This case documents a palliative partial glossectomy for a well-encapsulated tongue lesion ultimately diagnosed as metastatic breast cancer. The lesion was excised with 1-cm margins, and frozen sections were obtained from five orientations to ensure complete removal. Hemostasis was maintained with bipolar cautery. Closure was performed using absorbable sutures for durability in the dynamic oral environment. Postoperative pain was managed with local bupivacaine. The procedure prioritized symptom relief and margin control in the setting of advanced metastatic disease.
