Gangion cyst

The most commonly accepted cause of ganglion cysts is the “herniation hypothesis”, in which they occur as “an out-pouching or distention of a weakened portion of a joint capsule or tendon sheath.” This is based on the observations that the cysts occur close to tendons and joints, the microscopic anatomy of the cyst resembles that of the tenosynovial tissue, the fluid is similar in composition to synovial fluid, and dye injected into the joint capsule frequently ends up in the cyst, which can become enlarged after activity.

An apparent misnomer, the ganglion cyst is unrelated to the neural “ganglion” or “ganglion cell”. (from wikipedia)
