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 hemorrhage. [9]
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. Serial abdominal imaging should be performed to assess AML size at 6- to 12-month intervals, at ...
One condition called Wunderlich syndrome is spontaneous, nontraumatic kidney bleeding confined to the subcapsular and perirenal space. It may be the first manifestation of a renal angiomyolipoma (AML), or the rupture of a renal artery or intraparenchymal aneurysm. [2]
Lipomas are rarely life-threatening, and the common subcutaneous lipomas are not a serious condition. Lipomas growing in internal organs can be more dangerous; for example, lipomas in the gastrointestinal tract can cause bleeding, ulceration, and painful obstructions (so-called "malignant by location", despite being a benign growth histologically).
angiomyolipoma, clear-cell "sugar" tumour (CCST), lymphangioleiomyomatosis, and, clear-cell myomelanocytic tumour of ligamentum teres/falciform ligament. abdominopelvic sarcoma of perivascular epitheloid cells [2] primary extrapulmonary "sugar" tumour [2] Thus, it has been advocated that the above could be classified PEComas.

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.
Myelolipoma (myelo-, from the Ancient Greek μυελός 'marrow'; lipo, 'of, or pertaining to, fat'; -oma 'tumor or mass'; also myolipoma) is a benign tumor-like lesion composed of mature adipose (fat) tissue and haematopoietic (blood-forming) elements in various proportions.
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.
