A 70-year-old female with inverted @entity1698 is presented. She was hospitalized because of asymptomatic macrohematuria. Excretory urography and retrograde pyelography demonstrated a filling defect with smooth contour at the mid-portion of the right ureter. Abdominal computer tomographic (CT) scan showed @entity66 (CT number 41) at the same portion as the filling defect. She was diagnosed as having an @entity5 and right nephroureterectomy was performed. The gross specimen contained a 24 X 12 mm, polypoid, pedunculated and smooth-surfaced @entity5 . Pathological diagnosis was @entity1179 . However, microscopic examination revealed a malignant finding corresponding to transitional cell @entity189 grade 1.
