To the Editor We read with interest the study of Bakker et al1 emphasizing that pruritus is an important symptom of bullous pemphigoid (BP). Nevertheless, a number of points warrant respectful comment.
Four of the 15 patients were diagnosed by the authors as having BP based on the immunoserologic analyses, while direct immunofluorescence (IF) findings, which are regarded as key criteria for the diagnosis of BP, were negative. The BP diagnosis made in these 4 patients thus remains questionable and not definitive.
