Cutaneous collagenous vasculopathy (CCV) is a rare distinct idiopathic microangiopathy of the superficial cutaneous vasculature. Seven new cases are reported (6 females and 1 male) ranging in age from 42 to 85 years, with some showing unusual clinical and histopathological findings. All presented with macular telangiectases starting on the lower extremities and spreading progressively in 5 cases and were suspected to have generalized essential telangiectasia. Read More

Reactive cutaneous vascular proliferation or angiomatosis is associated with various conditions, but is rarely seen secondary to vascular occlusion. We report an unusual case of a 79-year-old female who presented with 8 month history of purpuric facial plaques, with painful crusted ulceration of the nose, later developing similar eruptions on hands, thighs and trunk. Biopsies showed marked angioproliferation, with intravascular (IV) hyaline deposits (PAS+, fibrin+/-; IgM+, fibrinogen+, and C3+), associated with endothelial hyperplasia (Factor VIII+, Vimentin+).
