A review of our records between 1993 and 1998 identified 25 patients with transitional cell carcinoma of the bladder who were less than 40 years old, 22 males and 3 females. The youngest patient was 19 years old. At the time of diagnosis 16 patients had superficial (Ta/T1) and 9 had invasive disease. Twenty-four patients were followed up for a period of 3-71 months (mean: 19.2 months). The recurrence rate for patients with superficial disease was 12.5%, and the progression rate for patients with invasive disease was 77.7%. We concluded that the patients under 30 years of age presented with lower grade and lower stage disease than those over 30. Transitional cell carcinoma of the bladder in young adults has a natural history similar to that seen in older patients. Accordingly, all patients, regardless of age, should be treated as aggressively as necessary on the basis of the stage and the grade of the tumour.
Here we describe the clinical, radiologic, histopathological and immunohistochemical features of a rare spontaneous rupture of renal angiosarcoma detected in the left kidney of a 55-year-old male. Due to the rarity of this neoplasm (less than 15 cases have been reported), there is no unanimous concensus for therapy following radical nephrectomy. In our case there was no flank trauma and retroperitoneal haematoma around the left kidney was seen on computed tomography. The patient underwent left radical nephrectomy and died about 3 months after operation due to multiple bone and liver metastases. To our knowledge, this is the first report of spontaneous rupture of renal angiosarcoma and we suggest that it should be borne in mind that renal angiosarcoma may be a cause of retroperitoneal haematomas.
The aim of this study is to review 9 cases with urinary tract hydatid disease in terms of symptoms, findings, laboratory tests, radiological findings and treatment modalities. There were 7 males and 2 females with a mean age of 33.6 years (range from 7 to 67 years). In 6 patients hydatid cyst was located in the kidney (1 involved the liver), in 2 the cysts were in the paravesical and retrovesical region (1 coexisted bladder tumor) and 1 the cyst was located adrenal gland. The investigations included urinalysis, eosinophil count, Casoni skin test, indirect haemagglutination test (IHA), transabdominal ultrasonography (TAUS), intravenous urography (IVU) and computed tomography (CT). All patients underwent various surgical procedures and were followed-up for an average of 3 years (range: 1 month to 5 years) period in terms of complications and recurrence rates. The most common symptom was lumbar or abdominal pain. Eosinophilia was seen in 4 patients (44.4%), IHA positivity in 3 patients (33.3%) and Casoni skin test were positive in 3 patients (33.3%). The most diagnostic method of radiological investigations was abdominal pelvic CT (100%). After surgical treatment, in mean a 3 year (range: 1 month to 5 years) follow-up period, no complication and recurrence were seen. Hydatid disease of the urinary tract is relatively uncommon and is likely to cause considerable diagnostic difficulties for clinicians and radiologists: therefore, it should be born in mind in the differential diagnosis of space-occupying lesions of the urinary tract.
We have documented the data of squamous metaplasia of the bladder in 14 patients who had undergone cystoscopies for different reasons. In two biopsies, there were marked keratinization and cellular atypia. One of these two subjects was diagnosed as squamous carcinoma of the prostate and transitional cell carcinoma of the bladder. The lesions of 8 female patients were on the trigone and evaluated as normal anatomical variants due to hormonal changes. Three of them were remarkable because of recurrent urinary infections. Apart from the two male patients with squamous cell carcinoma of the prostate the two male patients with current squamous metaplasia have been following up. In this study, we have also reviewed the relationship between squamous metaplasia, infection and malignancy.
