2- to 3-mm nodules, our clinical estimate of
these tiny nodules was substantiated at surgery. All subjects except adults (one with
cancer) were found to have adenomatous
goiter. Figure 11 shows a typical muicro-
scopic picture of a nodule with the bizarre
characteristics of various size follicles, some
of which were cystic and filled with colloid,
others hemorrhagic, others microfollicular,
others macrofollicular, and some with hyperplasia with infolding of the epithelium.
This hyperplasia is demonstrated in Figure
