Quizplus · Accepted Answer

Skin blisters can be caused by a wide variety of agents. Small blisters, especially when they occur in clusters on a background of inflamed skin, are called vesicles. Vesicle formation is characteristic of herpes simplex infection of the skin. Larger blisters (called bullae) are characteristic of exposure of the skin to poison oak or poison ivy (Toxicodendron species). In poison oak or poison ivy exposure, the bullae are often find in a line because a leaf of the poisonous plant draws a line along the skin as hikers walk past it. Pemphigus vulgaris is an autoimmune cause of skin blistering. Scabies infestation, in which a small parasitic mite burrows into the skin, laying eggs that stimulate an allergic response, is typically not a cause of skin blistering.
