title: Angiolymphoid hyperplasia with eosinophilia. An electron microscopy study.
abstract: Ultrastructural investigation of a case of papular (dermal) lymphoid hyperplasia with eosinophilia revealed in the proliferating tissue rounded inclusion bodies made up of smaller particles which formed within the lysosomal vacuoles and sometimes occupied a large proportion of the cytoplasm. The bodies also occur in the extracellular spaces. Apart from this, groups of mosaic-like particles and concentric bodies with a central core suggesting viral provenance were demonstrated.
