Ganglion Cyst (Gideon’s Disease)

In surgery, ganglion – colloquially called overleg – (hygroma; ICD-10-GM M67.4: ganglion) refers to a benign (benign) neoplasm arising from the tendon sheaths. Tendons or the joint capsule. The interior is often stapled.

Ganglion frequently occurs in the wrist or finger joints and less commonly in the foot, knee, elbow, or shoulder. In the hand, ganglia represent the most common benign tumor formation, accounting for 50-70%.

In neurology, ganglion refers to a collection of nerve cells.

Sex ratio: males to females is 1: 3.

Frequency peak: The disease occurs predominantly between the ages of 10 and 50. In younger people, the incidence increases and peaks between the ages of 20 and 30.

Course and prognosis: Often a ganglion regresses spontaneously (on its own). If the ganglion causes little discomfort, an initial attempt can be made to achieve regression by immobilizing the joint. If the discomfort is more severe and mobility is restricted by the ganglion, surgery may ultimately be required.

The ganglion often recurs due to renewed overuse. The recurrence rate is 20-30% after surgical removal.
