[A case of retroperitoneal bronchogenic cyst].

A 59-year-old hypertensive man was referred to our hospital with a retroperitoneal cystic tumor, measuring 6 cm in diameter that was detected by an ultrasound examination during routine check-up 2 years before coming to our department. During the 2-year follow-up, the cystic tumor gradually increased in size. The patient also became hypertensive with slightly elevated urine levels of noradrenaline and dopamine, while the plasma catecholamines and their metabolites in the urine were within the normal range.

The impact of radical prostatectomy on patient well-being: a prospective urodynamic study focused on detrusor function.

Prostate cancer is common in aged men and radical prostatectomy is established as a therapeutic measure. However, to date there is little information about its impact on voiding function. We conducted a prospective clinical study to elucidate the impact of radical prostatectomy on voiding function in 17 patients with prostate cancer, by urological evaluation including filling and voiding cystometry (pressure flow study).

Aggressive angiomyxoma in the scrotum expressing androgen and progesterone receptors.

Aggressive angiomyxoma is a rare benign mesenchymal myxoid tumor that arises from the pelvic soft tissues and perineum in relatively young females. This tumor has the ability to infiltrate locally and has a high risk of local recurrence after extirpation, but no potential to metastasize. We report here a rare case of aggressive angiomyxoma that developed in the scrotum of a 47-year-old male.

[A case of primary transitional cell carcinoma of the prostate].

A 77-year-old man was referred to our hospital with a complaint of dysuria and right ischiodynia. He had had a hemi-thyroidectomy for thyroid cancer and right cervical lymphadenectomy three years and one year, respectively, before this visit. Prostate cancer was strongly suspected by transrectal examination with prostate specific antigen (PSA) elevated to 77.

[A case of inflammatory myofibroblastic tumor of the retroperitoneum].

Here we report a rare case of inflammatory myofibroblastic tumor of the retroperitoneal space. A 46-year-old woman had had microscopic hematuria for 5 years. Ultrasonographic examination for screening revealed two solid tumors adjacent to the right kidney.

Chromophobe cell renal carcinoma with acquired cystic disease of the kidney in a long-term hemodialysis patient.

We report a rare case of chromophobe cell renal carcinoma found in a 52-year-old female who had received hemodialysis therapy for 13 years. She was diagnosed as having a left renal tumor 7.5 cm in diameter with acquired cystic disease of the kidney (ACDK) by ultrasonographic examination during periodical systemic screening.

[Clinicopathological significance of neoadjuvant hormonal therapy prior to radical prostatectomy: whole section analysis].

We investigated whether the histopathological effect (cell viability) of neoadjuvant hormonal treatment before radical prostatectomy for clinically localized prostate cancer is involved in the biochemical outcome, i.e., androgen independency.
