    Cutaneous collagenous vasculopathy with generalized telangiectasia in two female patients.

    Cutaneous collagenous vasculopathy is characterized by generalized cutaneous telangiectasia and unique microscopic and ultrastructural vascular changes, consisting of marked collagen deposition within the vascular walls of the post-capillary venules in the superficial dermis. There are only 4 previous cases described in the medical literature, all in males, mostly middle-aged. We have recently seen two female patients with clinical and histopathologic features diagnostic of cutaneous collagenous vasculopathy, indicating that it is not restricted to males. As cutaneous collagenous vasculopathy can be clinically indistinguishable from generalized essential telangiectasia, and histopathologic studies are rarely performed for this condition, it is likely that cutaneous collagenous vasculopathy frequently passes unrecognized, but it may be more common than previously thought.

    Background: Cutaneous collagenous vasculopathy (CCV) is an entity first described in 2000 by Salama and Rosenthal [1]. Because of its rarity, we felt it opportune to report the present case.

    Patients And Methods: We describe the case of a 47-year-old woman presenting with widespread telangiectasia distributed symmetrically on the legs, thighs and lower abdomen. Read More

    Cutaneous collagenous vasculopathy is a very rare entity first described in 2000, manifesting clinically with acquired, progressively diffuse, cutaneous telangiectases with a histologically distinct aspect, characterized by a thick hyaline collagenous wall. Its cause is unknown. Differential diagnosis includes mainly generalized essential telangiectasia and telangiectatic mastocytosis. Read More

    We describe a 16-year-old girl who presented with a 3-year history of telangiectatic patches on the extremities and trunk. Skin biopsies demonstrated dilated vessels with thickened walls containing hyaline material in the papillary dermis, resembling those seen in systemic amyloidosis, porphyrias, or lipoid proteinosis. A diagnosis of cutaneous collagenous vasculopathy was made. Read More
