A number of conditions can be responsible for a lump on the inner thigh under skin. Such a lump will develop in form of an inflammation, bulge, tumor or even a nodule. You can have a single lump or several of them in a cluster. Some are painful while others are painless. They can also be tender, soft, hard or cystic.
Benign lumps on the inner thigh require no treatment. Ones caused by infections or showing signs of malignancy require immediate medical treatment. Lumps on the inner thigh can develop in male and female.
Hard lump on inner thigh; sebaceous and epidermoid cysts
Sebaceous cysts are also referred to as epidermoid cysts. The two are closely related but not similar. Epidermoid cysts are more common. They are common causes of hard lump on the thigh under skin. Both types of cysts can occur anywhere on skin. In fact, they can be responsible for formation of a lump near esophagus.
Epidermoid cysts develop when the upper skin cells move deeper into skin instead of getting shed off normally. This is usually caused by damage on hair follicles or skin. The skin cells secrete keratin, a tough substance which forms the walls of the cyst. Sebaceous cysts form when oil-producing glands under the skin become clogged sebum.
Epidermoid cysts appear yellowish on close observation. This is because of presence of keratin. They are filled with a thick substance that sometimes drains. The fill-in material is usually smelly.
Like most cysts, epidermoid and sebaceous cysts grow slowly. They eventually form a small, round lump on the inner thigh under skin. If infected, the skin covering the cyst lump will swell, redden and become tender. You can have a lump behind nipple caused by a sebaceous cyst. This is because the nipple also contains hair follicles on the surface of its skin.
Epidermoid cyst lump can be drained in a clinic by your doctor. Draining involves making a small incision and squeezing fill-in fluid out. Cyst lumps are known to return after this treatment.
Anti-inflammation medications can also be delivered through injections. To keep a cyst lump from recurring, surgical removal is the best treatment approach.
Painful lump on inner thigh
Infections are common causes of painful lump on the inner thigh. They include:
Boils and abscesses
A boil is a pus-filled lump that forms under skin. Boils are always painful. A large boil is known as an abscess. Initially, boils appear in form or red bumps that are painful and itchy. As it fills with pus, it swells and forms a white tip. Due to presence of bacteria, boils may be accompanied by other symptoms such as fever and fatigue. An abscess can also develop from an infected razor bump. It can also occur after skin injury or piercing. Boils and abscesses are common causes of lump inside earlobe after piercing.
Herpes is the most common STD that may cause small, red, blisters on the inner thighs. Herpes virus on the inner thighs will be contracted if the outer skin is damaged or cracked. Another common STD that may cause a tender lump on inner thigh is HPV, which is the virus responsible for warts. Warts form soft lumps that resemble a cauliflower. They take the color of skin and are often not painful but can be itchy. Syphilis is usually characterized by appearance of a sole painless lump in the genital region. Fleshy colored lumps with a dimple-like structure on top are signs of Molluscum Contagiosum.
Folliculitis is defined as inflammation of hair follicles. It is a bacterial infection. Folliculitis will result in multiple, painful, red bumps on inner thighs. Poor shaving methods encourage folliculitis bumps. For this reason, it is common to have a lump above genital area after repeated shaves.
This condition causes itchy, red bumps on the inner thighs. It occurs when hair follicles, through which sebum is secreted, clog with dead skin, blood clot and sebum. Bacteria invasion leads to inflammation and itchiness.
Jock itch is almost exclusively a male fungal infection. The main symptom of jock itch is formation of very itchy rash on the inner thigh and near the groin. The bumps may also fill with pus.
Heat rush or miliara
If you have a habit of wearing tight underpants, your inner thighs may suffer from heat rash. This is a condition that causes red bumps due to blocked sweat pores.
Injuries, trauma or insect bites
Naturally, the skin gets inflamed after an injury or a form of trauma. This is common after insect bites or after pinching. Allergic reactions can also result in inflammation on inner thigh. Lumps formed this way disappear in a few days.
A lump on the inner thigh can get painful to an extent of causing difficulty walking. It can also cause swelling on leg or nearby regions such as groin and genitals. If this happens, you should get medical help immediately.
Lump on inner thigh that is not painful
It is not always the case that a lump on the inner thigh will be painful. Keratosis pilaris is a condition that causes small white bumps on inner thighs, cheeks and buttocks. These bumps are not painful.
A hard painless bump near the groin can also be a hernia. A hernia occurs when an internal organ or tissues protrudes through a weakened area on the surrounding wall that covers it. It is common near the groin region. Lump in groin area male symptoms due to hernias can occur in infants. This is because of the weak spot left behind when testicles are descending. The symptoms usually resolve in a few weeks.
Another condition that may cause a painless lump near inner thigh is saphena varix. It is a disorder of blood vein valves. Just like a hard lump near anus caused by hemorrhoids, this condition is not fatal but can be discomforting.
If you notice a soft, rubbery lump under skin on the inner thigh, it most likely is a lipoma. Lipoma lumps form due to accumulation of fat cells under skin. If pressed with a finger, the lump will move. These lumps are very harmless and require no treatment.
Is a hard lump on inner thigh a sign of cancer?
A hard lump on the skin or under skin that keeps growing should cause you concern. A good example is a red or brown mole-like lump that keeps changing in size and color. Malignant tumors are not always hard. A good example is a soft tissue sarcoma.
Soft tissue sarcoma can start anywhere in the body. Initially, no noticeable signs will occur. This is largely because tumors follow an almost normal tissue growth process.
The first symptom of a soft tissue sarcoma is formation of a painless lump. This mostly happens in elastic body tissues that are deep under the skin. A lump on left side of stomach no pain symptoms for example can be caused by sarcoma. It should not be confused with a lipoma. Lipomas do not keep growing in size and are also not painful. As the sarcoma lump grows large, it pushes neighboring tissues. With time, it will press against a nerve and cause pain. Cancer cells are known to spread to other body parts as it advances. This can lead to formation of lumps elsewhere in the body. Other symptoms include swollen lymph nodes and unexplained weight loss.
Diagnosis for malignancy involves use of X-rays, MRIs and biopsies. Your doctor will ask you some questions that may help confirm diagnosis.
Treatment for malignant tumors is more successful if started early enough. It is for this reason that you are advised to get medical help immediately you notice signs of malignancy. A therapeutic treatment approach is usually settled for when treating cancer.

When to see a doctor
A cyst lump doesn’t require medical treatment. However, cysts rarely disappear completely if not removed. See your doctor if the cyst is causing some form of discomfort and calls for removal.

Painless lumps can be left to resolve without medical treatment. Conditions such as Keratosis pilaris can be managed with home remedies and treatments. Your doctor can however prescribe more effective OTC medications to better manage such conditions.
