“…The most common histologic types are adenocarcinoma and urothelial carcinoma ( 12 ). The incidence of VAs after cystoplasty is very low and most of them develop in the neobladder or anastomosis line ( 24 ). To our knowledge, only 2 cases of VAs originating from the native bladder mucosa have been reported ( 4 , 12 ).…”

“…In the ureters, tumor growth with mucus retention may be the main cause of ureteral obstruction, and total excision of the tumor prevents early obstruction ( 29 ). In patients with bladder augmentation, long-term active surveillance is necessary in terms of neoplasia development ( 12 , 24 ). In our presented case, the urethral tumor was excised.…”

Villous adenomas (VAs) in the female urethra are rare with only seven cases in the English literature to our knowledge. In patients with bladder augmentation cystoplasty, the neoplasia development risk increases and most of these develop in the neobladder or anastomosis line. Only two cases of VA developing from the native bladder mucosa have been reported. Physical examination of a 76-year-old female who had a history of augmentation cystoplasty revealed a caruncula-like structure protruding from the urethral meatus. The urinary USG showed that the lesion had no relation with the bladder. The lesion was excised. Microscopically, it consisted of villous structures covered with pseudostratified intestinal type epithelium. Low-grade dysplasia was present in the epithelium but high-grade dysplasia or in-situ/invasive carcinoma was not observed. Immunohistochemical study showed positivity for CK7, CK20, EMA, CEA and CDX2. The case was reported as VA of the urethra. We presented the first VA case arising in the urethra of a female patient with intestinal bladder augmentation. Excision is curative for pure VAs. Transformation to carcinoma or recurrence has not been reported. However, in one third of the cases, a malignant tumor may accompany the lesion. Therefore, all excision material should be examined carefully. Routine endoscopic follow-up should be performed in cases with bladder augmentation.

“…6,7 Even rarer is their occurrence in a setting of augmentation cystoplasty. 8,9 We present here a unique case of multifocal recurrent villous adenoma involving native bladder mucosa of an augmented bladder, bilateral ureters, and renal pelvis, with coexistent foci of adenocarcinoma and neuroendocrine carcinoma, in a patient with history of augmentation colocystoplasty. We additionally discuss the pathogenesis of development of carcinoma in the setting of augmentation cystoplasty.…”

Villous adenomas arising in the bladder following augmentation cystoplasty procedures are exceedingly rare. Even rarer is their occurrence in the native bladder mucosa and the upper urinary tract. In this article, we present a unique case of multifocal recurrent villous adenoma involving native bladder mucosa of an augmented bladder, bilateral ureters, and renal pelvis, with coexistent foci of adenocarcinoma and neuroendocrine carcinoma, in a patient with history of augmentation colocystoplasty. We additionally discuss the pathogenesis of development of carcinoma in the setting of augmentation cystoplasty.
