Eruptive pseudoangiomatosis.
Eruptive pseudoangiomatosis (EPA) is a rare, self-limiting exanthem, which is known to occur primarily in children. It is characterized by an eruption of distinctive erythematous angioma-like papules often surrounded by a pale halo, with histological findings distinct from that of true angiomas. We describe three women with angioma-like papules. The biopsy specimens from them showed a unique histological appearance consisting of dilated dermal blood vessels with plump endothelial cell and perivascular lymphocytes. On the basis of the clinical and histological findings, we present the adult cases of eruptive pseudoangiomatosis and their etiology.
