[Urothelial carcinoma involving the renal calyce revealed due to brain metastasis]. / Carcinome urothélial sur un calice rénal exclus révélé par une métastase cérébrale.

Urothelial carcinoma is usually characterized by severe symptoms including macroscopic haematuria. We here report the case of a female patient without a history of smoking or urothelial carcinoma, making it, to our knowledge, a unique case and a first case of urothelial carcinoma revealed by brain metastasis.

[Bladder exstrophy with adenocarcinoma in an adult patient: a case report]. / Adénocarcinome sur une exstrophie de vessie chez un patient adulte: à propos d'un cas.

Bladder exstrophy is rare malformation pathology with an incidence of about 1 in 50,000 newborns. Not treated in time exposes to two main complications: kidney failure and bladder plaque cancer with a risk up to 200 times normal, which usually occurs around the fourth and fifth decade. In 95% it is adenocarcinoma and 5% squamous cell carcinoma. We present a rare case of adenocarcinoma developed on a bladder exstrophy in a 61-year-old patient who underwent an excision of the bladder plate carrying the whole tumor mass with a non-continent urinary diversion type bricker.

Cause rare d'insuffisance rénale aigue: géant calcul de vessie chez une jeune femme: A rare cause of acute renal failure: giant urinary bladder stone in a young woman.

Giant urinary bladder stone is defined as a stone with a weight higher than 100 g. It is rare in women, accounting for approximately 2%. Its occurrence in the urinary bladder does not exceed 5% of the whole of the urinary tract. In women, the occurrence of urinary bladder stone is often secondary to a predisposing factor including intravesical foreign body, neurogenic bladder, repeated urinary infections, a history of surgery treating stress urinary incontinence. Therefore, there are some patients with a bladder stones without any obvious cause, such as primary idiopathic stone. We here report the case of a 31-year old patient with giant urinary bladder stone affecting the superior part of the urinary tract causing acute renal failure. The patient initially underwent bilateral nephrostomies to drain the superior part of the urinary tract; then giant urinary bladder stone was removed by open cystolithotomy. Etiological assessment didn't show any obvious cause.

[Urinary incontinence revealing vescicouterine fistula: about a case]. / Incontinence urinaire révélant une fistule vésico-utérine: à propos d'un cas.

Vescicouterine fistula (VUF) is a rare lesion accounting for only 4% of all urogenital fistulas. It is most often secondary to cesarean section and forms a connection between the bladder and the uterus. We report the case of a young patient with VUF secondary to cesarean section. This study aims to investigate the clinical and therapeutic features of this disorder.

Kaposi's sarcoma: HIV-negative man with isolated penile localization.

Kaposi's sarcoma is the malignant proliferation of the endothelial cell vessels. Its genesis is still unclear; however, it seems to be related to the herpes virus infection (HHV-8). This neoplasia usually affects the lower limbs and the affected persons are mostly from the Mediterranean region. The exclusive penile localization of the Kaposi's sarcoma in a patient with a negative HIV serologia is exceptional. Our case is of a 73-year old patient with a negative HIV serology presenting an exclusive penile localization of the Kaposi's sarcoma treated by radiotherapy.
