1/1868. Solitary hepatic hemangioma in a newborn infant complicated by cardiac failure, consumption coagulopathy, microangiopathic hemolytic anemia, and obstructive jaundice. Case report and review of the literature.A newborn infant with a large hepatic hemangioma developed congestive heart failure, consumption coagulopathy, microangiopathic hemolytic anemia, and obstructive jaundice. The patient was mildly heparinized (250 units per kg and day) and underwent successful resection of the tumor without lobectomy at the age of 3 days. blood volume increased from 93.9 ml/kg at the age of 5 h to 124.2 ml/kg prior to surgery. Red-cell mass simultaneously decreased from 53.8 to 39.4 ml/kg. The increase of blood volume is explained by congestive heart failure, the decrease of red-cell mass by intravascular coagulation within the tumor resulting in formation of thrombi and microangiopathic hemolytic anemia. A review of the literature on infants with symptoms caused by an intrahepatic hemangioma during the first month of life confirms that surgical intervention is the treatment of choice for infants with giant solitary hemangioma of the liver.- - - - - - - - - - ranking = 1keywords = hemangioma, angioma (Clic here for more details about this article) |
2/1868. Phakomatosis pigmentovascularis: A new case with renal angiomas and some considerations about the classification.We report phakomatosis pigmentovascularis detected in a Caucasian child characterized by the presence of a nevus flammeus and nevus anemicus on the face, a telangiectatic linear nevus of the right leg, and a very extensive blue spot covering 60% of the body surface, with ocular melanosis. Multiple angiomatous lesions of the kidney are associated without alterations of the central nervous system (CNS). This association has not been reported before; it could be a further expression of the complex of developmental defects. Our case corresponds exactly to type IIb in the classification of phakomatosis pigmentovascularis proposed by Hasegawa. As this classification seems very extensive, the higher incidence of cases corresponding to the second subtype suggests that we should identify it by the term phakomatosis pigmentovascularis, while the others could be considered as only very uncommon variants.- - - - - - - - - - ranking = 0.012637383284975keywords = angioma (Clic here for more details about this article) |
3/1868. The rebound effect in the treatment of complex hemangioma with interferon alpha 2A.The authors report the case of an infant with an extensive face hemangioma with subglottic airway obstruction which had been successfully treated with interferon alpha 2A but then reoccurred with the same dimensions and airway blockage after treatment was abruptly interrupted. The authors suggest the implementation of a standard procedure for the interruption of interferon alpha 2A treatment in order to avoid this rebound effect and advise on the need for further studies to properly evaluate dosage and administration parameters for interferon alpha 2A in the treatment of difficult hemangioma.- - - - - - - - - - ranking = 0.85714285714286keywords = hemangioma, angioma (Clic here for more details about this article) |
4/1868. Localized soft tissue angiomatosis with subsequent development of angiolymphoid hyperplasia with eosinophilia.We report an unusual case of arteriovenous (AV) malformation (localized form of soft tissue angiomatosis): a reaction of angiolymphoid hyperplasia with eosinophilia (ALHE) developed over the lesion of this pre-existing AV malformation. To the best of our knowledge, there is no other report of ALHE in association with a pre-existing bona fide AV malformation. A 71-year-old woman consulted our clinic because a reddish, dome-shaped tumor on her preauricular region, present as a slightly elevated, skin-colored tumor since her childhood, had rapidly enlarged and become more elevated with color change during the preceding two months. The histological features of most of the lesion corresponded to those of soft tissue angiomatosis (localized form). The proliferative vessels underlying the soft tissue angiomatosis streamed out and welled into the dermis with an accompanying prominent inflammatory infiltrate composed of lymphoid cells and eosinophils: these histological features were characteristic of ALHE. The recent abrupt clinical changes in the tumor were considered to represent a reaction to the angiomatosis with development of ALHE.- - - - - - - - - - ranking = 0.02021981325596keywords = angioma (Clic here for more details about this article) |
5/1868. Successful treatment of obstructive sleep apnea with use of nasal continuous positive airway pressure in three patients with mucosal hemangiomas of the oral cavity.cysts and benign tumors are uncommon causes of obstructive sleep apnea (OSA), and surgical removal is usually favored. In patients in whom an operation poses a high risk, however, nasal continuous positive airway pressure (CPAP) may prove beneficial. We describe three patients with hemangiomas of the oral cavity in whom polysomnography revealed moderate to severe OSA. In all three patients, nasal CPAP effectively decreased sleep-related disordered breathing events and dramatically improved their sleep. To our knowledge, this is the first report of OSA associated with hemangiomas involving the upper airway. Our experience suggests that nasal CPAP therapy is effective and well tolerated in such patients.- - - - - - - - - - ranking = 0.85714285714286keywords = hemangioma, angioma (Clic here for more details about this article) |
6/1868. Focal aneurysmal dilatation of subchorionic vessels simulating chorioangioma.Subchorionic vascular aneurysms of the placenta are rare lesions and may present confusion with chorioangioma or focal mesenchymal dysplasia on sonography. To our knowledge, the findings of placental aneurysms have not been reported in the ultrasound literature. We present a case with detailed sonographic evaluation, including spectral and color Doppler and pathological analysis, that was mistaken for chorioangioma prenatally. knowledge of this benign entity may allow the sonologist to recommend conservative management in similar cases.- - - - - - - - - - ranking = 0.01516485994197keywords = angioma (Clic here for more details about this article) |
7/1868. Diffuse neonatal haemangiomatosis: new views on diagnostic criteria and prognosis.Diffuse neonatal haemangiomatosis (DNH) is a rare and life-threatening congenital disorder. An extensive retrospective analysis of the literature was performed to evaluate the clinical features, therapies and prognostic factors of DNH. Reports on 68 patients with DNH were obtained. The skin, liver, lungs, brain and intestine were the organs most commonly involved. Congestive heart failure (CHF) was the primary cause of death. The mortality rate was 77.4% in untreated patients and 27% in treated patients. CHF, kasabach-merritt syndrome (KMS) and the involvement of five or more organs were important risk factors in DNH. The measurement of cardiac output might give more insight into the potential prognostic value of total blood-volume loss through shunting in the haemangiomas. Reports on 64 patients with neonatal haemangiomatosis limited to only the skin and liver were also obtained. The clinical features and outcome of patients with only cutaneous and hepatic haemangiomas were similar to those of patients with DNH. The inclusion criteria for DNH should be expanded to include similar patients with only cutaneous and hepatic haemangiomas.- - - - - - - - - - ranking = 0.022747289912955keywords = angioma (Clic here for more details about this article) |

9/1868. Complex right hemisphere developmental venous anomaly associated with multiple facial hemangiomas. Case report.Complex developmental venous anomalies (DVAs) represent variations of normal cerebral venous drainage and consist of dilation of the superficial and/or deep venous system. These rare anomalies can occur unilaterally or bilaterally, supratentorially or infratentorially, focally or they can affect the entire hemisphere. Some DVAs are associated with cervicofacial venous malformations or facial lymphatic malformations. Anomalies of this type are generally clinically silent, and cerebral dysfunction is usually absent. Symptoms, when they occur, are most commonly headache or mild seizure disorders. The angiographic findings are striking, with well-formed but enlarged transcerebral medullary and deep and/or superficial cortical veins. Opacification of these venous structures occurs within the same time frame as a normal angiographic venous phase. The authors report the case of a 33-year-old man in whom a large inoperable arteriovenous malformation had been previously diagnosed and who presented with seizures. Repeated magnetic resonance imaging and angiography demonstrated abnormally dilated transcerebral, superficial, and deep venous structures involving the entire right hemisphere with no identifiable nidus. Additionally, multiple bilateral benign facial hemangiomas were present in this patient. It is important to recognize this rare venous appearance as a developmental variant and not mistake it for an arteriovenous malformation or a partially thrombosed vein of Galen malformation. Because these venous anomalies are extreme variants of the normal venous system, hemorrhage rarely, if ever, occurs and the patient can be reassured that no interventional or surgical therapy is necessary or warranted.- - - - - - - - - - ranking = 0.71428571428571keywords = hemangioma, angioma (Clic here for more details about this article) |
10/1868.
