Cicatricial pemphigoid has been referred to by a variety of designations based largely on its site of involvements, with examples of such terminology including " desquamative gingivitis, " " ocular pemphigus, " and " benign mucous membrane pemphigoid . " However, currently " . . . such designations are thought to be confusing or somewhat misleadings ( e . g ., pemphigus in this context is a misnomer, and this disorder is hardly benign given the extent of morbidity it can cause ) ."
