Abstract:
Diffuse dermal angiomatosis is an acquired, benign vascular proliferation with poorly circumscribed, violaceous, and livedoid plaques with frequent ulceration. Histologically, there is diffuse and interstitial proliferation of CD31-positive endothelial cells and myofibroblasts within the dermis. Endothelial atypia, mitoses, and vasculitis are lacking. Here we describe a 52-year-old male who presented with erythematous and purpuric patches on the trunk and lower extremities for 2 years. Histologic examination demonstrated a dense proliferation of endothelial cells in the papillary and reticular dermis. Small vascular spaces and extravasated erythrocytes were noted. Immunohistochemical staining using anti-CD31 antibody was positive.
