Hand & Wrist

Mucoid Cyst

A mucoid cyst is a jelly filled-like cyst that usually develops or forms on any finger, around the first knuckle (called the distal interphalangeal joint or DIPJ).  

About Mucoid Cysts

On some occasions mucoid cysts can extend into the fingernail bed causing a nail deformity.  It usually presents itself as a small but sometimes painful nodule. Most patients that suffer from mucoid cysts, usually have a history of osteoarthritis or degeneration of the joint.

Signs & Symptoms

A mucoid cyst normally appears as a non-mobile nodule around the first knuckle of the finger. The cyst is normally soft to firm to touch, can vary in size and on occasion, can cause a nail deformity.  Larger mucoid cysts may be tender and painful, interfering with day to day activities.   

On consultation, Mr Lawson-Smith will do an examination of the finger combined with a past history and imaging studies (normally an x-ray is ordered prior to your appointment). Since the cysts are often associated with degenerative changes in the finger joint, it is important that the joint is evaluated so that any underlying condition can be addressed and the best treatment option is given to you.
