Transitional cell carcinoma of the fossa navicularis of the male urethra.
We report a case of transitional cell carcinoma arising in the fossa navicularis, a portion of the male urethra ordinarily lined by squamous epithelium. This is the third reported case of transitional cell carcinoma of the distal urethra. The neoplasm metastasized to superficial inguinal lymph nodes.

Spontaneous retroperitoneal hemorrhage: a diagnostic challenge.
Spontaneous retroperitoneal hemorrhage can present a difficult diagnostic dilemma. We present 4 illustrative cases within the last 2 years at our institutions. Excluding traumatic injury to the retroperitoneum and abdominal aortic aneurysms, about 75 per cent of the cases are related to neoplasms or vascular anomalies. An awareness of predisposing disease states is important. A high index of suspicion and an aggressive diagnostic approach are necessary. If evaluation does not disclose an etiology for retroperitoneal hemorrhage then non-operative management may be considered. This is especially true if an underlying systemic condition is present.

New alternatives in gallstone treatment.
Within the past few years, a number of new treatment modalities for gallbladder stones have become available. Laparoscopic cholecystectomy has proved as safe as traditional surgical cholecystectomy, without the discomfort and lengthy recuperation associated with a large abdominal incision. Several other new treatments also have been investigated, including percutaneous cholecystolithotomy, peroral drug chemolysis, extracorporeal shock wave lithotripsy, and methyl-tert-butyl ether lavage. The relative merits and disadvantages of these treatments, compared to each other and to standard cholecystectomy, are described herein.
