It may present with intermittent nasal bleeding, blurred vision, pustule formation and/or disfigurement. Overlying skin may be of normal appearance or may manifest a red, pulsatile mass with local rise of temperature. Other features may include pain, ulceration, excessive growth and/or congestive heart failure."
