What is a Lump on scalp behind ear?
A lump on the scalp behind the ear can be caused by a variety of factors. Some of the most common causes include:
* Sebaceous cyst: A sebaceous cyst is a noncancerous growth that develops from a blocked oil gland. Sebaceous cysts are often round or oval in shape and can vary in size from a few millimeters to several centimeters. They are typically painless, but they can become inflamed and tender if they become infected.
* Lipoma: A lipoma is a noncancerous growth that develops from fat cells. Lipomas are often soft and movable, and they can vary in size from a few millimeters to several centimeters. They are typically painless, but they can become uncomfortable if they grow large enough to press on nearby nerves or blood vessels.
* Hemangioma: A hemangioma is a noncancerous growth that develops from blood vessels. Hemangiomas are often red or purple in color, and they can vary in size from a few millimeters to several centimeters. They are typically painless, but they can become uncomfortable if they grow large enough to press on nearby nerves or blood vessels.
* Dermoid cyst: A dermoid cyst is a rare type of cyst that develops from embryonic tissue. Dermoid cysts can contain a variety of materials, including skin, hair, and teeth. They are typically located on the scalp or face, and they can vary in size from a few millimeters to several centimeters. Dermoid cysts are not typically painful, but they can become infected if they become damaged.
In some cases, a lump on the scalp behind the ear may be a sign of a more serious medical condition, such as skin cancer or a tumor. If you are concerned about a lump on your scalp, it is important to see your doctor for a diagnosis.
Your doctor will ask about your symptoms and examine the lump. They may also order imaging tests, such as an ultrasound or MRI, to get a better look at the lump and determine its cause.
Treatment for a lump on the scalp behind the ear will depend on the underlying cause. Some lumps may not require treatment, while others may need to be removed surgically.
