Abstract
|
|
|
|
Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign vascular tumor characterized by the development of endothelial-lined papillary projections in the vascular lumen. Most authors believe that IPEH represents an unusual pattern of organizing thrombus, implying that a thrombus is the initial cause. A 13-year-old boy came to hospital because of a purpuric patch and violaceous plaque on his right forearm. Clinically, the lesions were thought to be a hemangioma or other vascular malformation. Therefore, we treated him with intense pulsed light (IPL) four times. After treatment, the initial skin lesions were erythematous and edematous and a new bluish mass and multiple scattered subcutaneous nodules appeared near the original skin lesions. Histologic examination of the new bluish mass showed an organic thrombus and endothelial-lined capillary projections in the dilated vascular lumen, compatible with IPEH. Here, we report an interesting case of IPEH after IPL treatment in a 13 year-old boy.
