[31F] Concerns about a hard, non-painful back lump

What might be happening

Based on the information you've provided, possible explanations for the lump on your back include:

• Lipoma: A lipoma is a slow-growing, fatty lump that's most often situated between your skin and the underlying muscle layer. They are typically soft and movable under the skin, and are generally not painful.

  • Treatment: Lipomas usually do not require treatment unless they become painful or restrict movement. They are usually removed for cosmetic reasons, if they grow larger, or for biopsy to rule out more serious conditions.

• Dermatoid cyst: Dermoid cysts are benign tumors that contain structures such as hair, fluid, teeth, or skin glands. They can be present at birth, but may not be noticed until later in life.

  • Treatment: Dermoid cysts are typically removed surgically due to the risk of rupture or torsion.

• Sebaceous cyst: Sebaceous cysts are small, noncancerous bumps under the skin. They can appear anywhere on the skin and are often caused by swollen hair follicles.

  • Treatment: If a sebaceous cyst does not cause problems or look bad cosmetically, then you probably will not need treatment. If it becomes swollen, tender, or large, your doctor may drain it or perform a minor surgery to remove it.

• Abscess: An abscess is a painful collection of pus, usually caused by a bacterial infection.

  • Treatment: Abscesses are typically drained by a healthcare professional. Antibiotics are not usually needed.

Please note that it's important to have any new lump evaluated by a healthcare provider, especially if it's hard, doesn't move easily under the skin, or has grown rapidly.

What you can do

1. Monitor the lump: Keep an eye on the size, shape, color, and any other characteristics of the lump. If it changes or if new symptoms develop, make note of them.
2. Over-the-counter treatments: If the lump is causing discomfort or itchiness, over-the-counter treatments such as hydrocortisone cream might provide some relief. However, these treatments will not treat the underlying cause of the lump.
3. Seek medical attention: It's important to have the lump evaluated by a healthcare provider. They can examine the lump and may order further tests, such as a biopsy, to determine the cause.

What you should look out for

Reasons to seek immediate medical attention:

• If the lump grows rapidly or changes in color, size, or shape
• If the lump becomes painful, hot to the touch, or starts to drain fluid
• If you develop a fever or other new symptoms
• If the skin over the lump breaks open or becomes ulcerated
