Primary signet-ring cell carcinoma of the urinary bladder: a case report

We report a case of signet-ring cell carcinoma of the urinary bladder. A 48-year-old female was hospitalized because of general fatigue, pollakiuria and residual sensation. Renal ultrasonography disclosed bilateral hydronephrosis. The serum level of cretinine was 3.1 mg/dl, and we diagnosed the patient with post-renal failure. Cystoscopic examinations revealed non-papillary sessile tumors in the trigone. Histopathological findings of the biopsy specimen demonstrated signet-ring cell carcinoma. There was no evidence indicating bladder metastasis from the cancer in other organs. The patient died of cachexia 5 months after the diagnosis. She was autopsied, and the diagnosis of signet-ring cell carcinoma of the urinary bladder with metastases in various organs was confirmed. This disease is extremely rare and has a poor prognosis. We review the previous cases reported in the literature.     

Signet-ring cell carcinoma involving the urinary bladder. Report of a case and review of 21 cases

A case of signet-ring cell carcinoma involving the urinary bladder, which is a rare variant of adenocarcinoma, is presented. 21 cases have so far been reported in the occidental and Japanese journals. In 13 patients (62%) the carcinomas were of urachal origin and 8 (38%) of bladder origin. The prognosis of signet-ring cell carcinoma originating in bladder is poorer compared to that in urachus; 2-year survival of 40% for the bladder cancer group and 70% for the urachus. A radical cystectomy with excision of adjacent tissues, which might improve the prognosis in this fatal malignancy, should be considered.

Apparently bladder origin signet ring cell carcinoma: a case report

A 72-year-old woman with signet-ring cell carcinoma of the urinary bladder treated with total cystectomy is described. The bladder yielded linitis plastica pattern of infiltration similar to that seen in the gastric cancer, i.e., cancer tissue extended almost whole bladder deeply to the serosa, whilst the mucosal surface was only minimally invaded. She received no adjuvant therapy and she is alive without recurrence 8 months after the operation. We review the reported cases and shortly discuss the prognosis and treatment of primary signet-ring cell carcinoma of the urinary bladder.     

A case of small cell carcinoma in a diverticulum of the bladder

We report a case of small cell carcinoma in a diverticulum of the bladder. A 64-year-old Japanese man visited our hospital with the chief complaint of urinary retention. Cystoscopy revealed a papillary tumor arising in a diverticulum on the right lateral wall of the bladder. Partial cystectomy was performed under the diagnosis of bladder cancer in the diverticulum. The histopathological diagnosis was a combination of small cell carcinoma and urothelial carcinoma, of which the former was dominant. It is often difficult to detect tumors in the bladder diverticula and its early penetration is not rare because of the thin wall. Therefore, the prognosis of the bladder cancer in the diverticulum is believed to be generally poor. On the other hand, small cell carcinoma originating in the urinary bladder is also characterized by its extreme rareness and poor prognosis. To our knowledge, this is the second case report of the small cell carcinoma arising in a diverticulum of the urinary bladder in the Japanese literature.     

Primary signet-ring cell carcinoma of urinary bladder

The tenth reported case of primary signet-ring cell carcinoma of the urinary bladder is described. This adenocarcinoma of varying degrees of differentiation (predominantly, signet-ring cells and, partially, poorly differentiated cells and mucin-secreting columnar cells which were arranged in glandular pattern) involved almost the entire mucosa, invading the inuscularis of bladder wall in places, ejaculating ducts, and prostatic ducts.     

Transitional cell carcinoma of the urinary bladder accompanied by signet-ring cell carcinoma: a case report

A 58-year-old man visited our clinic with complaints of gross hematuria and pollakisuria. Cystoscopic examination revealed multiple non-papillary broad based tumors and reddish unstable mucosa in the bladder. The pathological specimen of the transurethral biopsy of the tumors showed signet-ring cell carcinoma predominantly and adenocarcinoma transforming into signet-ring cell carcinoma partially. A total cystectomy with ileal conduit urinary diversion was performed. The histopathological finding of the radical cystectomy specimen was grade 3 transitional cell carcinoma accompanied by adenocarcinoma. These findings suggest that the adenomatous metaplasia of transitional cell carcinoma in the bladder could differentiate into signet-ring cell carcinoma.     

原发性膀胱印戒细胞癌的诊断和治疗：附2例报告

目的提高对原发性膀胱印戒细胞癌的认识和诊治水平。方法回顾分析我院收治的2例原发性膀胱印戒细胞癌,结合文献就其临床表现、诊断及治疗进行讨论。第1例患者,男,57岁,以全程肉眼血尿和继发的贫血就诊,CT检查示膀胱顶部占位性病变,界限清楚,有斑点状钙化。第2例患者,男,66岁,以黏液尿就诊,无其他临床表现,CT示膀胱右侧壁占位性病变。均于术前膀胱镜活检明确诊断。第1例因患者拒绝膀胱全切除术行膀胱部分切除术加脐尿管和相邻腹膜的切除术,第2例因陈旧性心肌梗塞行膀胱部分切除术。结果第1例患者术后血尿消失,贫血纠正。7个月后发现肺部转移,术后8个月死亡。第2例术后黏液尿和膀胱刺激症状消失。随访37个月,患者恢复良好,无复发和转移。结论原发性膀胱印戒细胞癌临床罕见,预后较差,诊断主要依赖病理学检查,全膀胱切除术是其首选治疗方法。     

Primary signet ring cell carcinoma of bladder

Patients presenting with rare primary signet-ring cell carcinoma of the bladder are often found to be in renal failure and to have distressing symptoms of bladder instability. Their clinical course most often is rapidly fatal, and radical cystectomy with urinary diversion offers the only hope of increasing longevity. We herein review the literature of this rare variant of bladder adenocarcinoma and present a case in which a unique form of urinary diversion reversed the uremic state and increased this patient's longevity.

Signet-ring cell adenocarcinoma involving the bladder and the rectum. Apropos of two cases]

Two cases of primary signet-ring cell carcinoma involving the urinary bladder, with invasion of the rectum, are presented. Pelvic exenterations were performed, followed by a rapidly fatal outcome (6 and 7.5 months). These cases of signet-ring cell carcinoma of the bladder were reviewed with 33 previously reported cases in the literature. The clinical characteristics, histologic findings, pathogenesis, and effectiveness of aggressive treatment of this rare bladder malignancy are discussed.     

Signet-ring cell carcinoma of the urinary bladder associated with transitional cell carcinoma of the right ureter

We report on a case of a 72-year-old male with vesical signet-ring cell carcinoma containing a transitional cell carcinoma (TCC) component. It was associated with pure TCC of the right ureter. No other microscopic changes were found in the bladder. The pathogenesis of this signet-ring cell carcinoma is described.     

Primary signet-ring cell carcinoma of urinary bladder

A case of primary signet-ring cell carcinoma of the urinary bladder is described clinically and pathologically. In this rare neoplasm the characteristic cells contain large amounts of cytoplasmic mucin which compresses the nucleus to one side. This tumor demonstrates nicely the ability of bladder epithelium to undergo metaplasia. Most previously described cases have pursued a relentlessly progressive and fatal course despite varied forms of therapy.     

A case of signet-ring cell carcinoma of the urinary bladder

Signet-ring cell carcinoma of the urinary bladder is a rare disease. A 78-year-old man was admitted to our hospital on March 18, 1988 with the complaints of microhematuria and pollakisuria. Cystoscopic examination revealed non-papillary tumor at the dome of the bladder. partial cystectomy was done under epidural anesthesia. Pathological findings revealed signet-ring cell carcinoma. The gastrointestinal, respiratory and genitourinary tracts were examined but no other tumor lesions could be found. The postoperative course was uneventful, and chemotherapy such as biological response modifier was administered. However, the patient died of heart failure on July 14, 1988. This is the sixtieth case reported in the literature.     

膀胱肉瘤样癌与癌肉瘤

目的探讨膀胱肉瘤样癌及膀胱癌肉瘤组织学特性。提高对膀胱肉瘤样癌和膀胱癌肉瘤的病理学和临床特征的认识。方法报告1例膀胱肉瘤样癌和1例膀胱癌肉瘤的病例资料。2例均为男性。年龄分别为60岁、66岁。1例以肉眼血尿就诊,膀胱镜、CT和B超检查均诊断为膀胱肿瘤,肿瘤呈侵润性生长,术前活检提示为移行上皮细胞癌。行膀胱部分切除术,术后行全身化疗和膀胱灌注化疗;病理检查为癌肉瘤。另1例以膀胱血块填塞就诊,急诊手术行血块清除、止血及肿瘤姑息性切除,术后均行全身化疗和膀胱灌注化疗,术后病理检查为肉瘤样癌。结果1例行膀胱部分切除者,术后病理可见上皮和肉瘤样间质2种恶性成分,且可见到横纹肌肉瘤成分,诊断为膀胱癌肉瘤,3个月后复查局部肿瘤复发。行膀胱全切-回肠新膀胱术,目前仍在随访中。另1例术后病理可见上皮和肉瘤样间质2种恶性成分,癌与肉瘤样区有移行,诊断为膀胱肉瘤样癌,1个月后死于全身衰竭、多处转移。结论膀胱肉瘤样癌和癌肉瘤具有浸润性生长的生物学特性,恶性程度高,预后不良;化疗、放疗都不太敏感,手术仍是首选治疗方式。     

Renal cell carcinoma with solitary metachronous metastasis to the urinary bladder

We report a case of renal cell carcinoma with solitary metachronous metastasis to the urinary bladder occurring 6 years after radical nephrectomy. The patient was treated with partial cystectomy and survived for 60 months. Other cases like this one were reviewed in published reports, and the 3-year survival rate for patients with this type of cancer with solitary metastasis to the urinary bladder was found to be 80%. The follow-up duration of our case was the longest in the published studies. We suggest that urinary bladder metastasis of renal cell carcinoma should be resected because no effective treatment for metastatic renal cell carcinoma is available. A good prognosis may be expected, especially in patients with solitary metastasis to the urinary bladder.     

膀胱腺癌的诊断和治疗(附29例报告)

A case of synchronous ipsilateral renal cell carcinoma and transitional cell carcinoma]

A case of synchronous ipsilateral renal cell carcinoma with renal pelvic and ureteral transitional cell carcinoma is reported. A 80-year-old man, who had had transurethral resection of bladder tumor three times, was admitted on August, 1989 for recurrence of bladder tumor. Excretory pyelography revealed a filling defect of left renal pelvis. Findings of retrograde pyelography and computed tomography were in accord with those of the excretory urograms. Under a diagnosis of the left renal pelvic and ureteral tumor associated with the bladder tumor, left nephroureterectomy with bladder cuff resection was performed. Pathological diagnosis was renal pelvic and ureteral transitional cell carcinoma with renal cell carcinoma, which existed incidentally in the same kidney. Double unrelated primary carcinoma in urinary tract, especially, double dissimilar primary carcinoma in the same kidney, is rare. To our knowledge, this case is the 20th double cancer in upper urinary tract reported in Japan.     

Signet-ring cell carcinoma of the bladder and the prostate. Report of 4 cases

During a 9-year period in our clinic 4 patients were seen with signet-ring cell carcinoma. 2 patients had primary signet-ring cell carcinoma of the bladder, 1 of the prostate. In the 4th case the tumor was located near the penoscrotal angle of the urethra. These cases are reviewed and their main characteristics, mentioned in the literature, are discussed briefly.
