[Cytologic diagnosis of thyroid gland adenoma and goiter].

Examinations of smear impressions of postoperative biopsy specimens of the thyroid from adenoma patients have revealed among polygonal structures 1 to 20 spherical complexes (per micropreparation) consisting of relatively monomorphic follicular cells with intensively blue cytoplasm. The 'ball' size was 200-900 micron or more. Cellular composition, specific features of cellular structure, and the presence of spherical structures permit differentiating adenoma from goiter.
