Patient, male, 46 years old, farmer. The left submandibular mass was admitted to the hospital for 4 years. Four years ago, the patient found a broad bean mass under the left mandible, no pain, and the tumor gradually grew. He drove the tractor and accidentally overturned his car and hit the left lower jaw. The tumor grows rapidly. It has been ineffective with antibiotics and gradually grew to the size of the egg. A local hospital gave a puncture and the smear was diagnosed as “malignant melanoma.” Physical examination: Localized uplift of the left submandibular can touch two tumors of approximately 8×7×6 cm and 7×4×5 cm in size. The lesions are hard, uneven, and can be moved without tenderness. After the two cycles of chemotherapy with “cyclophosphamide” after admission, the “left submandibular mass and submandibular deltoidectomy” is performed under enhanced local anesthesia, and the tumor is complete during the operation.
