Gross specimen measured 18 x 12 x 6 cm and cut surface showed multiple lobulated, solid, well-circumscribed nodules of variable sizes 1 cm to 7 cm diameter with areas of hemorrhage and cystic degeneration replacing most of splenic parenchyma (Figure 1).
(a) shows dilated, sinuous vascular channels surrounded by oval to spindle tumor cells, having scanty cytoplasm and hyperchromatic nuclei, mitotic figures occasional present (Hematoxylin & Eosin x200); (b) Reticulin stain (x200) shows intricate reticulum laid down around tumor cells and dilated vascular channels; (c) & (d) shows fibrous capsule of the tumor along with areas of necrosis (Hematoxylin & Eosin x50).

The microscopic examination on Hematoxylin & Eosin stain showed dilated, sinuous vascular channels surrounded by oval to spindle tumor cells having scanty cytoplasm and hyperchromatic nuclei, mitotic figures were occasional (Figure 2). The Reticulin stain showed intricate reticulum laid down around tumor cells and dilated vascular channels suggestive of hemangiopericytoma (Figure 2).
