Summary

Oral cavity metastatic tumors derived from primary tumors from other corporal regions are rare, representing barely 1 % of all malignant tumors. Differential diagnosis of these lesions is challenging due to the wide spectrum of lesions with similar clinical presentation and especially when the presence of a primary tumor goes undetected. We present the case of a 55-year-old male with a painless tumor in the anterior maxillary region, vestibular gingiva and palate, with a 2-month evolution. Anatomopathological diagnosis was malignant clear cell tumor, highly suggestive of clear cell renal carcinoma metastasis, and the oral lesion constituted the first sign of illness.

KEY WORDS: oral metastasis, renal cell carcinoma, oral mucosa, maxilla.
