Spleen.

The spleen is a forgotten organ.

Normal histology

  • Capsule.
  • Red pulp - red blood cells.
  • White pulp - white blood cells.
  • Marginal zone - between red pulp and white pulp.[1]

Images

  • Normal spleen (left) and splenic hamartoma (right). H&E stain. (WC)

Sign out

Micro

Sections show unremarkable splenic parenchyma. The nodules of white pulp are well-spaced and have germinal center formation. The red pulp has a normal vascularity and does not appear to be expanded. No nuclear atypia is apparent.

Gross pathology

The grossing of the spleen is dealt with in splenectomy grossing.

Overview of classic gross findings

Terminology Etiology Description Other
Ruptured spleen trauma hemorrhagic, capsule disrupted possible assocations mononucleosis, medical procedure - esp. colonoscopy,[2] others
"Lardaceous spleen"[3] amyloidosis waxy, pale, grey also see sago spleen
"Sago spleen" amyloidosis nodular, tapioca-like appearance also see lardaceous spleen
Splenic infarct vascular occulsion wedge shaped -- periphery -
