Angiomyolipomas （AMLs） located in the adrenal region are exceptionally rare. The preoperative diagnosis of AMLs is difficult.
We report our experience with a 68-year-old woman who presented with right-sided back pain. A computed tomography scan showed a 66×45 mm fatty adrenal mass. Hormonal function was within normal limit. Laparoscopic adrenalectomy was performed. Because bleeding occurred from the tumor surface, we decided on an open conversion and removed the tumor together with a part of the normal adrenal gland. The histopathological features confirmed the diagnosis of AML in the adrenal region. The patient made an uneventful recovery and was discharged one week following the operation.
When we perform laparoscopic adrenalectomy for a fatty adrenal tumor, we must handle the tumor considering the possibility of an AML. Additionally, to reduce excessive bleeding, we must use an open conversion in cases of uncontrollable bleeding.
