Ganglion cyst is a small benign ditzel classically found on the wrist.
General
- Very common.
- Most common tumour of the hand.[1]
- Classically on the wrist.[2]
- May be painful.[3]
- Many (~60%) regress if left alone.[4]
Gross
- Mass at a joint - classically in the hand.
DDx - clinical:
- Metacarpal boss - degenerative arthritis.[5]
- Giant cell tumour of tendon sheath.

Microscopic
- Empty space(s); usually multiple.
- Fibrotic wall.
- No epithelial lining.†
- +/-Myxoid change - very common.
- May have some spindled fibroblasts.
Note:
- † The entity is really a pseudocyst.[1]
DDx:
- Synovial cyst - true cyst (has an epithelial lining), villous projections into the cystic space.
- Juxta-articular myxoma.
- Myxoma.
- Other myxoid lesions.
- Digital mucous cyst - has many spindled fibroblasts, usu. superficial.[3]

SOFT TISSUE ("GANGLION CYST"), LEFT WRIST, EXCISION:
- GANGLION CYST.
Micro
The sections show fibroadipose tissue with cyst-like spaces surrounded by fibrous tissue. There are no villous projections into the cyst-like spaces. Focal myxoid areas are present with rare bland spindle cells. There is no nuclear atypia and no mitotic activity is appreciated. Dense connective tissue consistent with tendon is present focally.
