Myxoid Cyst:
Information for adults

The most common location for myxoid cysts is the fingers. They are usually found near the base of the nail, slightly off to one side or the other. Occasionally, myxoid cysts can occur beneath the nail or involve the root of the nail. When this happens, changes in the nail, such as grooves, depressions, or slight color changes, may be seen. Rarely, these cysts involve the fat pad of the fingertip. 

The lesion is a solitary, rounded, flesh-colored, or translucent bump or nodule that may feel relatively firm or may feel more fluid-filled (fluctuant). The fluid inside myxoid cysts is thick, sticky, and clear to yellowish in color.
