Cutaneous collagenous vasculopathy: report of the first pediatric case.

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. To our knowledge, cutaneous collagenous vasculopathy has previously only been described in adults aged 50 and older.
