Tongue metastasis of melanoma.

Malignant melanoma may metastasize to virtually any organs. Metastases to the oral cavity are uncommon and tongue metastases are very rare. The patient was a 79-year-old woman with cutaneous malignant melanoma. Lesion was widely excised and lymph node dissection was performed. She also had adjuvant chemotherapy. She is the unique malignant melanoma case who had recurrence on tongue 10 years later in literature. In conclusion, the prognosis of patients with tongue metastasis is poor and most of these patients have underlying widespread diseases.
