Pathology of Thyroid Cancer

  • Georg Riccabona

Abstract

As mentioned previously many authors have described histological types of thyroid cancer since decades. The classification of thyroid neoplasms finally became so confusing that the International Union against Cancer (UICC) together with the World Health Organization (WHO) decided to tackle this problem and therefore a “new classification” of thyroid cancer was established (Hedinger, Sobin 1974). It has been widely accepted (Table 11) all over the world, because it helps pathologists in their difficult task of making a definite diagnosis, even as many centers feel, that the actual classification is missing several details (Hedinger 1983). The evolution of the actual classification is shown in Table 12 and in the context of this publication it does not seem justified to present the well-known classical examples of different tumor types, which can be studied in any textbook of pathology (Waldhart 1969). The discussion whether the actually valid classification of thyroid cancer types should also be accepted in the future, goes on in the scientific community (Williams 1980). Do a few papillae in a mixed thyroid tumor indeed justify the diagnosis of papillary carcinoma? Are onkocytic thyroid neoplasms essentially malignant? Where is the border between malignancy and benign thyroid adenomas, when no invasion of the vessels and/or capsule can be shown? (Fig. 4).
