Why the study?
Extra-adrenal myelolipomas are rare benign tumours that can be morphologically similar to other soft tissue tumours, making diagnosis challenging.
Case Report (n=1)
Simultaneous adrenal and extra-adrenal myelolipomas are rare but should be considered in the differential diagnosis of retroperitoneal fat-containing tumors.

Supports including myelolipoma in the differential for retroperitoneal fat-containing tumors; leaves open need for larger series to guide practice.
BACKGROUND: Extra-adrenal myelolipomas are rare benign tumours. Other soft tissue tumours such as well-differentiated liposarcomas appear morphological almost identical. Preoperative imaging and especially biopsy are important tools to diagnose these lesions. CASE PRESENTATION: We report a very seldom case of a simultaneous myelolipoma of the adrenal gland in association with an extra-adrenal myelolipoma in an 75-year-old man. With a review of the literature we describe and discuss the aetiology, differential diagnosis and treatment of patients with respect to adrenal and extra-adrenal lesions. CONCLUSION: The appearance of a simultaneous adrenal and extra-adrenal myelolipoma is a rare incident. We conclude that such lesions should be considered in the differential diagnosis of a fat-containing tumour in the retroperitoneal tissue/compartment.

Zieker et al. (2008) conducted a case report in Simultaneous adrenal and extra-adrenal myelolipoma (n=1). Surgical resection (adrenalectomy and removal of infrarenal mass) was evaluated on Diagnosis and treatment outcome.
