Purpuric pityriasis rosea.


The clinical and histopathologic findings made possible the diagnosis of an atypical variety of PR, a previously healthy 2-year-old boy seen for a cutaneous eruption of four days' evolution that could not be diagnosed on clinical grounds alone, but that had two rather characteristic histologic findings.
