The colorectal cancer frequently metastasizes to the liver, lung, peritoneum, bone, ovaries, and the adrenal glands. Neck met-astasis from colorectal carcinoma, however, is extremely rare. We experienced a case of rectal cancer presenting with neck rior resection with lop T-colostomy for adenocarcinoma of rectum. Six months later, he presented with palpable mas on the left neck, which progressively increased in size. CT scan showed a 4× 3.5× 2.5 cm-sized mass on the level Ⅲ, ⅣB of left neck with sternocleidomastoid muscle infiltration. There was no evidence of distant metastasis. But biopsy of the mass revealed metastatic adenocarcinoma, and the histologic findings were similar to that of the primary rectal adenocarcinoma. (Korean J Otolaryngol 2002;45:519-21)
