The parotid and submandibular glands are susceptible to benign or malignant tumors that often appear as a lump in front of or below the ear. Parotid and submandibular gland tumors including lymphomas, melanoma, or squamous cell carcinoma, can spread from other areas of the body to enter the gland through the lymphatic system. Fortunately, in most cases, the tumors are easily removed with surgery.
