[Functional splenic pathology and differential diagnosis in splenectomy]

Area of Science:

• Pathologic anatomy of the spleen
• Splenic immunology and function

Context:

• Splenic parenchyma comprises red and white pulp, with distinct roles in blood filtration and immune response.
• The marginal zone integrates innate and acquired immune responses.
• Most splenectomies are therapeutic, with only 10% posing diagnostic challenges.

Purpose:

• To discuss the diagnostic challenges in analyzing splenectomy specimens.
• To explore differential diagnoses for splenic pathologies based on clinical presentation.

Summary:

• Splenic red pulp filters blood, while white pulp and marginal zone manage immune reactions.
• Diagnostic evaluation of splenectomy specimens is crucial for identifying hematological diseases, splenomegaly, and splenic tumors.
• Clinical presentation guides the differential diagnosis of splenic conditions.

Impact:

• Enhances understanding of splenic pathology and diagnostic approaches.
• Aids clinicians in diagnosing complex splenic conditions.
• Improves diagnostic accuracy for hematological disorders and splenic tumors.
