Types of Skin Lumps and Bumps
Skin lumps and bumps can be broadly categorized into several types, including cysts, lipomas, warts, and skin tags. Each type of growth has its own unique characteristics and causes.
Cysts
A cyst is a closed capsule or sac-like structure that can be filled with fluid, semi-solid material, or gas. Cysts can occur anywhere on the skin and can range in size from small to large. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, cysts are common and can be caused by a variety of factors, including genetics, skin trauma, and clogged pores.
| Type of Cyst | Description |
|---|---|
| Epidermoid Cyst | A benign cyst that forms in the epidermis, the outermost layer of the skin. |
| Pilary Cyst | A benign cyst that forms in the hair follicle. |
| Sebaceous Cyst | A benign cyst that forms in the sebaceous gland. |
Lipomas
A lipoma is a type of benign tumor that forms in the fatty tissue under the skin. Lipomas are usually soft and movable and can occur anywhere on the body. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, lipomas are common and can be caused by a variety of factors, including genetics and hormonal changes.
Lipomas are typically diagnosed through a physical examination and may require imaging tests, such as an MRI or CT scan, to confirm the diagnosis. Treatment for lipomas usually involves surgical removal, but in some cases, they may be left alone if they are not causing any symptoms.
Warts
Warts are small, rough growths that can occur anywhere on the skin. They are caused by the human papillomavirus (HPV) and can be spread through skin-to-skin contact. According to the Centers for Disease Control and Prevention, warts are common and can be treated with a variety of methods, including over-the-counter medications and surgical removal.
| Type of Wart | Description |

| Common Wart | A small, rough growth that can occur anywhere on the skin. |
