Plexiform Penile Neurofibroma: A Case Report of a Rare Entity in a Pre-Pubertal Child.

Neurofibromatosis is a group of genetic disorders and consists of 2 forms: Neurofibromatosis type 1 (NF-1) and Neurofibromatosis type 2. The most common is the NF-1 which is also known as von Recklinghausen's disease. The presentation and clinical manifestations of this condition vary greatly. It is usually characterized by café-au-lait spots and neurofibromas. In this report, the case of a 12-year-old boy with NF-1 is presented. The boy has several café-au-lait spots along with inguinal and axillary freckles. He was found to have a rare and unusual neurofibroma of the penis.

Percutaneous nephrolithotomy in a case of retrorenal colon: A descriptive approach and literature review.

INTRODUCTION: Percutaneous nephrolithotomy procedure is generally used to treat stones resistant to other treatment modalities. Colonic perforation even though rare, is a serious complication that increases patient's morbidity. This case report describes the case of a patient with retrorenal colon who underwent percutaneous nephrolithotomy for management of pelvis/lower calyceal staghorn stone. CASE PRESENTATION: A 63-year-old female patient presented for the management of a staghorn pelvis-lower calyceal stone. The patient had a preoperative computed tomography scan of the abdomen and pelvis that showed an incidental finding of left retrorenal colon. Under computed tomography scan guidance, a nephrostomy tube was successfully placed by an interventional radiologist, and then she underwent percutaneous nephrolithotomy. CONCLUSION: This case report aims to stress on the importance of doing a computed tomography scan whenever a prior abdominal surgery is performed. We strongly believe that gastrointestinal injuries could be avoided by using computed tomography guided access in high risk patients.
