[Arteriography of the celiac tripod in lymphomas. Critical evaluation].

The possible contribution of arteriography of the coeliac tripod to lymphoma staging is discussed with special regard to the demonstration of spleen and liver involvement; as regards the former, caution is advised owing to the chance of errors of interpretation; as for the latter, mention is made of the possibility of demonstrating infiltrations of the liver and stenosis of the hepatic artery due to lymphnode involvement that cannot be shown up by laparotomy.

Metastasis-associated cell functions in AKR lymphoma malignancy variants.

Multiple structural and functional cell properties are responsible for the complex phenotype of the metastatic cell. Cells derived from AKR lymphoma malignancy variants were compared with regard to several cellular functions relevant to the metastatic behavior. Metastatic behavior correlated with relevant in vitro cell activities, such as cell motility, homotypic and heterotypic adhesion as well as proteolytic activity. The Variant displaying the highest degree of malignancy, TAU-42, exhibited the most elevated ability to perform almost each of the cell functions examined: motility, aggregability, capacity to adhere to endothelium and extracellular matrix, heparanase and protease activity and ability to grow in the spleen. The TAU-33 variant was second in rank in the performance of the above activities. The TAU-44 variant cells, the third in rank of malignancy, displayed some peculiar functional behavior: while manifesting the lowest homotypic adherence and heparanase activity, they had a high predilection for growth in kidney.

Multifocal malignant hemangioendothelioma presenting as acute hepatitis. A clinicopathologic study.

A patient with malignant hemangioendothelioma of the liver is described. The patient's clinical presentation and course were that of fulminant hepatic necrosis. Complications included upper gastrointestinal hemorrhage, hepatic encephalopathy, abnormal coagulation parameters and the hepatorenal syndrome. The duration of the illness from the onsetof symptoms to its fatal outcome was five weeks.

[Inflammatory pseudotumor of the spleen. An old concept with many questions].

Inflammatory pseudotumor of spleen is an infrequent benign condition. It is difficult to differentiate, on a clinical and radiological basis, from haematologic neoplasms, granulomatous diseases as sarcoidosis and splenic hamartoma. Sometimes can be an incidental finding. Two women, aged 72 years, are presented. On the first case the sympthons mi micked a malignant disease. The second one was an incidental finding in a routine study for cholecystitis. Histological and immunohistochemical study showed a polymorphic cellular population including plasma cell, lymphoid cells, histiocytes, eosinophils and spindle cells, showing a reactive benign character. Plasma cells presented light chains polyclonality. Lymphoid cells were mature and with T inmunophenotype. Spindle cells were focally positive for muscle spe-cific actin and vimentine. In the first case, ultraestructural study showed myofibroblast morphology on the stromal spindle cells. Like many other authors have already postulated, immunohistochemical and ultraestructural findings would corroborate the mesenchymal reactive and benign nature of this type of lesions.

Intrasplenic metastases from carcinoma of the ovary.

Intrasplenic metastases are an uncommon manifestation of malignant disease. The relative paucity of splenic metastases is thought to be due to the properties of the spleen as an organ of immune surveillance. We report five cases of splenic metastases from carcinoma of the ovary demonstrated by CT scanning and ultrasound examination. In this series, splenic metastases were associated with bulk disease and more anaplastic tumours. Increased availability of magnetic resonance imaging may improve the recognition of splenic metastases.
