Gingival and mandibular metastases from rectal adenocarcinoma: Case report and 20 year review of the english literature

Gingival metastases from non‐oral malignancies are very uncommon. The case is presented of a man with rectal adenocarcinoma, whose first clinical evidence of metastatic disease was a gingival metastasis. Although the prognosis of patients with gingival metastases is felt to be poor, prompt initiation of appropriate therapy may afford significant palliation. A 20‐year literature review of uncommon metastatic sites for rectal adenocarcinoma and non‐oral malignancies which can metastnsize to gingiva is briefly presented. Gingival metastasis should be included in the differential diagnosis of a gingival lesion in a patient with prior or current malignancy.
