الملخص EN

Background.

A case report of a nonhealing ulcer of the tongue histologically proven to be adenocarcinoma.

Method.

A 92-year-old man underwent clinical, immunochemistry, and imaging investigation.

Results.

Tests confirmed a distant metastasis of a primary colorectal carcinoma.

Conclusion.

Metastasis from colorectal carcinoma to the oral cavity is primarily to bone, but non-healing ulcers of the oral cavity should be considered in differential diagnoses.
