Summary
Extra-adrenal myelolipomas, benign tumors of hematopoietic and fatty tissue, are rare but important to recognize. Awareness is crucial for differential diagnosis of retroperitoneal tumors to avoid confusion with malignant neoplasms.
Area of Science:
- Oncology
- Pathology
- Radiology
Background:
- Myelolipomas are benign tumors typically found in the adrenal glands.
- Extra-adrenal myelolipomas are rare, with only 37 cases reported.
- Presacral location accounts for over half of reported extra-adrenal cases.
Observation:
- This report highlights the diagnostic challenge posed by presacral myelolipomas.
- These tumors can be mistaken for more common and aggressive retroperitoneal malignancies.
- Specific radiographic and histologic features differentiate myelolipomas from invasive cancers.
Findings:
- A case of extra-adrenal myelolipoma is presented.
- Literature review of extra-adrenal myelolipoma cases is provided.
- Radiographic and histologic distinctions are discussed.
Implications:
- Increased awareness of extra-adrenal myelolipomas is needed for accurate diagnosis.
- Distinguishing these benign tumors from malignant neoplasms is critical for patient management.
- This case contributes to the understanding of rare retroperitoneal tumor presentations.
