Mediastinal pancreatic ectopia, a rare condition, typically involves small cysts. This case highlights a unique presentation of ectopic pancreas as a large, solid mass in the anterior mediastinum of a teenage male.

Area of Science:

  • Developmental biology
  • Gastroenterology
  • Thoracic surgery

Background:

  • Ectopic pancreas is a congenital anomaly, usually found in the gastrointestinal tract.
  • Mediastinal pancreatic ectopia is an exceedingly rare variant, with limited documented cases.
  • Previous reports describe mediastinal pancreatic tissue within cystic masses or cyst walls.

Observation:

  • A 17-year-old male presented with a large, solid mass in the anterior mediastinum.
  • Imaging and subsequent analysis confirmed the mass to be ectopic pancreatic tissue.
  • This presentation deviates significantly from typical cystic or small solid component findings.

Findings:

  • The case represents a rare occurrence of a large, solid ectopic pancreas in the anterior mediastinum.
Keywords:

  • Histopathological examination confirmed pancreatic tissue in the mediastinal mass.
  • This finding expands the spectrum of mediastinal pancreatic ectopia presentations.

    • Implications:

    • This case broadens the differential diagnosis for anterior mediastinal masses in young individuals.
    • It underscores the importance of considering ectopic pancreas in mediastinal lesions, even with atypical morphology.
    • Further investigation into the embryological basis of such presentations may be warranted.
