Granulation tissue forms when wound heal.

Gross

  • Looks granular, ergo the name granulation tissue.

Microscopic

Features:

  • Blood vessel rich - key element.[1]
  • Proliferation of fibroblasts - key element.
  • Inflammation - especially lymphocytes.

URINARY BLADDER, BIOPSY:
- REGENERATIVE EPITHELIUM, INFLAMED SUBEPITHELIAL TISSUE AND GRANULATION TISSUE.
- NO MUSCULARIS PROPRIA.
- NEGATIVE FOR MALIGNANCY.

Micro

The sections show vascular tissue with plump fibroblasts, reactive endothelial cells and a mixed inflammatory infiltrate (granulation tissue). Focally, a dense cluster of neutrophils is seen at the luminal aspect.

A single layer of epithelium with pale, plump nuclei is present without apparent mitotic activity. Inflamed subepithelial tissue is present. No stratified urothelium is identified. No significant nuclear atypia is present.
