A mucous or myxoid cyst arises from degeneration in the connective tissue overlying the joints of the fingers.
It may connect with the joint at the end of the finger.
The cyst has a smooth shiny surface and is commonly found at the base of the nail.
It often causes a groove in the nail, a few millimeters across which extends the length of the nail.
The cyst's size may vary. Jelly-like sticky fluid may be expressed from it (sometimes tinged with blood).
