Pain, swelling, bluish discoloration Paroxysmal hand hematoma , also known as Achenbach syndrome , is a skin condition characterized by spontaneous focal hemorrhage into the palm or the volar surface of a finger, which results in transitory localized pain, followed by rapid swelling and localized blueish discoloration .
Infectious tenosynovitis in 2.5% to 9.4% of all hand infections. Kanavel's cardinal signs are used to diagnose infectious tenosynovitis. They are: tenderness to touch along the flexor aspect of the finger, fusiform enlargement of the affected finger, the finger being held in slight flexion at rest, and severe pain with passive extension.
Bone marrow oedema is seen at the tendon insertion (short thin arrow). (b, c) T1 weighted images of a different section of the same patient, before (panel b) and after (panel c) intravenous contrast injection, confirm inflammation (large arrow) at the enthesis and reveal bone erosion at tendon insertion (short thin arrows).
Finger sprains occur when the ligaments which are attached to the bone are overstretched and this results in pain, swelling, and difficulty for moving the finger. Common examples of a sprain are jammed or twisted fingers. These injuries are common among ball players but can also occur in laborers and handy men.

Diffuse TGCT is locally aggressive and can spread to surrounding tissues, causing bone erosion and tissue damage. If not treated early, it can spread to areas outside the joint, extra-articular, and potentially cause permanent loss of range as well as intense pain. [10] [11]
