Dendrocytoclasis in Henoch-Schönlein purpura.
We studied by immunohistochemistry the fate of factor XIIIa-positive dermal dendrocytes in Henoch-Schönlein purpura. We have observed apoptosis affecting most of the perivascular dendrocytes. Such an aspect of dendrocytoclasis has never previously been reported in inflammatory disorders in the absence of vasculitis.
