Shape of lymph nodes generally depends on their topographoanatomical relations with surrounding organs, usually it is slightly oblong and flattened, a little prominent on the one side and minor pit on the other, resembling a bean. Sometimes shape of a lymph node may be roundish. In senile aged patients tape-like shapes of lymph nodes can be found, which may be regarded as a result of lesser nodes merging. In areas limited by fascias (for example in occipital region), nodes are more long than those located in loose tissue (for example, axillary).
