| pubmed-article:1208025 | pubmed:abstractText | The electron microscopy method was used to study one case of primary C-cell hyperplasia in 'hot' thyroid nodule of isthmus. Hyperplasia of the light form of C cells was found within nodule tissue. It suggests that C-cell hyperplasia within the nodule as well as in normal thyroid tissue plays a role preceding C-cell carcinoma. | lld:pubmed |
