Plexiform Lesion with Inflammation

Here a parent artery (left) gives rise to a plexiform lesion with round and slit-like vascular spaces lined by prominent endothelial cells. There is no media around the plexiform lesion. Surrounding the lesion are chronic inflammatory cells including T and B lymphocytes and macrophages [1]. The inflammation was limited to the arterial lesions.
