watered silk (moire silk)

watered silk appearance 

PATHOLOGY

A descriptive term for the wavy, loosely parallel fascicles of tumour cells seen by low-power light microscopy in granulosa cell tumours of the ovary and uterine leiomyomas, which has been fancifully likened to the fabric known as moire or watered silk

(I think it’s a bit of a stretch).
