Summary

Spleens removed for trauma show significant differences from normal spleens, suggesting prior immunologic stimulation may contribute to traumatic rupture. These findings highlight unique pathological features in post-traumatic spleens.

Area of Science:

  • Pathology
  • Trauma Surgery
  • Immunology

Background:

  • The pathology of spleens removed due to traumatic injury is not well understood.
  • Traumatic splenic rupture often necessitates splenectomy or partial splenic procedures.

Purpose of the Study:

  • To investigate the gross and microscopic pathological features of spleens removed for traumatic injury.
  • To compare these features with normal control spleens.

Main Methods:

  • Analysis of 44 spleens from trauma patients and 10 normal control spleens.
  • Examination of gross morphology, including lacerations and hemorrhage.
  • Microscopic evaluation for inflammatory infiltrates, germinal centers, and other histological findings.

Main Results:

  • 86% of trauma spleens had capsular laceration/rupture; 68% showed microscopic parenchymal hemorrhage.
  • Trauma spleens exhibited increased germinal centers (77%), hyperplasia (55%), and marginal zone changes (41%) compared to controls.
  • No evidence of infection (e.g., Epstein-Barr virus), granulomas, or infarcts was found in patient spleens.

Conclusions:

  • Spleens removed for trauma display distinct pathological characteristics compared to normal spleens.
  • Prior immunologic stimulation may play a role in the susceptibility of spleens to traumatic rupture.
  • Post-traumatic spleens are not histologically equivalent to healthy spleens.
