Tonsillar metastasis of primary signet-ring cell carcinoma of the cecum.

Metastatic carcinoma of the palatine tonsil is unusual. The most common primary sites of the tonsillar metastasis are the kidney, cutaneous melanoma, lung and breast. Primary manifestation of these tumors as a tonsillar mass is extremely rare in the literature. We present a case with a tonsillar metastasis from unusually localized primary signet ring-cell carcinoma of the cecum.
