Granulation tissue forms when wounds heal.
Gross
- Looks granular, ergo the name granulation tissue.
Image
Granulation. (WC)
Microscopic
Features:
- Blood vessel rich - key element.[1]
- Small size ~ 25 micrometers in diameter.[citation needed]
- Proliferation of fibroblasts - key element.
- Inflammation - especially lymphocytes.
- Plasma cells common.
DDx:
- Mucocele.
- Pyogenic granuloma.
- Traumatized hemangioma.
- Prolapsed fallopian tube - rare complication following hysterectomy.[2]

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.
Alternate
The sections show a polypoid fragment of vascular and edematous tissue with a mixed inflammatory infiltrate consisting of plasma cells, neutrophils and lymphocytes.
No epithelial component is readily identified. No elements of fallopian tube are identified. No significant nuclear atypia is identified.
