An Unusual Presentation of Prostate Adenocarcinoma Metastatic to the Oral Cavity

The lymph nodes and bones are the most common sites of metastases in advanced prostate cancer. However, an unusual clinical presentation or one that mimics another entity may make diagnosis difficult. We report a male patient with metastatic prostate cancer who presented with a primarily localized buccal tumor. Prostatic origin was highly suspected only after positive results of prostate-specific antigen staining from biopsy pathology. We share our clinical experience and review the literature. ? 2011 Taiwan Urological Association.
