months after menarche in a woman with acrocephalosyndactyly and congenital lymphatic dysplasia. CASE: A 25-year-old nulligravid woman with acrocephalosyndactyly, at 18 months after menarche, developed persistent abdominal distension at age 18 years. laparoscopy at age 25 years revealed chylous ascites with marked chronic peritoneal inflammation, and lymphatic dysplasia with lymphocysts. With hormone manipulation, the chylous ascites fluctuated. CONCLUSION: After menarche in a woman with acrocephalosyndactyly, ovarian steroid hormones might have increased lymph production and hydrostatic pressure, causing rupture of congenitally dysplastic lymph vessels resulting in chylous ascites.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/41. thoracic duct cyst presenting as an hour-glass shaped mass in the left supraclavicular area: case report.thoracic duct cyst presenting as an hour-glass shaped mass in the left supraclavicular area: case report. thoracic duct cysts are a very rare entity in the head and neck pathology. We present a case of a 52 year-old man, who was referred to our service, complaining by a 30 days left cervical mass, with no other symptoms. A 6 cm cystic mass was revealed after ultrasonography and CT. Needle aspiration confirmed the presence of lymph in the cyst. The treatment was simple excision. Special care was taken to ligate the connected lymphatic vessels.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/41. Subcutaneous angiolymphoid hyperplasia (Kimura disease). Report of a case.A subcutaneous mass removed from the cheek showed histologic features of subcutaneous angiolymphoid hyperplasia (Kimura disease) at its early stage. The condition shows a wide spectrum of pathologic changes. At its early stage, the main findings consist of active vascular proliferation with plump endothelial cells and varying degrees of lymphocytic, histiocytic, and eosinophilic infiltration. The lesion at its later stage features hyperplastic blood vessels with inconspicuous endothelial cells, well-formed lymphoid follicles, and varying degrees of lymphocytic and eosinophilic infilitration. Blood eosinophilia is frequently seen. review of the literature and study of our own case strongly suggest that this disease is a distinct clinical and pathologic entity.- - - - - - - - - - ranking = 5.3409681078539keywords = blood vessel, vessel (Clic here for more details about this article) |
8/41. An autopsy case of intravascular lymphomatosis with dermatomyositis.A 62-year-old man was admitted to hospital with general malaise, arthralgia, edema, and high-grade fever. He was diagnosed as dermatomyositis because of typical skin rashes and muscle weakness. His symptoms were improved by high-doses of prednisolone and cyclosporin A, with the exception of the skin rash over the back. High-grade fever developed again when tapering prednisolone. His condition deteriorated gradually. paresthesia, hypothyroidism, metabolic acidosis, and disseminated intravascular coagulopathy occurred, and he died eight months after the first admission. Postmortem examination revealed intravascular proliferation of atypical mononuclear cells in the lumens of small vessels in all organs. Intravascular lymphomatosis (B cell type) was diagnosed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/41. REM syndrome (reticular erythematous mucinosis): report of a further case or variant of it.A 50-year-old woman had cervical lymphadenopathy, swollen and waxy-looking gums, and a diamond-shaped, reticular erythematous eruption on her back of eight years' duration. Histologic examination of the gingival tissue and skin showed round-cell infiltration around the small blood vessels and in the upper part of the dermis, and an extensive eosinophilic amorphous deposit throughout the dermis that stained with alcian blue. The clinical and histologic features, although not identical, resembled those reported by Lischka and Orthenberger (1972) and later by Steigleder et al (1974).- - - - - - - - - - ranking = 5.3409681078539keywords = blood vessel, vessel (Clic here for more details about this article) |
10/41. F-18 fluorodeoxyglucose uptake in atherosclerotic plaque in the mediastinum mimicking malignancy: another potential for error.atherosclerosis is an inflammatory process accumulating numerous inflammatory cells such as macrophages and lymphocytes. This cellular infiltrate has a high metabolic demand, which can be reflected on F-18 FDG positron emission tomographic (PET) imaging. The FDG uptake in atherosclerotic vessels is usually distinguishable as a result of its linear and continuous appearance and mild level of activity. However, occasionally, atherosclerotic plaques present themselves as focal "hot spots," which can be easily misinterpreted as malignancy. This report emphasizes atherosclerotic plaques as a potential pitfall while interpreting FDG scans. It also highlights the importance of radiographic correlation to avoid such an error.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
