Pleural malignant mesothelioma with metastatic deposition in the tongue.

A 70-year-old man with epithelioid malignant pleural mesothelioma was referred to the maxillofacial surgery department with a painful lesion on the lateral border of his tongue which interfered with swallowing. Physical examination demonstrated a 3 cm firm, non-ulcerated mass on the left lateral tongue, histologically shown to be metastatic epithelioid mesothelioma. MRI of the neck and CT scan of the thorax, abdomen and pelvis scans also demonstrated progressive local and metastatic disease.
