Abstract: Cutaneous collagenous vasculopathy is a rare idiopathic dermal microangiopathy. We report a case of cutaneous collagenous vasculopathy initially presenting on the trunk and reviews the relevant literature. A 45-year-old female presented with telangiectasia of trunk and limbs for 5 years. Skin histopathology showed hyperkeratosis, increased pigmentation in the basal layer, obvious telangiectasia in the superficial and middle layers of the dermis, thickening of the dilated vascular wall, and seemingly homogeneous changes. PAS staining and Masson staining were positive for vascular wall. The diagnosis of cutaneous collagenous vasculopathy was made.

Key words: cutaneous collagenous vasculopathy, telangiectasia
