A 45-year-old man with spinal injury and diabetes mellitus who complained high fever and progressive enlargement of left intrascrotal mass visited to our hospital. Preoperative ultrasonography demonstrated epididymitis and abscess formation. Left high orchiectomy was performed because testicular tumor could not be denied. Epididymis was replaces by bright yellow mass associated with abscess and adhered to testis strongly. Histopathologically, the mass diagnosed xanthogranulomatous epididymitis consisted of foamy macrophages and chronic inflammatory cells. This is the first case in Japanese medical literature.
Malignant neurofibroma of the urinary bladder is a very rare entity and usually associated with von Recklinghausen’s disease. We present the first case of sporadic malignant neurofibroma of the urinary bladder and a review of the literature.
A rare case of bilateral spermatocele developed 17 years after vasectomy was presented. A forty-seven year old man visited to our hospital with a chief complaint of swelling of bilateral intrascrotal contents. Sonographic findings demonstrated multilocular lesions of the bilateral intrascrotal contents. Operative procedure revealed bilateral cysts originating from the caput of the epididymis. Bilateral epididymectomy were performed. It was diagnosed as spermatocele because of demonstration of spermatozoa in the cystic fluid. We concluded that bilateral spermatocele has been induced by prolonged increased pressure of the intraepididymal duct following vasectomy 17 years ago.
The Biopty-gun is a useful tool in conducting percutaneous renal biopsies, but bleeding is still a significant complication. To reduce the rate of severe bleeding complications, we attempted a new method of renal needle biopsy using a retrograde access technique. Retrograde puncture of the renal calyx was performed using the Lawson nephrostomy kit. The 18-gauge needle of the Biopty-gun was inserted along the puncture wire and fired. A 7-french pigtail catheter was retained in the renal pelvis for a few days following the procedure. This biopsy is a promising and safe technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
