The spleen is a forgotten organ.
Normal histology
- Capsule.
- Red pulp - red blood cells.
- White pulp - white blood cells.
Splenic enlargement
- Portal hypertension (e.g. cirrhosis).
- Lymphoma:
- Hairy cell leukemia.
- Splenic marginal zone lymphoma.[1]
- Splenic diffuse red pulp small B cell lymphoma.[2]
- Mononucleosis (EBV infection).
- Hemophagocytic syndrome.[3]
Hyaloserositis
- Properly referred to as hyaloserositis of the spleen.
- Capsule of the spleen is white - resembles sugar-coating; also known as sugar-coated spleen.[4]
- Importance: none - benign.
Image(s):
Mononucleosis
General
- EBV infection.
- Massive splenic enlargement.
Microscopic
Features:
- Atypical lymphoid cells.
Littoral cell angioma of the spleen
- For angioma see vascular malformations.
General
Features:[5]
- Rare.
- Benign.
- Pyrexia (fever), splenomegaly, weight loss, solitary hypodense lesion on imaging.
Note:
Microscopic
Features:[5]
- Anastoming, small vascular channels.
- Cystic spaces.
- May have papillary projections.[6]
Images:
- LCA - low mag. (webpathology.com).
- LCA - high mag. (webpathology.com).
- LCA - very low mag. (WC).
- LCA - intermed. mag. (WC).
- LCA - very high mag. (WC).
