Of the forms of carcinoma, cylinder-cell cancer is the most frequent.
Cases of complete occlusion constitute the rule in carcinoma, and the very great exception in ulcer.
It is most often observed in the sigmoid flexure and ccum, as are the other forms of carcinoma.
Carcinoma of the intestines appears either as cylindrical-cell cancer, as scirrhus, or as gelatinous or colloid cancer.
Arterial or mixed bleeding occurs in carcinoma and in rodent ulcer, and also from the stumps of badly-occluded piles.
The tumor is rounded in outline and nodular, and varies in size, density, and color according to the form of carcinoma present.
Stricture due to carcinoma of the intestinal wall occurs usually in the old or middle-aged, and the symptoms come on insidiously.
It is impossible during life to distinguish it from carcinoma.
Scirrhous, encephaloid and colloid forms of carcinoma occur.
Sarcoma is most often seen in the young; carcinoma in the middle-aged and elderly.
