Eruptive pseudoangiomatosis.

We describe two children with acute onset and spontaneous resolution of angioma-like papules during a viral illness. The biopsy specimens from both patients showed a unique histologic appearance consisting of dilated dermal blood vessels with plump, hobnail-shaped endothelial cells. On the basis of the natural history and the histopathologic features we suggest the diagnosis of eruptive pseudoangiomatosis.
