Abstract
Inverted Papillomas Of Urothelium- Inverted papillomas are rare lesions of urothelium characterized by inward proliferation of normal urothelium into the lamina propria. The lesions are usually found in the bladder and the upper urinary tract is rarely involved. These lesions are characteristically formed by invaginated epithelial cords and often misdiagnosed as low grade transitional cell carcinoma. Four cases diagnosed in a ten-year period are reported here. The lesions were in the bladder in 3 patients and localised in the mid-ureter in the ramaining case. The reported coexistence with low-grade transitional cell carcinoma elsewhere in the urinary tract and existence of transitional cell carcinoma on the surface of the inverted papilloma indicate that regular follow-up is mandatory for these patients.
Özet
Invertedpapillomlar gehelde mesanede izlenen, seyrek olarak ust iiriner sistemde rastlanan, normal goriinumlu urotelyumun lamina propria icine proliferasyonu ile meydana gelen ender Iezyoniardir. Bu Iezyoniar karakteristik olarak invajine olan epitelyal kordonlan igerir ve siklikla du§uk dereceli degisici epitel hucreli karsinom ile kanstirilir. Burada, on yilhk bir donem iginde hastanemiz kayitlannda rastlanan 4 olgu aktanlmistir. Lezyonlar olgularm 3'unde mesaneye, digerinde ise orta uretere lokalizedir. Urotelyumda herhangi bir yerde dusuk dereceli bir tranzisyonel hucreli karsinomla birlikte olma olasihgi veya yiizeylerinde dusuk dereceli bir tranzisyonel hucreli karsinom buiunabilecegi seklindeki yayinlar nedeniyle, bu olgularm duzenli izlemleri yapilmahdir.
