Eruptive pseudoangioatosis in an adult renal transplant recipient.

Background. In 1969, Cherry et al. described four children with acute onset angioma-like papules with spontaneous regression during an acute viral inf ection. Similar cases, called eruptive pseudoangiomatosis. have been report ed since and considered to be a viral exanthema. We observed a similar erup tion in a 48-year-old male kidney transplant recipient. Case report. One month after kidney transplantation, the patient rapidly de veloped macules and papules on the trunk. He had unexplained fever 15 days before the eruption. A biopsy specimen revealed dermal blood vessels surrou nded by lymphoid infiltrate. Serology tests were unable to identify any vir us. The lesions resolved spontaneously within 15 days. Discussion. In our patient, eruptive pseudoangiomatosis was diagnosed on th e basis of the clinical and histological features and the disease course. T his case demonstrates that the entity is not limited to children. Further c ases should be studied to determine the precise pathogenics of this uncommo n entity.
