Abstract:
Purpura is discoloration of the skin and mucous membranes due to extravasation of red blood cells and may be due to a variety of factors, but it is sometimes difficult to identify the exact cause. Some forms of purpura can frighten the patient and puzzle the physician. Mask phenomenon is an unusual purpura of the relatively loose tissues of the face and neck occuring after prolonged coughing, vigorous vomiting, valsalva's maneuver, parturition, or any other exertion that raises intrathoracic or abdominal pressure. This occurs with acute onset and fades within twenty-four to seventy-two hours spontaneously. A work-up for a coagulation or platelet defect is usually not required. We herein describe five cases of mask phenomenon(unusual facial purpura).
