Mucous cysts are a kind of Ganglion Cyst that
generally arises because of an underlying
arthritis of a joint. These cysts are common
causes of finger masses above the joint of the
small finger nearest to the tip. Aspirating the
cyst is the initial treatment, which should never
be tried at home. As the cyst connects to the
underlying joint, an infection occurring has the
possibility of spreading to the joint, thus
causing a serious problem. After aspiration,
almost 50% of the mucous cyst returns. As these cysts are benign, these can usually be
observed without any further treatment.
Retinacular cysts are tender masses that often appear in the palm near the base of a finger.
These are simple Ganglion Cysts that originate from the flexor tendon sheath of a finger.
Retinacular cysts often cause pain while gripping objects. Fortunately, these cysts are benign
and can be easily treated. Aspiration with a needle that removes the fluid from the core of
the cyst is the initial treatment. The cyst disappears if its walls are thin. A smaller and less
tender mass might still be present if the walls of the cyst are thicker. The mass is possibly not
a cyst if aspiration does not alter the cyst at all. In that case, an MRI scan and a surgical
excision might be considered.
Dupytren’s contracture is a kind of genetic disorder where the fascia of the hand gets
contracted as a result of which the fingers can no longer extend fully.
