Types of lumps and lesions
Below are some of the most common types of lumps and lesions of the hand, but there are many more. If you have a lump or lesion of the hand and aren’t sure what it is, please contact us.
Characterized by a round mass that is filled with a jelly-like fluid, ganglion cysts are benign soft tissue lumps that commonly appear along the tendons or joints of the wrists or hands, but they may also develop in the ankles. Ganglion cysts are caused when fluid leaks from the joints, and if left untreated may cause stiffness and more limited motion.
Giant cell tumor
The cause of giant cell tumors is unknown, but may be due to overactivity of the parathyroid glands. These tumors are non-cancerous, but can still be harmful by destroying nearby bone. They typically appear on the middle or index finger and are characterized by a hard, solid mass that makes bending the finger difficult or painful. Surgery is usually the best option for giant cell tumors.
Epidermal inclusion cyst
An epidermal inclusion cyst is a benign tumor filled with keratin. It can sometimes appear where there was previously a wound such as a cut. Although they are typically painless, they can become inflamed and irritated, and many individuals also dislike their appearance and would prefer to have them removed.
Neuroma are non-cancerous tumors made of nerve cells that can develop after nerve trauma, such as a cut or blow. Neuroma may be painful, tender, or tingling when touched, and when they are severe enough, they may even limit the use of the hand. Some neuroma improve over time, but those that develop close to joints and remain painful may require surgical attention.
A fibroma is a benign lump that can greatly range in size and severity. Some will not bother the individual at all, while others can greatly impair one’s daily life. Although fibromas are slow-growing, they do often continue to increase in size — some even growing so large that they encompass an entire finger. Discomfort is also felt when they are touched or if pressure is applied to them. Fibroma lumps are more common in men than women, and typically develop in adults of middle age and older.
A lipoma is a characterized by a lump of non-cancerous fat cells. Although they are widely believed to be harmless, they may grow so large that movement in the hand or wrist is impaired.
