However, the concurrence of features of both vascular tumors in the same specimen of some patients raises the question whether these tumors exist on a continuum. Herein, we report a dynamic transformation between both tumors within a single patient, which suggests they are two variants of the same vascular tumor. Copyright ? 2003 S.
