title: Ultrastructure, biological study and culture of C-cell carcinoma of the thyroid gland.
abstract: The ultra-structural of a C-cell carcinoma of the thyroid confirms previous data: the cells are slender, with a large nucleus. The Golgi apparatus is well developed. Granules in striking abundance are seen in every part of the cytoplasm: their diameter is 85 - 250 mmu.
