===Micro=== | |||
The core shows rare, spaced, atrophic appearing glands, mostly with a wavy border and a decreased quantity of cytoplasm. Prominent nucleoli and significant nuclear enlargement are not identified. | |||
There are none of the following: mitoses, adjacent PIN, suspicious luminal material, nuclear hyperchromasia. | |||
