We reported a case of inverted papilloma of the bladder, and six cases (two of ureteral cancer and four of bladder cancer) of transitional cell carcinoma with inverted proliferation. These tumors were superficial and pedunculated as well as transitional papilloma or ordinary papillary transitional cell carcinoma though they showed a non-papillary and polyp-like configuration. Moreover, these urothelial cancers with inverted proliferation were thought to be similar to papillary cancer with regard to grading, multiplicity, invasiveness and recurrence. Therefore, transurethral resection or segmental ureterectomy may be recommended for the tumor of low grade malignancy and radical treatment including systemic chemotherapy may be recommended for the tumor of high grade malignancy.
我们报告了1例膀胱内翻性乳头状瘤，以及6例具有内翻性增殖的移行细胞癌（2例输尿管癌和4例膀胱癌）。这些肿瘤虽然呈现非乳头状和息肉样形态，但与移行性乳头状瘤或普通乳头状移行细胞癌一样，为浅表性且有蒂。此外，这些具有内翻性增殖的尿路上皮癌在分级、多灶性、侵袭性和复发方面被认为与乳头状癌相似。因此，对于低级别恶性肿瘤，可建议行经尿道切除术或节段性输尿管切除术；对于高级别恶性肿瘤，可建议包括全身化疗在内的根治性治疗。
