Primary cutaneous angioplasmocellular hyperplasia

Two cases of solitary nodules on the skin of the trunk of young adults showing a peculiar pattern of proliferation of blood vessels and a mixed inflammatory infiltrate with predominance of polyclonal plasma cell infiltration are presented. Follow-up of these patients after complete surgical excision revealed no recurrence. We interpreted the lesions within the morphologic spectrum of plasma cell infiltrates of the skin to be reactive and/or hyperplastic, which we term primary cutaneous angioplasmocellular hyperplasia.
