Abstract

|
A common soft-tissue tumor, malignant fibrous histiocytoma (MFH) occurs in mainly limbs, retroperitoneal and peritoneal space, and occurrence in kidneys or the ureter is very rare. Dioctophyma renale (D. renale) since first discovered in dog’s kidney was found in the kidneys of animals such as mink, coyote and weasel, and human infection has only been reported in only approximately 20 cases worldwide. MFH of the ureter and D. renale infection very rarely occur in humans, and has not been reported in our country. Here, we described the case of an adult man in whom MFH of the ureter simultaneously occurred with D. renale infection. An initial CT scan showed a well-defined, persistent, enhancing polypoid mass-like lesion in the upper ureter. After 10 months, D. renale was excreted in the urine and a follow-up CT scan showed an increase in the size of that lesion and irregular thickening of the ureter wall. The diagnosis of MFH was pathologically verified.
