Smears are cellular, featuring a background of lysed blood, crenated erythrocytes, and granular proteinaceous debris consistent with subacute hemoperitoneum. The histiocytic population is prominent and demonstrates significant scavenger activity, characterized by numerous hemosiderin-laden macrophages (siderophages) containing coarse, golden-brown refractile pigment, alongside occasional macrophages exhibiting active erythrophagocytosis. Scattered amidst the hemorrhage is a polymorphous population of small and large lymphocytes suggestive of splenic white pulp elements. Reactive mesothelial cells are frequent, appearing singly and in clusters with enlarged nuclei and prominent nucleoli, reflecting prolonged peritoneal irritation.
