Metastatic rectal adenocarcinoma in the maxillary bone: A case report

Abstract

Introduction: Colorectal cancer patients presenting with isolated bone metastases are exceedingly rare. Case Report: A 72-year-old male patient appeared with a painless gross swelling in the anterior maxillary gingiva, nearly a year after anterior rectal resection for cancer. The patient was submitted to lesion excision and nasolabial flap reconstruction. Histology revealed an intestinal type adenocarcinoma. The patient underwent radiotherapy. The disease spread and our patient lost his battle with cancer. Conclusion: Rectal tumor metastasis to maxillary bone is exceedingly rare and a high index of suspicion must be maintained in order to timely diagnose and treat it. Intraoral reconstruction with a nasolabial flap is a simple and fast procedure with good cosmetic and functional results.
