Myxoid cyst - Nail and Distal Digit
Compared with ganglion cysts, which are mostly found in people between the ages of 15 and 40 years, myxoid cysts are more prevalent in women between the ages of 40 and 70 years.
They are typically 3-10 mm in size, most commonly affect the second and third digits, and are seen more often in women than men. The most common presentation is a solitary myxoid cyst, but 2-3 cysts can be seen in some patients.
Myxoid cysts are benign, but patients may seek treatment if they become unsightly, cumbersome, or painful. A number of treatment options are available.
Myxoid cysts are uncommon in children but have been reported in patients as young as 12 years.
