Özet
Colorectal carcinoma is observed as the second most common cancer in women and the third most common cancer in men. These lesions may show the macroscopic appearance of a polypoid vegetating mass or of a flat infiltrating lesion. These tumours are mostly adenocarcinomas (96%), and they show a mucinous component in some cases. The signet ring cell carcinoma, squamous carcinoma, undifferentiated neoplasms and medullary-type adenocarcinoma (solid carcinoma with minimal glandular differentiation or slight cellular pleomorphism) are the rare malignancies of the large bowel. Colorectal carcinoma can be graded into well, moderately and poorly differentiated lesions, but there is only little evidence supporting that grading may help evaluating the prognosis of affected patients. In our chapter, pathologic features of colorectal carcinoma are given with detailed knowledge.
