Angiolymphoid hyperplasia with eosinophilia in association with a vascular malformation.
A unique case is presented in which a lesion of angiolymphoid hyperplasia occurs in association with a vascular malformation. The skin and the intravascular lesion showed, on microscopic examination, angiolymphoid hyperplasia, which to my understanding, is a reactive process. The nodule represents, in my view, satellite lesions of the A-V malformation--in other words a skin manifestation of the intravascular process. The same phenomenon has been reported in some pyogenic granulomas and hemangiomas.
