What could cause a hard movable lump under the skin on leg?
A variety of conditions can cause a hard movable lump under the skin on the leg. Some common causes include:
Soft tissue tumors: These are abnormal growths of tissue that form in the soft tissues, such as fat, muscle, or connective tissue. Soft tissue tumors can be benign (non-cancerous) or malignant (cancerous), and some of the more common types include lipomas, fibromas, and sarcomas.
Cysts: Cysts are fluid-filled sacs that form in the skin or deep tissues. They can develop due to various causes, such as a blockage in the ducts of a gland, trauma, or an infection. Sebaceous cysts, epidermoid cysts, and ganglion cysts are some common types of cysts that may occur on the legs.
Abscesses: An abscess is a collection of pus that forms in the body, and it may occur in the leg due to a bacterial infection. Abscesses can be painful and swollen, and they can be caused by various factors, such as an injury, surgery, or an infection in a nearby skin or bone.
Inflamed lymph nodes: Lymph nodes are small, bean-shaped organs that play a crucial role in the immune system. When there's an infection, inflammation, or another abnormality in the body, lymph nodes may become enlarged and palpable. Inguinal lymph nodes, located in the groin area, can become enlarged when there's an infection or inflammation in the legs or feet.
Hernias: A hernia occurs when an organ or fatty tissue protrudes through a weakness in the surrounding muscle or connective tissue. Inguinal hernias, where a part of the intestine bulges through a weak spot in the lower abdomen near the groin, can sometimes extend into the upper thigh or scrotum and may be felt as a lump.
Varicose veins: Varicose veins are swollen, enlarged veins that appear bluish or reddish beneath the skin. They are typically caused by weak or damaged valves within the veins, which can lead to the accumulation of blood and the formation of lumps or bulges on the legs.
Baker's cyst: Also known as a popliteal cyst, a Baker's cyst is a fluid-filled swelling behind the knee. It results from fluid buildup in a small sac called the popliteal bursa. Baker's cysts can develop in association with underlying knee joint conditions, such as arthritis or a meniscal injury.
It's important to note that while these conditions can cause a hard movable lump under the skin on the leg, it's not always possible to self-diagnose the exact cause. If you notice any unusual lumps or changes in your leg, it's essential to consult a healthcare professional for proper evaluation, diagnosis, and appropriate treatment if needed.
