Introduction

  • Papillary cancers that are 10 mm or less in maximal diameter are called micro papillary cancers:

    • The World Health Organization (WHO) classification suggests the term be used for incidentally discovered lesions.

  • Previously these lesions were called occult papillary cancers, because they were primarily incidental findings at autopsy or following thyroidectomy:

    • However, technological improvements in imaging have made the occult terminology obsolete, as micropapillary cancers are routinely imaged by high-resolution ultrasonography:

      • As a result, the detection of micro papillary cancers has reached epidemic proportions:

        • Accounting for 40% to 43% of the thyroid cancers excised

Prevelance

  • The high prevalence of micro papillary cancer has been appreciated from autopsy studies done decades prior to the emergence of high-resolution ultrasonography:

    • In the United States, these studies have shown up to a 13% prevalence of micro papillary cancer, whereas in other parts of the world substantially higher prevalence rates have been noted:

      • In Finland, the prevalence in one study was 36%.

    • The prevalence of micro papillary carcinoma in pathologic specimens is also highly dependent on how carefully one looks for it:

      • In one Spanish study, the initial prevalence based on grossly visible lesions was 5.3%, but when each thyroid was cut into blocks and carefully examined histologically:

        • The prevalence increased to 22%.

  • The prevalence of micro papillary carcinoma in some series was independent of age:

    • In Sweden the prevalence was approximately 7% for patients under age 50 or over age 80, and in Wisconsin in the United States the prevalence was 3% in an autopsy study of young adults.

  • Micro papillary carcinoma is frequently an incidental finding at the time of thyroid surgery and has been reported in 2% to 24% of surgical specimens.
