Core Tip
Core tip: Perivascular epithelioid cell tumor (PEComa) of the pancreas is an unusual tumor deriving from mesenchyma. Via describing a rare case of pancreatic PEComa, we highlight the clinicopathological features of PEComa and conduct a literature review focusing on this tumor type so as to deepen the understanding of the subject. We also reviewed the biological behavior, prognosis, and therapeutic strategy of PEComa.
