The differential broadens. EUS FNA appearance and cytological findings of pancreatic angiomyolipoma.

CONTEXT Angiomyolipoma is a rare tumor characterized histologically by a mixture of spindle cells, adipose tissue, epithelioid cells, and vascular tissue. It usually involves the kidney followed by the liver whereby the majority of affected patients are female, and many cases arise in the setting of tuberous sclerosis. CASE REPORT We report a case of a 33-year-old female with an asymptomatic incidental right renal mass suggestive of an angiomyolipoma in conjunction with numerous pancreatic masses. CONCLUSIONS The utility of EUS in the differential diagnosis of pancreatic tumors is well established. This is the first known reported EUS detection and FNA confirmation of angiomyolipoma metastatic to the pancreas and should now be added to the already broad differential of metastatic pancreatic tumors.
