Leiomyoma of the bladder: A case report

A case of leiomyoma of the urinary bladder in a 20-year-old man is reported. The patient presented with severe frequency and perineal burning at the end of urination along with microscopic haematuria. Enucleation of the tumour was performed because transurethral biopsy revealed leiomyoma. The prognosis of these tumours is excellent

Evaluation of needle biopsy in the diagnosis of prostatic carcinoma in men with prostatic intraepithelial neoplasia

Prostatic intraepithelial neoplasia (PIN) is considered a premalignant lesion of the prostate. It is often encountered in prostate needle biopsy in cases where no cancer is identified. In order to evaluate its importance 25 patients with PIN in a former prostate needle biopsy underwent a second ultrasound guided needle biopsy. The first biopsy was performed in all patients as a result of positive DRE. In 13 patients (52%), prostate cancer was identified in the second specimen. All presented with high or intermediate grade PIN in the first biopsy. PSA values were compared with PIN grade and cancer presentation in the second biopsy, although no statistically significant difference was proven. In conclusion, when PIN is discovered in prostate needle biopsy in patients with positive DRE, a second biopsy has to be performed in order to exclude the possibility of a prostate carcinoma

RENAL-CELL CARCINOMA PRESENTING AS A LARGE ABDOMINAL-MASS WITH AN EXTENSIVE PERITONEAL METASTASIS

We report a case of renal cell carcinoma with an extensive intraperitoneal metastasis at the time of diagnosis. This type of metastasis is very rare for renal cell carcinoma and is identified in only 1% of the metastases at autopsy. The findings of computed tomography are presented

Encrusted cystitis and pyelitis

Encrusted cystitis (EC) and encrusted pyelitis (EP) are rare chronic inflammatory diseases of the bladder and renal pelvis, respectively, and are characterized by mucosal inflammation with deposits of ammonium magnesium phosphate on the urothelium. Corynebacterium urealyticum is the pathogen responsible in the vast majority of cases. We report 4 cases of EC and 1 case of EP, In 1 case of EC Ureaplasma urealyticum was isolated as the microorganism responsible. To the best of our knowledge, U, urealyticum-induced EC has never been reported previously. Copyright (C) 2000 S. Karger AG, Basel
