Mini-Symposium: Pathology of the SpleenVascular neoplasms of the spleen

The spleen is an enigmatic organ that for a long time was thought to be useless, it is anything but. Made up of two main functional units, the spleen plays an important role in the immune system (white pulp) and in blood filtration and removal of unwanted material (red pulp).Neoplasms of the spleen are either primary or secondary. Primary tumours can be lymphoid or non-lymphoid. This review is focused on the most common non-lymphoid tumours namely, the vascular neoplasm, which includes benign, malignant and intermediate grade tumours.
