Background: Bone metastases are most commonly derived from lung, prostate, kidney, thyroid, or breast cancers. Colorectal origin is rare. Few studies have reported such metastases, with the axial skeleton being the most frequent site. Craniofacial involvement is exceptional. Case presentation: We report the case of a 73-year-old man in whom a right maxillary swelling and digestive symptoms were simultaneously discovered, revealing a metastatic rectosigmoid adenocarcinoma. Imaging, biopsy, and molecular analysis confirmed the diagnosis. The patient died three months after initiation of treatment, highlighting the poor prognosis associated with this rare presentation.
