Intravascular Papillary Endothelial Hyperplasia: Case Report of a Recurrent Masson's Tumor of the Finger and Review of Literature.

Intravascular papillary endothelial hyperplasia (IPEH), often referred to as Masson's Tumor, is an uncommon yet benign vascular disease of the skin and subcutaneous tissues. It usually arises within a blood vessel, but is considered to be a non-neoplastic reactive endothelial proliferation commonly associated with vascular injury. Although it is rare, knowledge of this disease is important as it may mimic other benign and malignant tumors, especially angiosarcoma, which may lead to unnecessary aggressive management.

Magnetically Controlled Growing Rods: Influence on Intraoperative Fluoroscopic Imaging: A Case Report.

Case: A 7-year-old boy with severe congenital scoliosis and impending thoracic insufficiency syndrome underwent uneventful single magnetically controlled growing rod (MCGR) insertion and removal of his ipsilateral rib-based distraction implants at our institution. Intraoperative fluoroscopy imaging revealed an artifactual bend (S-distortion) of the rod actuator after placement. This artifact was eliminated by moving the image intensifier further from the patient.
