Treatment should be considered for asymptomatic, growing AMLs measuring larger than 3 cm in diameter. [1] Angiomyolipomas do not normally require surgery unless life-threatening bleeding is present. [6] Some centers may perform preventative selective embolisation of the angiomyolipoma if it is more than 4 cm in diameter, due to the risk of ...
Treatment of renal angiomyolipoma [ edit ] Renal angiomyolipomas (AMLs) may require embolization or cauterization for control of bleeding, a complication that is thought to be more common when tumor diameter exceeds 4 cm. [ 119 ] The extent of aneurysmal change may determine bleeding risk.
Angiolipoma is a subcutaneous nodule with vascular structure, having all other features of a typical lipoma.They are commonly painful. [1]: 624 [2] Angiolipomas manifest as multiple painful subcutaneous nodules commonly on the upper limbs.
Angioleiomyoma (vascular leiomyoma, angiomyoma) of the skin is thought to arise from vascular smooth muscle, and is generally acquired. [3] Angioleiomyomas appear as small (<2 cm), firm, movable, slow growing subcutaneous nodules.
Treatment is typically by observation or surgical removal. [1] Rarely, the condition may recur following removal, but this can generally be managed with repeat surgery. [1] They are not generally associated with a future risk of cancer. [1] Lipomas have a prevalence of roughly 2 out of every 100 people. [2]
Robotic-assisted partial nephrectomy has been proposed as a surgical treatment of a ruptured angiomyolipoma causing retroperitoneal hemorrhage, combining the advantages of a kidney preservation procedure and the benefits of a minimally invasive procedure without compromising the safety of the patient.

Although it is a benign tumour and does not invade neighbouring tissues, it has a tendency to recur after surgical excision so it is termed "aggressive". Recurrence can occur as early as six months from initial resection.
Post-operatively, the presence of renin granules in pathology specimens as well as immunohistochemical analyses could help differentiating this tumor from other primary renal tumors such as hemangiopericytoma, glomus tumor, metanephric adenoma, epithelioid angiomyolipoma, Wilms tumor, solitary fibrous tumor, and some epithelial neoplasms.
