Gross

  • Mass at a joint - classically in the hand.

DDx - clinical:

Microscopic

Features:[1][3]

  • Empty space(s); usually multiple.
  • Fibrotic wall.
  • No epithelial lining.†
  • +/-Myxoid change - very common.

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.

Alternate

The sections show 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. Benign glands are present.
