What is small blue lump on chest?

A small blue lump on the chest could be a variety of things, but some possibilities include:

* A sebaceous cyst: This is a noncancerous growth that develops from a blocked oil gland. Sebaceous cysts are usually round or oval, and they can range in size from a few millimeters to several centimeters. They are often filled with a cheesy or oily material.

* A lipoma: This is another noncancerous growth that develops from fat cells. Lipomas are usually soft and movable, and they can range in size from a few millimeters to several centimeters.

* A hemangioma: This is a benign tumor made up of blood vessels. Hemangiomas are often red or purple, and they can range in size from a few millimeters to several centimeters.

* A bruise: A bruise is a collection of blood under the skin that occurs when a blood vessel is damaged. Bruises are usually purple, blue, or black, and they can range in size from a few millimeters to several centimeters.

* A foreign body: Sometimes, a small blue lump on the chest can be caused by a foreign body, such as a splinter or a piece of jewelry.

If you are concerned about a small blue lump on your chest, it is important to see a doctor for diagnosis and treatment. The doctor may recommend a biopsy, which involves removing a small piece of the lump for examination under a microscope. This can help to determine the cause of the lump and to rule out any serious conditions.
