Summary

Extra-adrenal myelolipomas are rare benign tumors. This case highlights a perirenal extra-adrenal myelolipoma discovered during surgery in a patient with von Hippel-Lindau disease, posing a diagnostic challenge.

Area of Science:

  • Urologic oncology
  • Surgical pathology

Background:

  • Extra-adrenal myelolipomas are rare, benign tumors originating outside the adrenal gland.
  • These tumors consist of hematopoietic and adipose tissues and are typically asymptomatic.

Observation:

  • A perirenal extra-adrenal myelolipoma was incidentally discovered during an intraoperative procedure.
  • The patient had a known diagnosis of von Hippel-Lindau disease and was undergoing a partial nephrectomy.

Findings:

  • The intraoperative finding of a perirenal extra-adrenal myelolipoma presented a diagnostic dilemma for the urologic surgeon.
  • The tumor's benign nature was confirmed, despite its unusual location and incidental discovery.

Implications:

  • This case underscores the importance of considering rare diagnoses in surgical settings, especially in patients with underlying genetic conditions.
  • Accurate intraoperative identification and management of unexpected findings like extra-adrenal myelolipomas are crucial for patient outcomes.
