RESUMEN

A 22-year-old female patient presented with skin flushing in the bilateral legs for 4 years, which gradually spread throughout the whole lower limbs and forearms 6 months ago. Skin examination showed diffuse flushing and dilated capillaries in the lower limbs and both forearms, and the flushing faded after a press. Histopathological examination of the skin lesion on the leg showed hyperkeratosis in a basket-like shape, increased pigmentation in the basal layer, infiltration of the superficial dermis with scattered lymphocytes, with no obvious red blood cell overflow; periodic acid-Schiff staining showed thickened and homogeneous deposits around the blood vessels; immunohistochemical staining showed thickened blood vessel walls and positive staining for type Ⅳ collagen. Diagnosis: cutaneous collagenous vasculopathy.
