The inverted papilloma is a rare urothelial tumor, and its localization at the prosthatic urethra is also exceptional. We present a case of inverted papilloma of the prostatic urethra in a 72 years-old male, with symptoms of urinary flow obstruction. The diagnose is obtained after urethrocistoscopy and transurethral resection at the same time. We discuss about the etiology, clinical presentation, diagnose and treatment of this rare tumor, making special attention to its malignancy ability. 相似文献

Urothelial inverted papilloma is usually a solitary lesion with rare recurrences. Its behaviour is unclear, its potential for recurrence or progression is not well-known. We present a case of inverted papilloma of the bladder with recurrence in prostatic urethra after four years of follow-up. We review etiology, clinical presentation, diagnose, treatment and the present discussion about its malignancy ability. 相似文献

Two cases of inverted papilloma of the urinary bladder are reported. The patients were a 39-year-old male with macrohematuria and a 36-year-old female with interrupted urination. In both of the patients, tumors were resected transurethrally, and histologic examination revealed them to be typical inverted papilloma. 相似文献

Inverted papillomas of the genitourinary tract are uncommon benign neoplasms usually occurring in the urinary bladder and less frequently in the upper urinary tract. To date, there are scant data and no comprehensive studies of inverted papilloma originating in the prostatic urethra. We identified 21 cases and evaluated their demographic, clinical, and histopathologic features. Patients had a mean age of 65.1 years (range: 30 to 89 y), with 10/21 (47.6%) presenting with gross hematuria (n = 8) or irritative symptoms (n = 2) related to the inverted papilloma and 11/21 (52.4%) detected incidentally during work-up/treatment of prostate cancer (n = 6) or benign prostatic hypertrophy (BPH) (n = 5). Fourteen cystoscopically evaluated lesions measured 0.1 to 2.0 cm, and were described as polypoid (n = 9), papillary (n = 4), or an enlarged median lobe (n = 1). Lesions were diagnosed on transurethral resection (n = 8), biopsy/polypectomy targeted to the lesion (n = 6), radical prostatectomy for prostate cancer (n = 4), or biopsy unrelated to the lesion (n = 3). Histologically, 14/21 cases (67%) displayed classic inverted papilloma architecture. The remaining cases showed foci of squamous metaplasia with moderate atypia (n = 4), rare true papillary fronds in a classic inverted papilloma background (n = 2), or both (n = 1). Eleven cases with prostatic tissue revealed adenocarcinoma of the prostate [n = 6; Gleason score 6 (n = 3) or 7 (n = 3)], high-grade prostatic intraepithelial neoplasia (n = 1), benign prostatic hypertrophy (n = 3), or adenosis (n = 1). No patients had a prior history of either inverted papilloma or urothelial carcinoma, whereas 2 patients were diagnosed with high-grade urothelial carcinoma of the bladder synchronous with their inverted papilloma diagnosis. Only 1 of the 18 patients with available follow-up had a recurrence of inverted papilloma in the prostatic urethra. None of the other patients had local recurrences or recurrences at other locations in the urinary tract (mean follow-up 39.9 mo; range: 3 to 120 mo). Inverted papillomas of the prostatic urethra are benign lesions that are commonly detected incidentally and are not associated with a history of urothelial malignancy. Although urothelial carcinoma elsewhere in the genitourinary tract may occur simultaneously, malignant transformation or recurrence as a malignant lesion has not been identified in inverted papilloma of the prostatic urethra. 相似文献

We report 2 cases of inverted urothelial papilloma of the ureter. The second case demonstrates inverted papilloma and papillary transitional cell carcinoma in a single polypoid lesion. Conservative therapy was performed and a follow-up 12 months later shows no evidence of recurrences. 相似文献

目的 探讨膀胱内翻性乳头状瘤(IPB)的临床表现、临床诊治方案,提高对IPB的诊疗水平.方法 回顾总结本院2011年1月~ 2013年12月收治的具有完整临床及随访结果的37例IPB的资料.结果 37例术后病理均明确为内翻性乳头状瘤,其中2例并发低级别尿路上皮癌,3例伴有炎症改变.术后随访时间为10 ~34个月(平均28个月),随访期内其中36例未见复发,1例于术后第15个月复发,再行TUR-BT术,病理提示低级别尿路上皮癌.结论 IPB是一种少见的良性肿瘤,外科手术(TUR-BT)是主要治疗方法.因IPB有复发性、且与尿路上皮癌(TCC)伴生或进展为TCC,故术后定期膀胱灌注、膀胱镜检查是极其重要的. 相似文献

Papillary adenoma of the prostatic urethra: Report of two cases 总被引:1,自引:0,他引:1
MUSTAFA ÖZGÜR TAN YAKUP KORDAN NUR DENZ ÖZLEM ERDEM LKER EN BRAHM BOZKIRLI 《International journal of urology》2003,10(8):459-462
Papillary adenoma of the prostatic urethra is a rare cause of hematuria, hemospermia and lower urinary tract obstruction, especially in young adults. We report two cases of papillary adenoma and their endoscopic views. One of the patients had a lesion located on the verumontanum and presented with hematuria, hemospermia and symptoms of lower urinary tract obstruction. The other patient had papillary lesions located in the paramontanal gutter and presented with persistent painless hematuria. The origin of both lesions was proven to be prostatic epithelial differentiation using immunohistochemical identification of prostate-specific antigen. Papillary adenoma is believed to be benign, therefore, both lesions were carefully excised and fulgurated transurethrally. 相似文献

Congenital polyp of the prostatic urethra: report on 2 cases 总被引:1,自引:0,他引:1
F Aragona F Di Tonno G Tuccitto A Fandella F Zattoni R De Caro P F Munari G Passerini Glazel 《Urologia internationalis》1988,43(2):113-117
Congenital polyps of the prostatic urethra are an uncommon cause of obstructive uropathy, infection and/or hematuria in male children. A filling defect localized in the posterior urethra on the voiding cystourethrogram represents the peculiar diagnostic finding. Transurethral resection is the treatment of choice, according to the size of the polyp. Two cases of congenital posterior urethral polyps are reported and the main clinical and radiological features are discussed. This lesion has to be considered in the differential diagnosis of the voiding dysfunction in young boys. 相似文献

A 59-year-old male with a complaint of gross hematuria was found to have a pedunculated and non-papillary tumor on the prostatic urethra. The tumor was resected transurethrally. The pathological finding was inverted papilloma. Although the majority of the cases of inverted papilloma have been found in the bladder, we reported the 32nd case located on the prostatic urethra in Japan. 相似文献

Inverted papilloma of the renal pelvis: report of a case 总被引:1,自引:0,他引:1
Inverted papilloma of the upper urinary tract is a rare lesion. To our knowledge, we report here the 32nd case of inverted papilloma of the renal pelvis. A 50-year-old man presented with asymptomatic gross hematria. Excretory urography showed a filling defect in the left upper calyx. Computerized tomography showed a poorly enhanced low-density area within the renal pelvis. Since radiographic findings suggested a renal pelvic tumor, the patient underwent total nephroureterectomy. Unexpectedly, a 3 x 2.5 cm polypoid tumor of the renal pelvis was consistent with inverted papilloma. Since this benign lesion is extremely rare within the upper tract and its radiographic characteristics closely resemble those of urothelial carcinoma, the preoperative diagnosis of inverted papilloma of the upper tract cannot be conclusively established even by modern imaging techniques. Therefore treatment consistent with that for urothelial carcinoma should be applied in this disease entity. 相似文献
