Involvement of contiguous organs by a neoplasm is ordinarily evidence of aggressive malignant behavior. A patient presented with a bladder mass found to be arising in the cecum and diagnosed as a benign villous adenoma. Growth down a diseased appendix is proposed to explain the apparent extension of a relatively nonaggressive lesion into an adjacent organ.
肿瘤累及相邻器官通常是侵袭性恶性行为的证据。一名患者膀胱出现肿物，结果发现肿物起源于盲肠，诊断为良性绒毛状腺瘤。有人提出肿瘤沿着病变的阑尾生长，以此来解释一个相对非侵袭性的病变为何明显延伸至相邻器官。
