Pure primary choriocarcinoma of the urinary bladder with long-term survival

Choriocarcinoma was diagnosed in a 77-year-old woman with an acute massive, painless hematuria. One year after anterior pelvic exenteration and ileal conduit, the beta-human chorionic gonadotropin level increased to 934 mIU/mL without any sign of tumor progression. After six courses of chemotherapy (vincristine, actinomycin, and cyclophosphamide), the beta-human chorionic gonadotropin levels returned to normal. To our knowledge, this is the fourth case of pure choriocarcinoma in the bladder, with the longest survival time of 33 months so far.     

Primary osteosarcoma of the urinary bladder

Primary osteosarcoma of the bladder, together with transitional cell carcinoma, occurred in a 74-year-old female presenting with haematuria and lumbago. She was treated with chemotherapy and radical cystectomy. Though it was conceived to be curative, she died of a recurrence 5 months after the operation. Primary osteosarcoma of the bladder is an unusual and highly malignant disease. In spite of radical therapy, the outcome has been dismal with some exceptions.     

Primary adenocarcinoma of urinary bladder

We reviewed the clinical course and pathologic findings of 17 patients with adenocarcinoma of the urinary bladder at Massachusetts General Hospital between 1962 and 1978. The 12 men and 5 women were between thirty-eight and eighty-six years old (mean, sixty years). Five patients had urachal adenocarcinoma, 8 had pure adenocarcinoma, and 4 had mixed adenocarcinoma and transitional cell carcinoma. Twelve of 17 patients (71 per cent) had muscle invasion (T₂?T₃), and none had evidence of regional or distant metastases at initial presentation. The mean follow-up was four years. The treatment modalities included transurethral resection alone in 3 patients, radical cystectomy in 4, simple cystectomy in 2, salvage radical cystectomy in 1, and partial cystectomy in 7, 3 of whom also received radiation therapy. Over-all crude three and five-year survival rates were 60 per cent and 27 per cent, respectively; patients with invasive disease did poorly regardless of treatment modality. Five of 8 patients who died had evidence of metastatic disease, and only 1 patient with invasive disease was alive more than five years. However, 2 of 3 patients with invasive urachal adenocarcinoma who had preoperative radiotherapy plus partial cystectomy are free of disease at thirty-eight and sixty months.     

Primary choriocarcinoma of the bladder: a case report of autopsy

The patient was a 70-year-old male with complaint of macrohematuria at the first visit to our clinic on June 10, 1986. At that time, cystoscopy revealed a thumb sized papillary tumor and a rice sized non papillary tumor, and the biopsy specimen was pathologically diagnosed as undifferentiated carcinoma. But, he refused admission. On January 30, 1987, he came back to our clinic with complaints of dyspnea, general fatigue and weight loss. Moderate lt. gynecomastia was found and the level of serum hCG-beta was detected as high as 101 ng/ml. Excretory urogram and enhanced CT revealed a large mass in the bladder. In the seventeenth day after admission, he died of lung edema and heart failure. The findings of autopsy showed a large light greenish to light brownish tumor of 10 X 10 X 3 cm in the bladder. Distant metastases were observed in internal, common iliac and paraaortic lymph nodes, but without other distant metastasis. In histological and immunohistochemical studies, the final diagnosis is choriocarcinoma of the bladder, containing syncytiotrophoblastic giant cells with hCG-beta granules as an undifferentiated carcinoma. To our knowledge this case is the eighth described in Japan. Herein we report a new case of primary choriocarcinoma of the bladder and make a brief review of the literatures.     

Primary carcinoid tumor of the urinary bladder

A polyp of about 1.0 cm diameter was incidentally found at the center of theposterior wall of the urinary bladder in a 73-year-old man on cystoscopicexamination. A polyp was resected through a transurethral route withoutrecurrence for 22 months. A polyp consisted of a tumor covered with mucosaof the bladder. Tumor cells have round or oval nuclei with fine chromatinand one or two nucleoli per nucleus, and finely granular eosinophiliccytoplasm, being arranged in a trabecular or tubular pattern. Furthermore,they showed positive staining for chromogranin-A and with Grimelius stain,indicating that the tumor is a carcinoid tumor. Since there was no evidenceof carcinoid tumors in organs other than the urinary bladder, the presentcase is a primary carcinoid tumor (well differentiated endocrine tumor) ofthe urinary bladder which is extremely rare.     

Primary lymphoepithelioma-like carcinoma urinary bladder

ObjectiveTo present a new case of a primary lymphoepithelioma-like carcinoma of the urinary bladder.Material and methodsWe describe the clinical, diagnosis, treatment and development of this kind of tumor. Review of the literature.ConclusionsIt is an unusual type of bladder cancer that requires a carefully analyse from the pathologist and a confirmation by means of immunohistochemistry techniques. The focal form is associated with poor prognosis. Radical cystectomy is the gold standard. This kind of tumor has sensibility to chemo and radiotherapy, who can be used as adyuvant therapy.     

Primary malignant lymphoma of urinary bladder

A case of primary malignant lymphoma of the urinary bladder is described. The classic presentation of gross hematuria and dysuria with a benign clinical course is illustrated. From a review of the literature and our experience, we conclude that localized primary lymphoma of the bladder, especially those with favorable histologic findings, often does not require medical or surgical intervention. Persistent irritative bladder symptoms can be palliated adequately with external beam radiotherapy, while surgical intervention is rarely indicated.     

Primary carcinoid tumor of urinary bladder

Invasive carcinoid tumor of the urinary bladder in a sixty-five-year-old man who presented with painless gross hematuria was documented by light and electron microscopic studies. The presence of 5-hydroxyindoleacetic acid (5-HIAA) and absence of vanillylmandelic acid (VMA) was determined in the neoplastic tissue by chemical analysis. This was consistent with the findings of elevated 5-HIAA and normal VMA in the twenty-four-hour urine sample. Sections of the tumor yielded negative argentaffin and argyrophil reactions. The relevant literature is reviewed.     

Primary melanoma of urinary bladder.

The fourth case of primary melanoma of the bladder is presented together with a review of the previously reported cases and the relevant literature on malignant melanoma in urology. The criteria for classification of the bladder lesion as the primary site are discussed. The eighty-one-year-old female patient was felt not to be suitable for extensive surgery and was successfully treated with a combination of radiation and immunotherapy with recombinant alpha 2 interferon. After previous monthly recurrences of the tumor the patient is in complete remission fifteen months after initiation of therapy. It appears that this form of treatment might be a valuable alternative to radical surgery in elderly patients.     

Primary localized amyloidosis of urinary bladder

Primary localized amyloidosis of the bladder is rare. Two new cases are presented, and 44 cases from the literature are reviewed. The disease tends to occur in a younger age group in men than in women. It presents most frequently with gross painless hematuria, and usually appears at cystoscopy as a tumefied, yellowish, and occasionally ulcerated lesion. The amyloid deposits usually involve suburothelial connective tissue, suburothelial vessels, and less markedly the vesical muscularis. The treatment varies from transurethral resection to total cystectomy with urinary diversion. Transurethral resection appears to be the treatment of choice, if feasible. Close follow-up of the patient is necessary because of the frequency of multiple recurrences, which may require an ablative procedure.     

Primary localized amyloidosis of the urinary bladder.

A case is presented of a woman aged 78 with a primary location of amyloidosis of the bladder. The clinical symptoms and the cystoscopy initially suggested a vesical carcinomatous infiltration.     

Primary non-Hodgkin's lymphoma of the urinary bladder.

Primary non-Hodgkin's lymphoma of the bladder is a rare entity and when found in such an unusual location is often difficult to distinguish from other vesical or extravesical neoplasms. Understanding of the pathobiological characteristics of this malignancy has been hampered not only because of its rarity but also by the previous confusion in its nomenclature. Factors that influence survival most strongly are the stage and the bulk of disease at presentation and the histologic classification of the tumor. We report a case of primary non-Hodgkin's lymphoma of the bladder presenting as a large pelvic mass which dramatically regressed with systemic chemotherapy with simultaneous restoration of the upper dilated urinary tracts. In addition, the incidence, clinical picture, staging procedures, histologic classification and treatment modalities of this disease are reviewed.     

A case of primary urinary bladder and ureter cancer with a choriocarcinoma

An 85-year-old man had planned a laparoscopic right nephrouretectomy for a right lower ureteral cancer, pT1, G3. Two months prior to the surgery, he was re-examined because of continuing macrohematuria. He had a 50 mm tumor in his urinary bladder and tumors from the right upper to lower urinary tract by computed tomographic (CT) examination and cystoscopy. He did not have any metastasis. We diagnosed a cT3N0M0 for the right ureteral cancer and a cT3N0M0 for the bladder cancer. A right nephrouretectomy and cystectomy were then performed. The histopathologic examination revealed an urothelial carcinoma with a choriocarcinoma.
