Bladder neoplasms associated with augmentation cystoplasty have been reported to date in 12 patients. We add 2 cases: 1 with invasive transitional cell carcinoma involving the native bladder and bowel segment, and 1 with a poorly differentiated invasive oat cell (small cell) carcinoma confined to the bladder. The predisposing factors ...

Intramuscular hemangiomas make up less than 1% of all hemangiomas [1]. These invasive and aggressive lesions appear to have a predilection for large muscle masses. They can be strikingly aggressive in the head and neck, and persistence despite radical treatment is common. Spontaneous resolution in adults to our knowledge has ...

Theories about the nature of cavernous hemangiomas have been reviewed. Most authors believe that such vascular tumors are congenital. The influence of pregnancy on the growth of these tumors was exemplified in a case report, and explanatory mechanisms were offered. Occurrences of cavernous hemangiomas that involve the foot were reported ...

Hemangiomas, although frequently found elsewhere, are rarely encountered in the adrenal gland. Only 17 surgical cases of adrenal hemangiomas have been reported, with an additional case not surgically treated. The pertinent literature has been reviewed. Two additional cases, one identified preoperatively and both removed surgically, are presented herein. Ultrasonograms and ...

The incidental discovery of a cavernous hemangioma in an apparently normal incus found during pathological examination is reported.

We chose a policy ...

Patients presenting with rare primary signet-ring cell carcinoma of the bladder are often found to be in renal failure and to have distressing symptoms of bladder instability. Their clinical course most often is rapidly fatal, and radical cystectomy with urinary diversion offers the only hope of increasing longevity. We herein ...

Verrucous hemangioma is an infrequent variety of deep-seated capillary or cavernous hemangioma with reactive epidermal hyperplasia and a superficial component indistinguishable from those of angiokeratoma. Four cases of verrucous hemangioma are reported herein. Verrucous hemangiomas are usually congenital lesions which do not resolve spontaneously and have a tendency to recur ...

In the newborn, intraperitoneal extravasation of urine from a urachal laceration may follow an attempt at umbilical artery catheterization. Clinical results of this injury are neonatal ascites, anuria, and azotemia. Herein, we describe a case of iatrogenic bladder injury with successful management following late detection. The anatomy of the urachus ...

We report on a girl with hamartomatous intestinal polyps and a large mass that involved most of the posterior wall of the bladder, which on microscopic examination had the characteristics of a hamartoma. Hamartomas are among the rarest of bladder tumors. Our case is only the third reported under this ...

We report a case of successful urinary undiversion and implantation of an artificial urinary sphincter in a 73-year-old man, who had undergone ileal loop urinary diversion elsewhere for treatment of urinary incontinence secondary to transurethral prostatectomy. The rationale for our decision to perform undiversion is presented. Evaluation of patient history ...

Three cases of adenocarcinoma involving the bladder and consisting mainly of signet-ring-shaped cells are presented. Each case represents a different form that the lesion may take, and these forms are compared. This unusual neoplasm has a worse prognosis than transitional cell carcinoma of the bladder, possibly because of factors that ...

The role of urologic disease and manipulation of the genito-urinary tract in the pathogenesis of gram-negative bacteremia has been long recognized. Among these organisms, species of providencia genus have been increasingly reported. We describe a 17-year-old male paraplegic who developed septic shock due to Providencia Stuartii following urinary tract manipulation ...

Tumors of the umbilical cord are extremely rare. Only two types are recognized: hemangioma and teratoma. A case of hemangioma of the cord prompted a review of the world literature that uncovered 17 other cases, bringing the total number of known cases up to 18. Our case is the first ...

The vesicourachal diverticulum in association with other urological anomalies is a rare condition. It is easily demonstrated by ultrasound examination.
