title: Intra-arterial angiolymphoid hyperplasia with eosinophilia.
abstract: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare skin disorder of unknown etiology. This paper describes the case of a 34-year-old man with a lesion located on the right part of his forehead. Microscopically, it displayed a typical morphology of ALHE. However, it was exceptional by its intra-arterial location and its prominent lymphocytic rim-like component. Differential diagnoses, with special emphasis to organized thrombosis and juvenile arteritis, are discussed here.
