핵심 개념

• Ganglion Cyst — A benign, fluid-filled cyst that commonly arises from joint capsules or tendon sheaths, often associated with mucoid degeneration and not lined by epithelial cells.
• Mucoid Degeneration — A pathological process where connective tissues undergo changes leading to the accumulation of mucinous material, which is a key mechanism in the formation of ganglion cysts.
• Joint Capsule — A fibrous structure that encloses a joint, providing stability and containing synovial fluid; its degenerative weakening can contribute to ganglion cyst development.
• Tendon Sheath — A synovial-lined sheath surrounding tendons that reduces friction during movement; degeneration here can lead to cyst formation through mucoid changes.
• Pseudocyst — A cyst-like structure that lacks a true epithelial lining, such as a ganglion cyst, distinguishing it from true cysts in pathological terms.
