Hodgkin's disease in the spleen. Investigation of Hodgkin foci and areas for the immune response.
Spleens with proven though small Hodgkin lesions were examined expecially in relation to the lymphoid tissue normally engaged in the immune response. These Hodgkin foci were always very close to small arteries and surrounded by a lymphocyte corona. Most of the red and white pulp seemed normal, but in some instances abnormal looking large and also multinucleated cells were found scattered through the p.a.l.s. and especially through some follicles. It is considered possible that these isolated cellular abnormalities in the white pulp, when associated with pre-existent Hodgkin foci, represent early Hodgkin lesions. The implications for the dissemination of the disease are discussed. Spread of malignant cells to the spleen is only acceptable within the concept of a homing principle. It is also possible that the lesions arise "de novo". The nature of the observed abnormal cells is not clear. An explanation for the origin of these Sternberg-Reed-like cells from B-lymphocytes would be in accordance with recent data, but another possibility still is that they originate from antigen trapping cells.
