A group of disease
of the skin and mucous membranes characterized by the formation of blisters. It is though that they may be autoimmune
disorders, since during the active stages of the disease an immunoglobulin may be found in the circulating serum.
occurs usually in persons between the ages of 40 and 60. Large blisters suddenly form on the skin, often
subsequent to blistering in the mouth or nose. The blisters occur most often on the trunk
of the body, in some cases covering very large areas.
In the past, this condition
ended in death; now, however, with the use of steroids, this disease
usually can be controlled. Other forms of pemphigus
exist but generally they are not as severe
as the vulgaris form.
