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.
起源于相邻结构的恶性肿瘤继发累及喉和咽是众所周知的，但远处肿瘤转移至喉则较为罕见。本文报告1例横结肠癌转移至左侧梨状窝的印戒细胞癌病例。文献复习发现另有7例结肠癌转移至喉的病例报道。
