There are several possibilities, including an enlarged lymph node (which can be caused by either benign or malignant changes in the lymph node), parotid (salivary) gland tumor, and skin cysts, among other possibilities.
Unfortunately, you will need to be evaluated by a physician in order to obtain an accurate diagnosis.
