Lipomas and sebaceous cysts are both common types of skin growths that can be found underneath the skin. While they may look similar at first glance, they are quite different in nature and often require different types of treatments.
Lipoma:
A lipoma is a slow-growing, fatty lump that is generally encapsulated by a thin fibrous capsule. These growths can occur anywhere on the body, but they are most commonly found on the额头、颈部、肩部、背部、腹部、手臂和腿部。Lipomas are typically soft and doughy to the touch, move easily with slight finger pressure, and are typically smaller than 2 inches in diameter. They are usually painless and can be asymptomatic, but some lipomas can become tender or painful if they are压迫到附近的神经或血管。
Lipomas are caused by genetic factors and are usually noncancerous. They are not usually painful unless they are large or pressing on a nerve or blood vessel. Treatment for lipomas typically involves surgical removal, which involves making a small incision to remove the entire lipoma with its capsule. The incision is then closed with stitches. In some cases, larger lipomas or those with blood vessels within them may need to be removed in sections.
Sebaceous Cyst:
Sebaceous cysts are fluid-filled cysts that develop from the sebaceous glands, which are normally located on the scalp, face, ears, back, trunk, or groin areas. Sebaceous cysts can appear anywhere on the body but are most common on the head and neck.
Like lipomas, sebaceous cysts are generally painless and noncancerous. However, they can become infected, tender, or inflamed, causing symptoms such as redness, swelling, and pain. An infected sebaceous cyst may require antibiotics or drainage. If left untreated, a sebaceous cyst can become large and cause significant肿胀 or pain.
diagnosis and treatment
Diagnosing a lipoma or sebaceous cyst typically involves a physical examination, imaging tests like ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI), or a biopsy. Early identification of these growths is important to prevent them from becoming large or causing complications.
Treatment for lipomas and sebaceous cysts depends on the size, location, and whether they are causing discomfort or pain. Most lipomas and sebaceous cysts do not require treatment unless they become problematic. However, if a lump becomes painful, red, or swollen, or causes significant symptoms, surgical removal may be necessary.
prevention
There is no known preventive measure for most lipomas or sebaceous cysts. Regular检查和监测 can help detect these growths early before they become problematic.
Lipomas and sebaceous cysts are both common skin growths, but they are caused by different things and require different types of treatment. Lipomas are typically caused by genetics or fatty deposits under the skin, while sebaceous cysts result from blockages in the sebaceous glands. Both growths can usually be successfully treated with surgical removal, but preventing them from becoming troublesome is important. Regular medical check-ups and monitoring can help ensure that these growths remain asymptomatic and do not require treatment.
