Malignant Centroblastic-Histiocytic Lymphoma of the Skin

A mixed B-cell type centroblastic lymphoma with extraordinarily many histiocytes in a 68-year-old man is reported. Multiple skin tumours were the only clinical manifestation during the first 5 months. The disease then progressed to the lymph nodes, spleen, and parenchymal organs, but the bone marrow remained unaffected until death, 11 months after the onset of signs. C3d receptors were the only surface markers of the centroblasts. The histiocytes were normal with respect to morphology, muramidase staining, and Fc and C3b receptors. This highly unusual spread from skin to lymphoid and parenchymal organs is discussed in the light of lymphoid cell kinetics.     

Embolization of carotid cavernous fistulas via the superior ophthalmic vein

Background: Carotid cavernous fistulae are treatable by various means, one of which is embolization via the superior ophthalmic vein (SOV). The use of this technique over the past 12 years at the Royal Melbourne Hospital, Victoria, Australia, is reviewed.
Methods: Five patients with carotid cavernous fistulas were treated with embolization of the fistula via the surgically isolated SOV.
Results: Each patient had successful endovascular closure of the fistula using embolization via the SOV approach.
Conclusions: Treatment of certain types of carotid cavernous fistulas that cannot be closed by the conventional endovascular (arterial and venous) approaches can be successfully closed by using a transvenous approach through the SOV     

Computed tomographic angiography of the body

Large and medium-sized blood vessels can be identified on extracranial computed tomographic (CT) scans when a combination of infusion and bolus injection of conventional contrast material is administered. The cases illustrated in this report show that CT angiography can sometimes offer clinically useful information not present on CT scans obtained without contrast injection.
