A rare case of retroperitoneal recurrence as squamous cell carcinoma 10 years after nephroureterectomy.

Introduction: Local recurrence for upper tract urothelial carcinoma typically occurs within 2 years post-surgery. We report a rare case of retroperitoneal recurrence as squamous cell carcinoma 10 years after nephroureterectomy.

Case Presentation: A 67-year-old female was referred to our urology department for a left ureteral tumor.

[Clear Cell Variant of Invasive Urothelial Carcinoma of the Renal Pelvis: A Case Report].

A 74-year-old woman with gross hematuria for 3 months was referred to our hospital. Contrast-enhanced computed tomographic scan showed a mass on the upper-right renal calyx, and retrograde pyelography showed stenoses from the renal pelvis to the renal calyx infundibulum. We performed an endoscopic biopsy, which led to a diagnosis of urothelial cancer.

[A Case of Ureteral Sciatic Hernia Improved by Indwelling a Ureteral Stent].

A 75-year-old woman visited our hospital with left lumber pain and fever. Symptoms, and computed tomography imaging revealed left pyelonephritis. Then she was admitted to our hospital for treatment.

[A CASE REPORT: A PATIENT WITH METASTATIC ADRENOCORTICAL CARCINOMA EXCLUSIVELY TREATED WITH MITOTANE WITH LONG-TERM FOLLOW-UP].

A 77-year-old man with a complaint of impaired consciousness was brought to our emergency department. The patient was referred to our department because of a huge retroperitoneal tumor and multiple pulmonary nodules detected on computed tomography. Owning to an abnormally high level of dehydroepiandrosterone sulfate, right adrenal cancer was suspected.

[A Case of Pneumatosis Cystoides Intestinalis during Castration-Resistant Prostate Cancer Treatment].

A 65-year-old man received docetaxel for prostate cancer. Eight months later, we observed abdominal free air and pneumatosis cystoides intestinalis by computed tomography. Pneumatosis cystoides intestinalis can be caused by various etiologies.

[A Case of Choroidal and Brain Metastases from Castration-Resistant Prostate Cancer].

Choroidal and central nervous system metastases from prostate cancer are extremely rare. We report a case of choroidal and brain metastases from castration-resistant prostate cancer (CRPC). A 75-year-old male patient with metastatic CRPC presented with a 1-week history of a decrease in visual acuity in his left eye.

[DISSEMINATED CARCINOMATOSIS OF THE BONE MARROW WITH UROTHELIAL CARCINOMA].

Disseminated carcinomatosis of the bone marrow with urothelial carcinoma in a 75-year-old man: A case study. A 75-year-old-man had first medical examination due to gross hematuria. The imaging study and cystoscopy revealed left ureteral and bladder tumor.

[A case of retroperitoneal angiosarcoma effectively treated with recombinant interleukin-2].

Angiosarcoma is rare and highly malignant vascular neoplasm, and primary retroperitoneal angiosarcoma is extremely rare. Preoperative diagnosis is very difficult because there are no specific imaging features, and definitively effective treatment has not yet been established. We recently treated a patient with primary retroperitoneal angiosarcoma in which a prompt and exact diagnosis was difficult to obtain.

[A case of pneumomediastinum during BEP (bleomycin, etoposide, cisplatin) chemotherapy for testicular cancer].

We report a case of drug-induced pneumomediastinum by bleomycin in testicular cancer, which is extremely rare ; to our knowledge, only 3 cases have been reported. A 28-year-old man presented with a left testicular mass. He underwent radical left inguinal orchiectomy that demonstrated a seminoma, pT3N0M0.

[Retrospective analysis of predicting biochemical recurrence after initial radical prostatectomy].

We evaluated clinical outcomes of radical prostatectomy in 244 patients who had undergone radical prostatectomy as initial treatment from January 2000 to December 2011, and were followed up for more than 6 months. Biochemical recurrence after prostatectomy was defined as prostate-specific antigen (PSA) level of at least 0. 2 ng/ml.

[Low-dose docetaxel, estramustine and dexamethasone combination chemotherapy for hormone-refractory prostate cancer].

The objective of this study was to evaluate the efficacy and safety of low-dose docetaxel, estramustine and dexamethasone combination chemotherapy in patients with hormone-refractory prostate cancer (HRPC). Sixty-nine patients with HRPC were enrolled. Docetaxel was given at a dose of 25 mg/m(2) on days 1 and 8 every 3 weeks, oral estramustine 280 mg twice daily on days 1 to 3 and 8 to 10, and oral dexamethasone 1 mg daily throughout the course.

[Segmental infarction of the testis presenting as acute scrotum: a case report].

We report a case of segmental testicular infarction that is a rare and usually idiopathic. The patient is a 36-year-old man who presented with acute right scrotal pain and swelling. Scrotal ultrasound demonstrated a round hypoechoic lesion and magnetic resonance imaging (MRI) findings could not rule out intratesticular hemorrhage or necrotic tissue associated with malignant neoplasm.

[Metanephric adenoma: report of two cases].

We report 2 cases of metanephric adenoma a rare form of adenoma. One case occurred in a 54-year-old male preoperatively diagnosed with renal cell carcinoma who underwent left partial nephrectomy for a tumor 2 cm in size. Histology revealed a tumor with papillotubular structures consisting of small, uniform tumor cells.

[A case of hormone/docetaxel-refractory prostate cancer in which PSA level decreased after docetaxel+zoledronic acid treatment].

The patient was a 63-year-old man who had a recurrence and bone metastasis of prostate cancer after total prostatectomy. He was diagnosed with prostate cancer refractory to hormones. Subsequently, the PSA level decreased after docetaxel therapy, but then gradually increased.

[Splenosis mimicking local recurrence after radical nephrectomy: a report of two cases].

Splenosis is autotransplantation of splenic tissue and usually follow traumatic or surgical rupture of the spleen. We report two cases of splenosis which presented as a local recurrence after radical nephrectomy for left renal cell carcinoma (RCC). The patients were a 65- and a 71-year-old male, who had been operated for RCC including splenectomy because of disrupture of the splenic capsule 8 and 9 years earlier respectively.

[Clinical study of 38 cases of pheochromocytoma --correlation between the instability of intraoperative blood pressure and 24-hour urinary vanillylmandelic acid].

Pheochromocytoma is a rare tumor of chromaffin tissues most commonly arising from the adrenal medulla. We retrospectively reviewed the records of 38 patients with pheochromocytoma who underwent surgical treatment between 1977 and 2004 at our Yokohama City University Medical Center and Yokohama City University Hospital. Twenty two patients (57.

[Clinical significance of pelvic lymph-node dissection for the patients with locally invasive bladder cancer--correlation between the number of retrieved lymph nodes and prognosis].

The objective of this study was to know the effects of pelvic lymph node dissection on the survival of the patients who received radical cystectomy without neoadjuvant chemotherapy or radiotherapy. Between 1984 and 2000, 104 patients underwent operation at our institution for tumors clinically diagnosed as locally invasive bladder cancer (T2-4NxM0). Survival rates and 8 prognostic factors (age, sex, size, multiplicity, type, pT, N, pv) were analyzed by uni- and multivariate analysis.
