What causes hard node in arm?
Patient: Small (0.1 in) hard node just above elbow in my upper, inside arm. Very movable, smooth, and pretty round. I'm concerned with how hard it is. Its like a hard grain of rice, only not elongated. Nothing on my medical history. Male, mid 20's, white, otherwise healthy. Just concerned. Been watching it for two weeks and haven't noticed any changes. Doctor: This is neurofibroma. A benign condition. Requires removal if it is causing pain, compressing other structures or is disfiguring. General surgeons remove them under local anesthesia.
