The sections show vascular tissue with plump fibroblasts, reactive endothelial cells

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.

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.

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.
