title: Intraluminal meniscoid ulcer in the colon: an unusual sign of malignancy.
abstract: An unusual sign of malignancy in the colon is described, consisting of an intraluminal lenticular ulcer surrounded by a meniscoid lucency of tumor. This constellation of findings was first described by Carman as a specific indicator of gastric malignancy. An aggressive ulcerating lesion with these characteristics, while rare in the colon, raises the suspicion of carcinoma.
