| Summary: | A 70-year-old woman was referred to our hospital with gross hematuria and diagnosed with right invasive ureteral cancer and bladder urothelial carcinoma in situ. Intravesical BCG therapy and neoadjuvant chemotherapy with carboplatin and gemcitabine were performed at the same time. Subsequently, laparoscopic right nephroureterectomy was performed. Urothelial carcinoma in situ persisted; however, most of the tumor was clear cell carcinoma. The clear cell carcinoma lesion had clear cytoplasm with round nuclei and visible nucleoli in an insular arrangement as is the case with clear cell renal cell carcinoma. No transitional lesion between clear cell adenocarcinoma and urothelial carcinoma was presented. The clear cell carcinoma lesion was GATA3 negative and HNF4α positive; however, the urothelial cancer lesion was GATA3 positive and HNF4α negative. Clear cell carcinoma was diagnosed as clear cell adenocarcinoma similar to clear cell renal cell carcinoma histology. |
