Summary

Accessory spleniculi, or ectopic spleen tissue, can appear in the chest due to developmental anomalies. This case highlights a patient with hereditary spherocytosis and prior splenectomy presenting with thoracic accessory spleniculi.

Area of Science:

  • Embryology
  • Anatomical Pathology
  • Hematology

Background:

  • Accessory spleniculi are splenic tissues found outside the spleen, often in the abdomen.
  • Thoracic accessory spleniculi are rare and typically associated with congenital anomalies or trauma.
  • Their presence without a clear cause warrants investigation into developmental origins.

Observation:

  • A 62-year-old woman with hereditary spherocytosis and a history of splenectomy presented with an incidental chest mass.
  • Imaging revealed an indeterminate mass, and needle biopsy provided an inconclusive diagnosis.
  • The mass was ultimately identified as ectopic splenic tissue within the thoracic cavity.

Findings:

  • The patient's thoracic mass was confirmed to be accessory spleniculi.

  • This finding is unusual given the absence of trauma and prior splenectomy.
  • The case suggests a potential embryological explanation for thoracic splenic tissue development.

    • Implications:

    • This case expands the understanding of ectopic splenic tissue locations.
    • It underscores the importance of considering developmental anomalies in diagnosing thoracic masses.
    • Further research into splenic embryogenesis may clarify such rare presentations.
