We are pleased that the topic of activity-induced vasculitis1 has generated additional interest, and we appreciate comments from both Adams and Kelly. We would like to clarify from our perspective the issues addressed in their discussions.
In response to Adams, we note that our purpose in mentioning the lack of articles on activity-induced vasculitis in the American literature was to highlight that frequent omission of this entity from the differential diagnosis of inflammatory purpura may be related to a general unawareness of the association between activity and its precipitation of small-vessel vasculitis. This may in part be related to the lack of original discussion on this topic in the indexed literature and in major dermatology textbooks.
