We confirmed the presence of a prostate-type gland in the epididymis of a 30-year-old white man by immunohistochemical analysis using prostate specific antigen and prostate specific acid phosphatase. We suggest possible histogenetic mechanisms for such previously undescribed morphological heterogeneity within this wolffian duct derivative.

Renal vein thrombosis may lead to significant renal impairment, even death, yet therapy remains controversial. Thrombolytic therapy in general may be attended by significant hemorrhagic complications and has not been used widely in children. We treated a 9-year-old boy with antithrombin III deficiency and acute renal vein thrombosis in a solitary kidney with a selective 48-hour infusion of low dose urokinase with return of renal function. Minor bleeding from a fresh surgical incision was the only morbidity. Such use of fibrinolytic agents in children with acute renal vein thrombosis may prevent significant renal impairment and deserves further clinical trials.

A 34-year-old white man presented with severe penile cellulitis following injection of epoxy glue into the shaft of the penis. Preoperative xeroradiography and ultrasonography localized the hardened masses of glue to the left corpus cavernosum and subcutaneous tissues. Under the guidance of intraoperative ultrasonography this foreign material was removed surgically. Postoperatively, the cellulitis resolved promptly and xeroradiography demonstrated no residual fragments. Although various modalities, including computerized tomography and roentgenography, are available to detect foreign bodies in soft tissues, xeroradiography and ultrasonography are ideally suited for use in the male external genitalia.

We report an unusual case of isolated metastatic prostate adenocarcinoma to the lung and compare the deoxyribonucleic acid content of the primary tumor to the metastases using flow cytometry.
