Borderline Lesions, Pseudomalignancy, and Mimicry

  • J. C. E. Underwood


Errors are, unfortunately, not at all uncommon in biopsy diagnosis. They may be due to observer error (Chap. 1), sampling error (Chap. 2), or because the morphological features of one disease either overlap or mimic those of another (Chap. 4). The practical importance of this last point is emphasised in this chapter. A distinction will first be drawn between the concept of borderline lesions, where two or more named conditions (diagnoses) occur within the same continuous disease category, and genuine mimicry, where two or more diseases share morphological similarities despite the fact that they are entirely separate entities.
