Abstract
BACKGROUND: Peliosis hepatis is an uncommon vascular condition characterized by multiple, randomly distributed, blood-filled, and cyst-like cavities throughout the liver. The unique clinical nature consisting of an asymptomatic, benign, and incidental finding sometimes conceals itself even until autopsy. However, the exact pathomechanism remains as yet unproven. METHOD: We encountered the patient with multiple hypervascular masses in the whole liver and investigated the clinicopathological features underlying this condition. RESULTS: Detailed herein is a case of peliosis hepatis on the basis of our findings. Our patient illustrated a lethal instance which mimicked a malignancy although it is usually an indolent finding. CONCLUSION: Peliosis hepatis should always be borne in mind as a differential diagnosis of atypical hypervascular hepatic lesion, especially in patients with clinical conditions described in the text.
