The influence of lymph node metastasis and ulceration of primary melanoma on germinal centers within draining lymph nodes: a histomorphometric study.
Microscopic counts and histoelectronic measurement of germinal centers in regional lymph nodes of melanoma patients showed a significant progressive increase in average number, as well as area, of germinal centers with occurrence of (adjacent) metastasis and presence of primary-tumor ulceration. The findings confirm in a quantitative manner the stage-dependent effect of progressive liberation of tumor antigen [10] on lymph node centers of humoral immune response.
