Nonbullous pemphigoid / 中华皮肤科杂志

Nonbullous pemphigoid (NBP) , which is related to bullous pemphigoid, has various clinical manifestations, and is frequently accompanied by itching. Typical clinical manifestations of bullous pemphigoid (BP) , such as tense blisters or bullae, are absent in NBP cases. It is easy to misdiagnose. Histopathological findings are not specific, and its diagnosis should be confirmed by direct immunofluo-rescence, indirect immunofluorescence or salt-split indirect immunofluorescence. NBP may develop into BP in some cases, and the prognosis of NBP is better than that of BP. However, delayed diagnosis usually leads to a relatively high dosage of drugs for disease control, and a high rate of adverse reactions.
