Perinephric myxoid pseudotumor of fat – histopathological and molecular characterization of 3 cases after renal transplantation
PMPF is a rare benign condition typically associated with chronic kidney disease, occurring late in the course. The radiological findings may be mistaken for those of a malignant tumor, and histopathological examination is required to exclude a malignant neoplasm, in particular a well-differentiated or dedifferentiated liposarcoma of the retroperitoneum. Renal transplant recipients can be affected by PMPF, which can occur in both native and transplanted kidneys several years following renal transplantation.
