An etiological assessment of a deep vein thrombosis led to the discovery of a renal tumor collision: Case report.

INTRODUCTION AND IMPORTANCE: The thromboembolic complication of kidney's tumor is rare, and they can be the reason for the discovery of those tumor. Also the collision kidney tumor, such as a simultaneous occurrence of different histological types of adjacent neoplasms in the same organ is rare. CASE PRESENTATION: We report a patient diagnosed with a kidney tumor discovered in the context of an etiological assessment of thrombosis, presenting with pulmonary embolism and deep vein thrombosis of the lower limb. This tumor treated by a cytoreductive nephrectomy. The histologic diagnosis of PRCC (Papillary Renal Cell Carcinoma) associated with a chromophobe cell carcinoma and sarcomatoid component was rendered. CLINICAL DISCUSSION: The development of the tumor process and its progression to the metastatic stage is largely favored by the hypercoagulable state, and the cancer itself promotes the appearance of thrombo-enmbolic phenomena due to this phenomenon. Two major studies recommend that immediate cytoreductive nephrectomy should be offered to metastatic patients with a good general condition. CONCLUSION: A renal tumor collision is rare, whereas the risk factors for a renal tumor collision are the same as a renal tumor without collision, just as the management of a metastatic renal tumor is the same. Understanding the thromboembolic physiopathology in the case of kidney cancer has made it possible to optimize management.

Management of a localized prostatic adenocarcinoma despite the very high rate of PSA and the large tumor mass: Does PSA level indicate the stage of prostate cancer?

Prostate-specific antigen (PSA) is a marker specific to the prostate gland, and it is, therefore, possible to observe an increase in PSA above 4 ng/mL in cases of benign prostatic hypertrophy and cancer. But according to studies, a very high PSA level is most likely synonymous with metastatic prostate cancer. Our rare case concerns the management of a localized prostatic adenocarcinoma despite a very high PSA level of over 3000 ng/mL, with an enormous volume of prostate without invasion or distant metastasis. A very high PSA level can probably be a sign of metastatic prostatic adenocarcinoma, but not necessarily.

Management of an accidental mass in a monorchidic patient discovered during infertility: a case report.

Testicular cancer is the most frequent type of cancer in the young adult men, it is relatively rare. Infertility is an important risk factor for testicular cancer, with a doubled risk of developing cancer compared to the general population. The standard treatment for testicular cancer is the radical orchiectomy, but partial orchiectomy or testicular sparing surgery (TSS) is indicated for small masses, as many experiences, have shown that many small masses found incidentally turn out to be benign. Case presentation: The authors report the case of a patient presented for primary infertility, a clinical examination for left-sided gynecomastia without inflammatory signs. A testicular MRI revealed a 7 mm suspicious nodule in the posterior-inferior aspect of the right testicle, with contrast enhancement in the juxta-tumoral area corresponding to a heterogeneous area on ultrasound. Due to the lesion described on MRI, monorchidism, and azoospermia, a TSS combined with testicular biopsy and testicular sperm extraction was indicated. Clinical discussion: The reference treatment for testicular cancer is the radical orchiectomy, but in some selected situations, partial orchiectomy or TSS is indicated, as many experiences have shown that many small masses found incidentally turn out to be benign. Conclusion: This case suggests that TSS or partial orchiectomy for small nonpalpable testicular masses in monorchidic patients can provide an excellent outcome for the patient.

Rare case of gangrenous cystitis revealed by acute peritonitis.

Gangrenous cystitis complicated by intraperitoneal perforation is an extremely rare pathology, the major etiopathogenic factor is ischemia of the bladder wall, it has disappeared with the advent of antibiotic therapy and the development of means of bladder drainage. We report a case of a 17-year-old patient, who had a medical history of spinal cord transection by stabbing, who presented a chronic urinary retention leading to a gangrenous cystitis, a surgical exploration was performed and excision of necrotic tissues and reconstruction of the wall bladder with a well recovery.

Pyoperitoneum revealing a spontaneous renal forniceal rupture due to ureteropelvic junction syndrome: About a rare case report.

Extravasation of urine following forniceal rupture of a pelviureteric junction is a rare complication; the existence of pyonephrosis can result to retroperitoneal abscess but its fistulization into peritoneal cavity is exceptional. We report a case of a 22-year-old men who presented a clinical aspects of peritonitis, abdominal CT scan findings suggested retroperitoneal peritonitis by rupture of the fornix. This case emphasizes an unusual presentation of pyonephrosis with peritonitis and pyoperitoneum caused by a ureteropelvic junction syndrome.
