Red pulp in splenomegaly syndrome: morphometric light and electron microscopy studies

Area of Science:

• Hematology
• Pathology
• Morphology

Background:

• Splenomegaly syndrome encompasses various hematologic disorders.
• Understanding red pulp morphology is crucial for diagnosing splenic conditions.
• Standardized morphometric analysis aids in disease differentiation.

Purpose of the Study:

• To compare spleen morphology in splenomegaly syndrome with controls.
• To investigate the red pulp changes in specific hematologic diseases.
• To correlate morphometric findings with erythrocyte shape and splenic function.

Main Methods:

• Standardized perfusion fixation and morphometric analysis of 33 spleens.
• Light and electron microscopy were employed.
• Comparison with control data and previous studies on hemolytic anemias.

Main Results:

• Splenomegaly syndrome, especially hairy cell and myeloproliferative diseases, exhibited disproportionate pulp cord volume increase.
• Erythrocyte volume density values aligned with scintigraphic splenic erythrocyte concentration.
• Cases with immunohaemolysis showed a high proportion of spherical erythrocyte profiles.

Conclusions:

• Splenomegaly syndrome involves significant red pulp morphologic alterations.
• Morphometry provides insights into splenic erythrocyte dynamics and pathology.
• Erythrocyte sphericity in splenomegaly suggests concurrent immunohaemolysis.
