Abstract

|
Extraskeletal osteoclast-like giant cell (OGC) tumors are uncommon and have mainly been found in the breast and pancreas. OGC neoplasms of the urinary tract are extremely rare. Most cases found in the renal pelvis and bladder are associated with either an in situ urothelial malignancy or a conventional high-grade urothelial carcinoma. These malignancies tend to be associated with a poor prognosis and disease course. To our knowledge, no cases of OGC tumors of the distal ureter only have been published. Here, we present the case of a 76-year-old man who underwent hand-assisted laparoscopic nephroureterectomy because of painless gross hematuria with right flank pain. Pathologic examination showed OGC carcinoma of the right distal ureter. No local tumor recurrence or distant metastasis was found at the 5-month follow-up.
