At macroscopy, the pathology report demonstrated that the spleen had a normal size with a weight of 182 g, the capsule was torn on multiple sides, and several subcapsular hemorrhages and hematomas were documented with a variable range from 4.5 cm to 2 cm (Figure 3).
10x EE: subcapsular hematoma (upper) and expansion of red pulp of the spleen that appears congested with multiple extravasated erythrocytes.

At microscopy, the white pulp showed normal compartmentalization of B and T lymphocytes, demonstrated also by immunohistochemistry (CD3 and CD20), and the red pulp showed sinuses normal in size but increased in number, with a slight decrease in chordal tissue and capillaries (Figures 4-6).
4x EE: expansion of red pulp and normal lymphoid follicles in the white pulp.

At microscopy, the white pulp showed normal compartmentalization of B and T lymphocytes, demonstrated also by immunohistochemistry (CD3 and CD20), and the red pulp showed sinuses normal in size but increased in number, with a slight decrease in chordal tissue and capillaries (Figures 4-6).
4x E-E: the capsule of the spleen is torn apart and a voluminous hematoma is compressing the spleen's parenchyma beyond it.
