Cists are commanlly found behind the ear? i have noticed in my findinds this is comman?

A doctor has provided 1 answer

They can: Two types of cysts commonly occur underneath the skin, epidermoid cysts and sebaceous cysts. Both usually appear as flesh-colored or whitish-yellow smooth-surfaced lumps. Epidermoid cysts form when surface skin cells move deeper into the skin and multiply. These cells form the wall of the cyst and secrete a soft, yellowish substance called keratin, which fills the cyst. Sebaceous cysts form inside.
