The majority of lumps and bumps in the finger, such as the one shown in the picture, are benign in nature. They may arise from any of the structures in the finger, ie skin, subcutaneous tissue, tendon, nerve, blood vessels or even bone.
The diagnosis can be obtained through a detailed history and clinical examination, preferably by a Hand Surgeon. Further investigations may be required such as X-rays, ultrasound scans or MRI scans to evaluate the lump more closely before the treatment plan can be made.
The most common painless lumps and bumps in the finger from my experience are:
- Ganglion cysts arising from the joint or tendon sheath
- Pigmented villonodular synovitis, also known as giant cell tumour
- Hemangiomas
- Arteriovenous malformations
- Osteomas
