There's a lump next to my ear.

Ear next to a flesh lump may be epidermoid cyst, often manifested as a hemispherical bulge mass, slow growth, normal skin color, texture hard, elastic, can move, about 0.5 cm to a few centimeters in diameter, no self-conscious symptoms. Cysts generally grow slowly, to a certain extent will not grow. Another condition is sebaceous nevus, which is caused by abnormal skin development. The normal main component is sebaceous glands. It shows as localized yellowish patches with hairless surfaces, slightly raised, smooth and waxy luster. Both conditions require surgery.
