Degenerative disc disease, abbreviated DDD, is a common ditzel, typically generated in the course of a discectomy operation.

Vertebral disc and discectomy redirect here.

General

• Herniated disc - causes back pain.
• May result in cauda equina syndrome.
• Composed of fibrous cartilage.

Microscopic

Features:

• Benign fibrous tissue.
• Nests of chondrocytes (as in immature cartilage).
• +/-Synovium with or without proliferation.
• +/-Neovascularization of disc material.
• Hemosiderin deposits (trauma or previous surgery).

DDx:

• Chondrocalcinosis (CPPD).
• Synovial cyst.
• Malignancy - very rare if not suspected.
  • Not reported in a series of 985 specimens.
  • Unexpected malignancy in 2 of 2177 specimens.
