Fatty angiomyolipoma

Angiomyolipomas are tumours consisting of perivascular epithelioid cells (cells which are found surrounding blood vessels and which resemble epithelial cells). A tumour of this kind is known as a PEComa, from the initials of perivascular epithelioid cell.

Twenty percent of AMLs occur in patients with tuberous sclerosis,65 while the remaining 80% occur sporadically.
