Giant cells of the tendon sheath are more prevalent in the hand and should be considered when there is a painless mass, single or multiple, in the form of a bean-like or nodular elevation on the hand. The size of the mass varies from a few millimetres to several centimetres. The masses are hard to the touch and usually have no significant pressure pain. If any of these abnormalities are present, prompt medical consultation and a definitive diagnosis by a medical professional is recommended.
