[Comparison of three pathologic classifications (Rappaport, LSG and Working Formulation) for the treatment of non-Hodgkin's lymphoma].

Comparison of three pathologic classifications (Rappaport, LSG and Working Formulation) was made for 292 cases of non-Hodgkin's lymphoma who were treated at the Department of Radiology, Tokyo Medical and Dental University, from 1952 to 1984. The Working Formulation was found to be the most convenient classification for the treatment of non-Hodgkin's lymphoma in Japan. There were two remarkable characteristics in the cases of non-Hodgkin's lymphoma classified by the Working Formulation. They were better case distribution having a strong relation to clinical prognosis and fewer high-grade cases in Waldeyer's ring lymphoma.

Buerger's disease (thromboangiitis obliterans): an analysis of the arteriograms of 119 cases.

One hundred and forty-four lower extremity arteriograms of 119 patients with Buerger's disease have been analysed. The 'corkscrew' appearance of collateral circulation was seen in 27.1% of 144 limbs affected by thromboangiitis obliterans, but in only 3.2% of 63 limbs affected by arteriosclerosis obliterans. We believe that the corkscrew vessel is highly characteristic of Buerger's disease and represents dilated vasa vasorum of the occluded main artery. The appearance of corkscrew vessels extending from the arterial occlusion sites to the periphery of the feet without opacification of the main pedal arteries indicated a poor prognosis.
