Squamous cell carcinoma (SCC) rarely accounts for 2-5% of urinary bladder cancer. Chronic irritation of the bladder from infection or indwelling catheter is a risk factor for SCC. Only a handful of cases of suprapubic cystostomy (SPC) site SCC have been reported and have been always seen in paraplegics or urethral stricture requiring long-standing catheterization. We report a case of a 69-year-old male with an indwelling (SPC) of 25 years duration for a urethral stricture who presented with a fungating growth around the SPC site enveloping the catheter confirmed to be squamous cell carcinoma. Imaging revealed involvement of abdominal wall and urinary bladder with no metastatic spread. He underwent wide local excision (WLE) of the lesion with radical cystectomy and ileal conduit reconstruction with bilateral ilio-inguinal lymphadenectomy and pedicled anterolateral thigh flap for abdominal wall reconstruction. He received adjuvant radiotherapy and was found to be recurrence free at 3 months. Among the cases previously reported, 9 of the 12 cases were treated surgically with 4 of those combined with partial cystectomy and 4 with radical cystectomy. SPC site SCC tends to be localized around the catheter and into the abdominal tract and wide surgical excision offers the best hope for cure. Regular cystoscopy and biopsy from bladder around the catheter site can help early detection and the treatment should be personalized to each patient.
鳞状细胞癌(SCC)在膀胱癌中占比很少,仅为2%至5%。感染或留置导尿管对膀胱的慢性刺激是SCC的一个危险因素。耻骨上膀胱造瘘术(SPC)部位发生SCC的病例仅有少数报道,且多见于截瘫患者或需要长期导尿的尿道狭窄患者。我们报告一例69岁男性,因尿道狭窄行SPC已25年,其SPC部位出现包绕导尿管的蕈状肿物,经确诊为鳞状细胞癌。影像学检查显示腹壁和膀胱受累,但无转移扩散。他接受了病变的广泛局部切除(WLE),同时行根治性膀胱切除术和回肠导管重建术,并进行双侧髂腹股沟淋巴结清扫及带蒂股前外侧皮瓣腹壁重建术。他接受了辅助放疗,3个月时未发现复发。在先前报道的病例中,12例中有9例接受了手术治疗,其中4例联合部分膀胱切除术,4例接受根治性膀胱切除术。SPC部位SCC往往局限于导尿管周围并累及腹腔,广泛手术切除是治愈的最大希望。定期膀胱镜检查及对导尿管周围膀胱组织进行活检有助于早期发现,治疗应根据每位患者的情况个体化制定。
