Lump in palm of hand can be frightening for some people as they begin thinking about something serious like a tumour as the cause of the lump. But, Lump in palm of hand can be caused by minor problems like hardening of the skin or infection or even a fluid-filled sac or cyst.
If you don’t have medical knowledge, you can’t find out the cause of the lump. So, you need to consult a healthcare professional to determine the cause of your lump.
Causes of Lump in palm of hand:
There are several causes of developing a Lump in palm of hand. Let us explore them below:
A callus is one of the most common reasons for the formation of the Lump in palm of hand. It can be seen in people who do repetitive works with hand. It can involve the usage of some instruments, tools, etc.
For example, if you happen to do gardening and use gardening tools more often, you can notice a callus or lumps in your hand. It can also be seen in people who play musical instruments. When you use tools with your hand, there is increased pressure on your hand. The skin of your hand gets irritation and starts to become thick and form a callus or lump.
A ganglion cyst is a fluid-filled sac or cyst which can develop over the joint like your wrist or the joints of your hand and fingers. A ganglion cyst is not a cancerous lump and it goes away or resolves on its own without treatment.
But if you place excess stress on the joint, it can enlarge further. In most of the people, ganglion cyst doesn’t cause pain. But if the cyst is large and it impinges on a nerve, it can lead to pain.
Tendon Sheath tumour:
Tendon is a connective tissue structure which connects the muscle to the bone. Tendon sheath is the thin layer or membrane that covers the tendon. There is a tumour which can form within this tendon sheath. It is a benign tumour and it does not spread to any other part in the body. It is generally without pain.
Majority of the lumps on the hand are harmless. But, sometimes there can be cancerous lumps on the hand as well. Some examples of such cancerous lumps are malignant melanoma of the skin and squamous cell carcinoma.
Their shape is irregular. So, if you see the growth of any irregular lump in your hand which is rapidly increasing in size, consult your physician without delay.
If you have had any injury to your hand, sometimes there is excess growth of the bone. It is called a bone spur. If you have any bone spur in your hand, you might feel like having a lump in palm of hand.
Dupuytren’s contracture is a condition in which there is the formation of thick tissue which extends from the hand into the finger. Due to this, the finger into which the tissue extends appears to be contracted or it appears to be bent towards the hand. It is painful in some people.
Epidermal Inclusion Cyst:
Epidermal Inclusion cyst is a sac-like structure under your skin which is filled with cheese or a wax-like substance called keratin. It is generally formed when you have any injury or trauma to your skin.
Whenever the skin is injured, the skin tries to correct the injured part, and in this process, keratinized skin cells are formed over the area and they are shed off later on. If they are not shed off due to any reason, they keep multiplying and form keratin filled sac called epidermal inclusion cyst.
In many people it is painless. But, if the cyst gets infected, it can become red, swollen and painful. In such cases, you will need to take antibiotics by consulting a physician.
The edges of our bones that form a joint are covered by an elastic tissue called cartilage. As we grow old, the elastic tissue called cartilage undergoes wear and tear. As a result, there can be inflammation or swelling in the joints which appears like a lump. If Osteoarthritis affects the joints of the hand, we can feel like a lump in palm of hand.
It is the condition in which there is inflammation or swelling of the joints. This type of arthritis develops due to our immune system fighting against our joints, which we call as autoimmune disorder. In this arthritis, there is the formation of the nodule or firm lumps under the skin. We can feel them as a lump in palm of hand.
Gout is a condition in which there is inflammation or swelling of the joints due to increased levels of uric acid in the blood. This uric acid gets accumulated in the affected joints. These inflamed joints can appear like a lump in the hand.
There are also some other causes of lump in palm of hand like developing trigger finger and carpal boss. I hope you have understood all the possible causes of lump in the hand.
