Gastroesophageal junction adenocarcinoma metastasizing to gingiva

Malignant tumors rarely metastasize to the oral cavity and account for about 1% of all oral tumors. Metastasis to soft-tissue of the oral cavity is much rarer than jaw bones. Because of the rarity, metastatic tumors in the oral region are challenging for diagnosis. Primary tumors which metastasize to mouth are the most commonly lung, breast, and kidney. Oral cavity metastases represent distant spread and are associated with poor prognosis with short survival. We present a case of the gastroesophageal junction adenocarcinoma with metastasis to the oral soft-tissue.
