Angiolymphoid hyperplasia with eosinophilia: report of a case with penile lesions.
A case of angiolymphoid hyperplasia with eosinophilia of the penis is reported. In addition to the proliferation of swollen endothelial cells with features of histiocytes ("histiocytoid endothelial cells"), the lesions also showed a remarkable proliferation of pericytes both in relation to formed vascular channels and away from them. The authors consider that the inflammatory component is associated with even the earliest stages in the development of the lesions and that it not be dismissed as secondary.
