Though villous adenomas are less common than adenomatous polyps , they are much more likely to have invasive carcinoma in them ( about 40 % of villous adenomas ) 雖然絨毛狀腺瘤不如腺瘤息肉那么常見,但更有可能惡變為癌(大約40 %的絨毛腺瘤) 。

Microscopically , a villous adenoma is shown at its edge on the left , and projecting above the basement membrane at the right 顯微鏡下,左側見絨毛狀腺瘤邊緣,右側見突破基底膜。

The neoplastic glands are long and frond - like , similar to those seen in a villous adenoma 腫瘤腺體長并呈葉狀,與絨毛狀腺瘤所見相似。

A villous adenoma averages several centimeters in diameter , and may be up to 10 cm 絨毛狀腺瘤直徑一般幾厘米,可以達到10個厘米。

The edge of the carcinoma arising in the villous adenoma is seen here 圖示絨毛狀腺瘤惡變的癌邊緣。

There are few villous pe - la stomas , and they sink 絨毛白蠟氣孔較少,下陷。
