Angioma, in general, is dealt with in vascular malformations.

General

Features:[1]

  • Rare.
  • Benign.

Clinical:[1][2]

  • Pyrexia (fever), splenomegaly, weight loss, solitary hypodense lesion on imaging.

Note:

  • Littoral cells = line vascular channels of the red pulp.[1]
    • Littoral = related to shore.[3][4]

Microscopic

Features:[1]

  • Anastoming, small vascular channels.
  • Cystic spaces.
    • May have papillary projections.[2]
