Eruptive pseudoangiomatosis in adults with immune system disorders: A report of two cases

Abstract

Eruptive pseudoangiomatosis is a cutaneous disease of unknown origin, characterized by the sudden appearance of small, asymptomatic angioma-like erythematous papules surrounded by a pale halo that resolves spontaneously. It occurs due to transitory dermal blood vessel dilation and has been associated with viral infections and hematologic disorders. To this day, it remains a disease that affects mostly the lower spectrum of life. Most of the cases have been reported in children and few reports have described its association with immune system disorders. The diagnosis is based upon clinical presentation. Histopathological analysis has no pathognomonic findings and can include dilated dermal blood vessels, perivascular lymphocytic infiltration and plump endothelial cells. We report a 21-years-old female diagnosed with HIV in AIDS stage and a 19- years-old male diagnosed with non- Hodgkin’s lymphoma.
