Laryngeal metastasis from a signet ring cell carcinoma of the colon. A case report and review of the literature.

Secondary involvement of the larynx and pharynx by malignant neoplasms arising in contiguous structures is well known, but metastases to the larynx from distant tumors are rare. In the present paper a case of signet ring cell carcinoma of the transverse colon metastatic to the left pyriform sinus is reported. A review of the literature identifies 7 other published cases of metastases to the larynx from a colon carcinoma.
