Comparison of Different Treatment Schedules of Mitomycin C Intravesical Instillation in High-Risk Superficial Bladder Cancer Patients.

Unlabelled: ZIEL:  Diese Studie erfolgte zum Vergleich der Wirksamkeit einer intravesikalen Instillation von Mitomycin C (MMC) zur Prävention eines nicht muskelinvasiven Ta- oder T1-High-Risk-Harnblasenkarzinoms (NMIBC) unter Verwendung verschiedener Schemata.

Material Und Methoden:  Diese retrospektive Kohortenstudie wurde bei 152 Patienten durchgeführt, die zwischen April 2009 und September 2016 mit einer intravesikalen MMC-Injektion behandelt wurden. Der mittlere Nachbeobachtungszeitraum lag bei 32,67 Monaten.

Pulmonary leiomyomas in a patient with bilateral renal cell cancer mimicking pulmonary metastases.

Pulmonary benign metastasizing leiomyoma (PBML) characterized by uterine leiomyoma in the lung is very rare. Here we report the case of a 55-year-old woman with a history of surgically resected multiple uterine leiomyomas who was histopathologically diagnosed with PBML associated with bilateral primary renal cell carcinoma (RCC). Clinicians should be aware of this unusual entity and consider pulmonary leiomyoma as a differential diagnosis in asymptomatic women with primary RCC and a history of hysterectomy for leiomyoma.

A giant non-functional adrenocortical carcinoma presenting with acute kidney injury.

Hormonally inactive adrenocortical carcinoma (ACC) is a rare disease where abdominal discomfort and back pain are common presenting symptoms due to mass effect from a large tumor. Acute kidney injury (AKI) from retroperitoneal tumors has rarely been reported. The most common etiologies include venous thrombosis, ureteral compression, or both.

Inlay buccal mucosal graft for reoperative posterior urethroplasty.

Posterior urethral distraction injury following major pelvic trauma is a surgical challenge. Although rarely seen, cases of failure after formal urethral reconstruction are even more problematic. We adapted the concept of augmented free buccal mucosal grafts, which have been successful in anterior urethroplasty, for repairing the posterior urethra in these rare cases with the aim of reducing the likelihood of penile chordee postoperatively.

Retroperitoneal mixed germ cell tumor mimicking a renal neoplasm: a case report.

Retroperitoneal malignant germ cell tumors (GCTs) are rare and of uncertain origin. Almost all retroperitoneal GCTs with seminomatous histology have been reported in male patients. Pediatric hypertension in a girl secondary to a retroperitoneal mixed GCT (dysgerminoma plus mature monodermal teratoma) has not been reported previously in the literature.

Malignant mesenchymal tumor with leiomyosarcoma, rhabdomyosarcoma, chondrosarcoma, and osteosarcoma differentiation: case report and literature review.

A case of malignant mesenchymoma of the bladder containing leiomyosarcoma, rhabdomyosarcoma, chondrosarcoma, osteosarcoma, and myxomatous components is described. The primary pedunculated tumor measuring 14×13×7 cm and weighing 343 g arose from the left trigone of the bladder and was treated by total cystectomy. The histogenesis of malignant mesenchymomas and their optimal management strategy and prognosis remain uncertain.

Micturitional headache in a young girl.

A 16-year-old girl came to our emergency department because of severe headache. For the past 3 years, she had presented at several emergency departments with a similar problem. When she was hospitalized for further investigation, she developed severe arterial hypertension for which an unusual cause was found by imaging of the abdomen.
