Hodgkin's disease occurring in monocytoid B-cell clusters.
The authors report three cases of Hodgkin's disease (HD) occurring in monocytoid B-cell (MBC) clusters within lymph nodes, a finding heretofore not published. MBC clusters were found mainly in a perisinusoidal and perifollicular distribution in all three cases. Within some of the MBC clusters of each case, small foci of overt necrosis were evident. Sternberg-Reed cells or their variants were found adjacent to all of these foci, as well as within some MBC clusters that were free of necrosis. These findings suggest that the presence of necrosis within MBC clusters has diagnostic utility. In two cases, evidence of HD was detected only within MBC clusters and nowhere else. In the third case, HD was found primarily within MBC clusters. These observations imply that HD arose within MBC clusters. Minimal involvement of lymph node by HD can occur within MBC clusters and should be recognized as such on the basis of morphologic features. The earlier a diagnosis of HD can be made, the better is the patient's outlook for survival.
