These are a very common incidental findings in older dogs that can occasionally be mistakenly for malignant masses. They consist of nodules of hyperplastic white and red pulp

- usually 1-2 cms in size, but occasionally may be larger
- spherical
- protrude hemispherically from the surface as yellow and red mottled nodules

Rarely these nodules may rupture and give rise to haemorrhage.

Haemangiosarcoma

Haematopoietic Neoplasms

Lymphosarcoma
myeloid (granulocytic) leukaemia
  • rare
  • all species
  • extreme form with spleen approaching liver size
systemic mastocytosis
  • cat
  • extreme form with spleen approaching liver size
