Colon mass: a rare site of metastasis for squamous cell cancer of the head and neck.

A 61-year-old man with a past medical history significant for heavy alcohol consumption and an extensive smoking history presented with a left neck mass which was diagnosed as a pT3N2bM0 squamous cell carcinoma (SCC) of the submandibular gland. The patient was later found to have recurrence with mediastinal metastasis despite adjuvant chemoradiation. He subsequently developed abdominal distention with computed tomography revealing an ascending colon mass and findings concerning for perforation. The patient underwent an exploratory laparotomy with right hemicolectomy. Surgical pathology was consistent with metastatic SCC.
