title: [Diffuse dermal angiomatosis].
abstract: Diffuse dermal angiomatosis (DDA) is a benign, acquired vascular proliferation characterized by painful, poorly circumscribed, livid-erythematous plaques with frequent central ulceration. The clinical features are reminiscent of reactive angioendotheliomatosis or embolia cutis medicamentosa. Histologically, a dense diffuse network of regular capillary vessels throughout the dermis is seen. Endothelial atypia, atypical mitoses or signs of vasculitis are missing. A 43-year-old woman developed a bizarre brownish-livid rapidly growing lesion of DDA 8 centimeters above a surgical scar, shortly after removal of 20 kilograms of fatty tissue from the lower abdominal wall. DDA regressed spontaneously within 12 weeks, and has not recurred over 4 years of follow-up.
