    It's a Myxoid cyst, Simon... synovial fluid tracks along a sinus from a nearby IPJ joint capsule. Filled with silvery fluid/gel that causes blue/silvery appearance, although it may also appear darker if blood included. It can be drained, but may refill. Surgery might be necessary to obliterate the sinus. Usually cause no pain or distress and many folk simply live with them.

    I have drained a couple of these, some have refilled (although it took over a year) and some disappeared. Obviously in the location on your photo, pain due to pressure, and possibility of breakdown => infection have to be considered.

    Agree. Sometimes known as digital mucoid cysts, because they communicate with the IPJ they can be a portal to infection. Draining is usually ineffective since they readily fill again. As mentioned by John, surgery aims to close the sinus. (p1153 in my copy of McGlamry).

    True Bill.

    I have treated my share of these mucoid cysts. I would make a transverse elliptical incision over the dorsal DIPJT and remove the mucoid cyst with the ellipse and perform an arthroplasty of the DIPJT. Extreme care would be taken to not severe the digital arteries/nerves on the lateral side. I would remove the head of the intermediate phalanx to straighten the digit and provide room for closure. Never had recurrence.

    I have come across these and have had success in draining some, dressing them with antiseptic cream and not return but as mentioned some do. Even had one that a doctor referred to me as he did not know what to do, luckily that one cleared up after my intervention.
