Sebaceous cysts on the front shoulder typically present as a painless lump that is movable beneath the skin. The cysts are often slow-growing and may vary in size. Although they are generally harmless, some cysts can become infected, leading to redness, tenderness, and the formation of pus. In such cases, medical attention is advisable to prevent complications and ensure proper treatment.

Individuals should refrain from attempting to pop or drain the cyst at home, as this can increase the risk of infection and scarring.

Medical professionals can diagnose a cyst on the front shoulder through a physical examination and, if necessary, imaging tests such as ultrasound. Treatment options depend on the size, symptoms, and whether the cyst is infected. In some cases, a healthcare provider may recommend watchful waiting, while others may require drainage, removal, or a combination of both. Removal of the cyst is typically a straightforward procedure that involves a local anesthetic to numb the area before making a small incision to extract the cyst.
