Ganglion cyst

Most common benign lesion of the hand/wrist.

Typically, insidious onset with no predisposing conditions.

Usually only a cosmetic problem but local pain and neurovascular compression may occur.

Conservative management usually suffices if no neurovascular compromise.

Aspiration of dorsal cysts can be therapeutic and diagnostic.

Surgical excision has a higher rate of resolution but recurrence is possible.

No reported malignant transformation.

Ganglion cysts are smooth, soft, benign masses that are usually located on the wrist (dorsal or volar aspect) with one or more communicating stalks into the wrist joint or surrounding structures. They can be single or multiloculated and are filled with viscous, sticky, mucinous fluid.
