Core Tip

Core Tip: Primary extra-pancreatic pancreatic-type acinar cell carcinoma (ACC) is a rare malignant tumor, with very few reported cases. Extra-pancreatic pancreatic-type ACC arising in the perinephric space has not been reported. The imaging characteristics of our case included an oval shape, relatively homogenous density or signal, a hypervascular pattern and rapid washout with enhancement, and an enhanced capsule. This report of diagnosis and treatment of this rare tumor. will be helpful for clinicians, radiologists and pathologists to differentiate this unusual tumor from other plausible retroperitoneal neoplasms. The recommended treatment for this tumor is complete surgical resection.
