Sample item

Which feature is most characteristic of anaplasia in malignant tumors?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Pleomorphism and hyperchromatic enlarged nuclei

Anaplasia is lack of differentiation and is marked by cellular pleomorphism, hyperchromasia, high nucleus-to-cytoplasm ratio, and atypical mitoses. It is a hallmark of malignant transformation.

Option by option

  • A. Encapsulation without invasion

    Encapsulation without invasion favors benign behavior.

  • B. Complete preservation of tissue architecture

    Architectural preservation is not typical of anaplastic malignancy.

  • C. Uniform mature cells with normal mitoses

    Uniform mature cells favor benign or well-differentiated tissue.

  • D. Pleomorphism and hyperchromatic enlarged nuclei (correct)

    Correct. These cytologic abnormalities indicate poor differentiation.
