  villous atrophy
  Example sentencesExamples
  Primary Infarcts.-Discrete areas of ischemic villous necrosis (primary infarcts) reflect obstruction to maternal - placental blood flow.
  Approximately 10 percent of biopsynegative villous adenomas contain invasive cancer, even if those with induration, ulceration, and other signs of malignancy are excluded.

  Tubular polyps are pedunculated, whereas villous adenomatous polyps have broad bases and are larger.

  The vascular endothelium was destroyed by villous proliferation and trophoblastic invasion in this vessel.
  In contrast to those of the large bowel, benign villous adenomas of the urinary tract are rare.
  Repeat gastroscopy showed macroscopic features consistent with coeliac disease and duodenal biopsies showed total villous atrophy.
  This becomes especially important when there is limited biopsy material from a distant metastasis that shows a small cell carcinoma and a colonic biopsy specimen that reveals a villous adenoma.
