Maxillary Gingival Metastasis from Adenocarcinoma Colon

[摘要] Background: Oral cavity metastasis from colorectal cancers is rare. Among these gingival metastases are extremely rare. Few cases of metastasis to mandibular gingiva have been reported. Here we report a rare case of maxillary gingival metastasis from adenocarcinoma colon. Case Report: A fifty-year-old gentleman underwent emergency laparotomy and sigmoid resection for obstructive growth in sigmoid colon and was diagnosed as adenocarcinoma colon, pT4N1. He received twelve cycles of adjuvant chemotherapy. After a disease-free interval of four years, he developed multiple visceral metastases along with an ulcero-proliferative lesion in maxillary gingiva, biopsy from which was reported as adenocarcinoma metastasis from carcinoma colon. He received palliative radiotherapy to the gingival lesion and is on systemic chemotherapy for disseminated disease. Conclusion: Gingiva being a rare metastatic site, a biopsy is warranted to differentiate it from second primary malignancies of oral cavity.                .
