Abstract

Calcium channel blockers are widely used antihypertensive drugs, which are uncommonly associated with cutaneous reactions, such as pruritus, urticaria, or alopecia. Photosensitivity presenting with telangiectasia has rarely been described. We present here a case of photodistributed telangiectasia induced clinically by amlodipine and histologically by enlarged capillaries in the upper dermis without signs of vasculitis.
