A huge villous tumor of rectum: a case report.
Villous tumor of the large intestine was first identified and named by Holmes in 1858. It is said to account for 1.4 to 2.5 per cent of all tumors of the large intestine, but only sporadic cases have been reported in Japan. Although considerably large villous tumors are known to exist, reports refering to them, home and abroad, show that there are no more than 50 known cases which had diameters exceeding 10 cm1). This paper presents one of our recent experience of the tumor whose diameter reached 20 cm.
