Acquired elastotic haemangioma represents an endothelial proliferation, which commonly presents as a flat or raised erythematouslesion in otherwise healthy individuals.
Histology of acquired elastotic haemangioma
In acquired elastotic haemangioma, sections show prominent solar elastosis with a proliferation of dilated, fine endothelial-lined structures in the upper dermis forming a horizontal band (figure 1, 2). The deep margin of the proliferation is usually well defined. The endothelial lining was bland without multilayering or nuclear atypia. (figure 3).
