Signet ring cell infiltration in tubular adenoma of ascending colon Academic Article uri icon


  • We present a case of signet ring cell infiltration in an adenomatous polyp of the ascending colon and review the literature. The patient had undergone resection of a mucin-producing adenocarcinoma of the proximal sigmoid colon seven months before the findings were reported. We presume that the signet ring cell aggregates are of metastatic origin.
